1. Can I use a TI-83 calculator?
No, you can not use a TI-83 since it has alphabetic memory. You need a TI 30 or 36 or its Casio equilivent. The calculator cannot have alphabetic memory. It should cost $9-12. Be sure to buy one with the keystrokes you like. For example: TI-83 require that you put in log then the number. If you want this same keystroke for your lower calculator, then at the store, hit the log button. If the calculator gives you an error, this calculator will require that you put in the number, then hit log. If the calculator says log and is ready for the number, this calculator has the same keystrokes as your TI-83.
1) In (16.122 + 2.3)/ 1.461, how do we decide significant figures?
The rule for adding and subtracting is that you use the smaller number of decimal places. Since 16.122 has 3 decimals and 2.3 has 1 decimal, the number on top will be counted as having 1 decimal. This is confusing since you really leave it all in your calculator. You consider the 1 decimal at the end when rounding the final answer. (16.122 + 2.3) = 17.422 , but really only 17.4 is significant. Again leave all (17.422) in the calculator and divide by 1.461. The rule for division and multiplication is that the answer will have the smaller number of sig figs (pay no attention to where the decimal is). So 17.4 is 3 and 1.461 is 4 sig. figs so the final answer will have 3 sig figs.
2) What is the formula for standard deviation?
3) Metric Prefixes on the OWL homework.
If you need the table for prefixes for those prefixes that you don't have to memorize, follow these steps. (Now you have been told to memorize kilo-, centi-, milli- and nano-) Hit the ebook link on the left side of the screen. This will popup in a new tab. Then go to page 26 in your textbook. There is the table of prefixes.

Atoms and Trends:
1) Can you go over calculating atomic mass from isotopes again?
Element X is 98.7% X-13 and 1.3% X-12
What is the atomic mass?
Step 1: Change % to decimal (98.7% --> .987 AND 1.3% --> .013)
Step 2: Multiply each decimal by the mass of the isotope
(.987 x 13) and (.013 X 12)
Step 3: Add the mass from each isotope to = the atomic mass
(12.831) + (0.156) = 12.987
2) How do you solve for % given the atomic mass? I know how to go from % to atomic mass, but this is reverse.
You know that the atomic mass from the chart is 6.941 and that this is made up of Li-6 and Li-7. The % of Li-6 + the % of Li-7 = 100. So you can let one of them = x % and the other 100-x%.
If you let Li-6 = x% and Li-7 = 100-x%, then
6.941 = (1.00 -x) 7.01600 + (x) 6.01512
Solve for x
3) How do you determine which element is largest for 2nd I.E.?
Write out the electron structure. Take away one electron. Now which would require the most energy to remove the 2nd electron. For example: Using the Bohr model Na is 2)8)1) so the Na ion would be 2)8). Using the Wave Mechanical model: Na is 1s2, 2s2, 2p6, 3s1 The first electron is easy to remove, because it is in the 3s, the second electron is from a full p level and very hard to remove. The first ionization energy for Na is low (easy to remove), the 2nd ionization energy is high (hard to remove).
4) How do we explain the trends?
Energy levels increase as you go down a column, and effective nuclear charge increases as you go across a row. The trick is to apply these things to the trends that you memorized. Let me give you an example with atomic size and electronegativity.
You memorized that atomic size increases as you go down a column, which can be explained by the increasing # of electron shells. You memorized that electronegativity decreases down a column (increases as you go up), which can be explained by the idea that with increasing # of electron shells, the tendancy to gain an electron would decrease as the valence shell gets further from the nucleus.
You memorized that atomic size decreases across a row (increases to the left), which can be explained by the increasing effective nuclear charge across. With strong effect. nuclear charge, the pull on the valence shell will make the atom smaller. You memorized that electronegativity increases as you go across a row, which can be explained by the increasing effective nuclear charge as you go across a row. The more the nucleus pulls the valence shell, the more likely the atom will have a tendancy to gain an electron.
The only variations in this is the difference a fully-filled s orbital or 1/2 filled p or d orbital makes.
Wave Mechanical Model:
1) What is core notation?
When writing out the electron conf. of K (or anything thereafter) You have a choice:
The complete electron config for K is:
1s2, 2s2, 2p6, 3s2, 3p6, 4s1
A condensed way to show K is to show the nearest noble gas in brackets. [Ar] 4s1
This works because [Ar] = the electron conf of Ar = 1s2, 2s2, 2p6, 3s2, 3p6,
It can be done will all noble gases, so a condensed or core notation way to show Sr is: [Kr] 5s2
instead of the full electron conf. 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10, 4p6, 5s2
2) Why does Ni end in a 4s2 instead of a full 3d10?
It depends on whether you write it in the order the levels are from the nucleus OR in the order of increasing energy (they way electrons fill).
Ni = [Ar] 4s2, 3d8 is the same as [Ar] 3d8, 4s2 The first is in energy order, the second is in order from the nucleus.
3)Can you explain the electron configuration and orbital configuration for Sc & Cd ?
Sc = [Ar] 4s2, 3d7 is the same as [Ar] 3d7, 4s2 so you would show all orbitals filled with an up arrow and a down arrow, except 3d. For 3d you have 5 orbitals, but 7 electrons. Since electrons fill with 1 in each orbital, you will have 3 of the d orbitals with both arrows, and 3 of the d orbitals with a single arrow.
Cd =[Kr] 5s2, 4d10 which means all filled with 2 arrows for the [Kr] part, then 2 arrows in the single 5s orbital and 2 arrows in the five d orbitals.
4) Why do the electron configurations for Tl and Bi contain 4f14? I got the [Xe] and the last sublevels, but not the f sublevel in my answer.
Ti is element # 81, so the nearest noble gas is [Xe], then 6s2, then notice than that element number 57 is followed by element 58, which is in the lower f series. So Ti = [Xe] 6S2, 4f 14, 5d10, and 6p1. Also note that Xe is element # 54 so
54 electrons (Xe) +2 (6s) + 14 (4f) + 10 (5d) + 1 (6p) = 81
If you leave out any of these you won't have 81 electrons.
5) Can you explain how to determine the orbital spin for a specific sublevel?
Each orbital can contain 2 electrons, one will spin one direction, one the opposite direction. If there is 1 electron in the orbital, we usually put it in an orbital diagram as an up arrow, but I would not expect you to say if it's spin quantum number is +1/2 or -1/2
6) How many orbitals in any atom can have the given quantum number or designtion D) n=5 ? I came up with 23 orbitals since energy level 5 has s, p, d, and f 1+3+5+7=16..how did solutions manual get 25
The 5th level has s, p, d, f so 1, 3, 5, and 7 = 16. The 5th level is predicted to have s, p, d, f, and g (although no known elements have the g). So 1, 3, 5, 7, and 9 =25.
7) What are the answers to the practice sheet that has 3
questions about electron configurations? Click here for the
quantum numbers worksheet!
The answers are:
1) The Cl- ion puts its last electron in the 3p level so:
n = 3;
ml= 1, 0, or -1;
ms = +1/2 or -1/2
n = main shell;
l = shape or sublevel;
ml = orientation;
ms = spin
2) Cu = [Ar] 4s2, 3d9 from the chart, but is an exception, so really Cu = [Ar] 4s1, 3d10
The Cu 1+ = [Ar] 3d10 and is diamagnetic;
3) size = Rb; trend is larger down & to left
size = Br-; Rb+, Sr2+; and Br- have same # of electrons and Br has fewer protons.
1st IE = O; trend is larger up and to right
2nd IE = K; both K and Rb have a noble gas config. after 1 electron has been removed, so MUCH energy to remove 2nd electron, but K is smaller and nucleus can pull harder
EA = O; trend is larger up and to left
1) Is there more practice on converting between molecules, moles, and grams? Here is a practice sheet that has 10 questions:
THE QUESTIONS ARE:
1. ? moles H2O = 36 g
2. ? molecules H2O = 36 g
3. ? g H2O = 0.5 mole
4. ? g H2O = 1 x 1023 molecules
5. If 88 g of X = 2 moles, what is the molar mass of X?
6. If 56 g of Y = 1.2 x 1024 molecules, what is the molar mass of Y?
7. If 3.01 x 10 24 atoms is 95 g of an element, what is the atomic mass?
8. In 66 g of CO2 there are:
how many moles?
how many molecules?
how many oxygen atoms?
9. If 1215 AMU of an element is 8.306 x 10 - 23 moles:
how many atoms are in the 1215 AMU?
what is the Atomic Mass?
how many grams are in the 1215 AMU?
10. What is the mass percent composition of Ca(HSO4)2?
The answers are: (1) 2.0 mol H2O; (2) 1.2 x 1024 molecules; (3) 9 g H2O; 4) 3 g H2O; (5) 44 g/mol; (6) 28 g/mol; (7) 19 amu/atom; (8) 1.5 mol CO2; 9.0x 1023 CO2 molecules;18 x 1023 O atoms; (9) 50.02 atoms; 24.3 amu/atom; 202 x 10-23 g; (10) 17.1% Ca; 0.8% H; 27.4% S; 54.7% O
If 88 g of X = 2 moles, what is the molar mass of X?
Molar mass is the # of grams in 1 mole. You know the grams (88) in 2 moles, so
88g/2mol = 44 g/mol = molar mass
If 3.01 x 10 24 atoms is 95 g of an element, what is the atomic mass?
Again, molar mass is the # of grams in 1 mole and is the same number as the atomic mass (only the units differ).
Here you know the grams (95) and the number of atoms. Since 6.02 e23 atoms makes up 1 mole, you can find the number of moles from the atoms given. 3.01 e 24 (1 mole / 6.02 e23 ) = 5.00 moles
So use the definition of molar mass: 95 g / 5.00 moles = 19 g/mol = molar mass
Then use the idea that molar mass and atomic mass are the same # only different units:
so atomic mass = 19 amu/atom
8.306 e-23 moles (6.022e23 atoms/mole) = 50.02 atoms
atomic mass = amu/atom ...so 1215 AMU/50.02 atoms = 24.3 AMU/atom
24.3 AMU/atom would be 24.3 g/mol of atoms .....So 24.3g/mol ( 8.306 e-23 mol) = 201.8 e-23 g = 2.02 e-23g

2) In the equation to convert Celsius to Kelvin, should we use "C+273=K" or "C+273.15=K" in our calculations?
Often it will not matter, due to sig figs, but C + 273.15 = K is more accurate and will give the most sig figs.
3) You mentioned in class that we should use the atomic mass rounded to the nearest tenths place. When we are adding the atomic mass of two or more elements, should we start our calculations by using the rounded number, or should we round after we add the numbers together?
1P=30.9738 or 31.0
5Cl=177.2635 or 177.3
mass="208.2373, rounding off to 208.2" or "208.3" if you used the masses with 1 decimal.
I would round with the atomic mass:
so P = 31.0
for Cl use 35.45 x 5 = 177.25 so the formula mass is 208.25 or really 208.3
For exams, we will usually use a table that has 1 decimal, sometimes 2, except for the nuclear chapter..
4) How do you find molecular formulas?
The empirical formula times a whole number = the molecular formula.
If you know the empirical and the molecular, then:
molecular formula mass/ empirical formula mass = whole number
This is the whole number that you multiply the empirical formula by: so if the empirical formula is HX and when you are given the molecular mass, you find the whole number is 3, the actual molecular formula is H3X3.
5) Can you repeat the naming rules and give us the list of 10 ions to memorize?
Click here for the naming rule and the list of 10 ions to memorize.
6) Why is H3PO4 called phosphoric acid rather than perphosphoric acid and why is H2SO4 called sulfuric acid rather than persulfuric acid?
See the handout about acid's. when the -ate ion is mixed with H+ to form an acid, it is called --ic acid. so SO4 (2-) is sulfate so H2SO4 is sulfuric acid. Likewise the PO4(-3) ion is called phosphate, so the acid form is phosphoric acid. It depends on what ion is mixed with H+, not on the amount of O's or H's. H2SO5 , if it exists, would be persulfuric acid because it is H+ added to the persulfate ion, which has one more oxygen than the sulfate ion that you memorized.
7) Can you give us more practice with naming?
See these 2 websites for more practice (both have a place you can click for the answers):
8) If you know that you have a hydrated compound of CoCl2 and that the mass of the hydrated compound was 31.04, but after heating the mass was 16.94, how do you find the actual formula of the hydrated compound?
You know that the actual formula is CoCl2 * X H2O, but you have to calculate the mole ratio of water to anydrous compound. You are to assume that all of the water was removed with heating. So you calculate the moles of the anydrous compound, then the moles of water
moles of CoCl2 = 16.94 g ( 1mol/129.84g) = 0.1305 mol CoCl2
moles of water = 31.04-16.94 = 14.10g ( 1mol water / 18 g) = 0.7825 mol water
next divide each by the smallest, like you do empirical formulas
moles of CoCl2= 0.1305 mol CoCl2/ 0.1305 = 1
moles of water = 0.7825 mol water/ 0.1305 = 6
So the formula is CoCl2 * 6H2O
Bonding and Geometry:
1) I'm emailing you because I have a question
about the polarity of molecules. Is it set that, for example, all linear shaped molecules are nonpolar, all bent/angular shaped molecules are polar, all triangular plane
shaped molecules are nonpolar, etc?
This is basically true, if the atoms that attach to the central one are all the same. For example: CCl4 and CHCl3 are both tetrahedral, but CCl4 is nonpolar & CHCl3 is polar.
IF the atoms attached to the central on are all the same:
tetrahedral molecules are nonpolar
triangular bipyramidal are non polar
octahedral are nonpolar
Otherwise ( & for other shapes), consider each bond. Find the negative end of each bond. Use the "horse" analogy, assume that the 'horses' are all running toward the negative end. If the center will move, the molecule is polar. If the center will not move, the molecule is nonpolar.
2) What are the regions of electron density, the shape, the angles and the polarity for PCl3?
there are 4 regions of electron density,
the structure is pyramidal (triangular pyramidal),
the bond angles are less than 109.5 degrees (the lone pair pushes the bonds closer),
the molecule is polar.
3) See a good video on molecular bonding and geometry at: https://m.youtube.com/watch?v=f8FAJXPBdO

CLICK HERE FOR THE SOLUTIONS TO THE 4 QUESTIONS.
4) I was just wondering which solubility guidelines we need to memorize in order to determine if a salt is soluble or not.
Good Question! I usually ask students to know the basics (almost all sodium, potassium, ammonium, chloride, and nitrate salts are soluble.) If you need more than that, the problem will say "soluble potassium hydroxide" or KOH (aq) or will give you a solubility table.
5) Describe what is meant by redox or oxidation/reduction?
When an atom or ion loses electrons, it is oxidized, it is the reducing agent, and it increases in oxidation number (the number becomes more positive). When an atom or ion gains electrons, it is reduced, it is the oxidizing agent, and it decreases in oxidation number (the number becomes more negative).
For example if Cu+ loses another electron to become Cu2+, it is oxidized, it is the reducing agent, and its oxidation number goes from +1 to +2 or becomes more positive. IF Cu+ gains an electron to become Cu, it is reduced, it is the oxidizing agent, and its oxidation number goes from +1 to 0 or becomes more negative.
6) What about some practice on net-ionic equations ?
Click Here for a problem set with equations (a) through (h) AND the solutions. Remember that if a substance is aqueous, you split it into ions for the total or complete ionic equation, with the acception of aqueous weak acids and weak bases. To say it another way, DO NOT split solids, liquids, gases, aqueous weak acids, or aqueous weak bases into ions for the total ionic. By canceling substances on both sides of the arrow, you can get to the net ionic.
Weak acids are those NOT on the list of the 6-7 strong acids(HCl, HNO3, HI, HBr, H2SO4, HClO4---some books list HClO3, but not Kotz or OWL).
Weak bases are thosethat are not hydroxides of first family metals or 2nd family metals beginning with Ca.

Click here to go to a website that will give you 10 practice questions and answers.
8) Can you give us practice limiting reagent problem?
Click here for a pdf of the limiting reagent problem & solution.
1) What are the important things to remember about calorimetry?
- the equation q = m s deltaT, sometimes written as q = m c deltaT
- The delta means means change and this is final minus initial or after the reaction minus before the reaction.
q= heat - usually in Joules
c or s = specific heat-usually in J/(g x degrees C) or in J/(g x K)
- qhotwater = qcoldwater + q calorimeter The heat given off by the hot water is equal (but opposite in sign) to the heat gained by the cold water, plus the heat gained by the calorimeter itself.
- qhotwater = qcoldwater + q calorimeter could be expanded to be: m s deltaT of the hot water = m s deltaT of the cold water + K(calorimeter constant) delta T
- Negative q means heat given off; postive means heat absorbed.
- a coffee cup calorimeter is at constant pressure so q = delta H.
- When you have a reaction, then qreaction = qwater + q calorimeter which is expanded to:
delta H of the reaction = m s deltaT of thewater + K(calorimeter constant) delta T
- signs of deltaHrxn and delta Hsoln are reversed. The heat absorbed by the calorimeter plus heat gained by the solution is equal (but opposite in sign) to the heat lost by the reaction or process in an exothermic reaction.
2. How do you find the final temperature when a hot piece of metal is put into a liquid,?
You will use the idea that the heat the metal loses plus the heat the liquid gains = 0 (the change in the energy of the universe is zero.) It is true that you are ignoring any heat lost to the equipment, but we will ignore that.
q metal + q liquid = 0
ms(Tf-Ti) + ms(Tf-Ti) = 0
[mass of the metal x specific heat of the metal (Tf -Tinital of the metal) ] + [mass of liquid x specific heat of liquid (Tf -Tinital of the liquid) ] = 0
So multiply mass of the metal x specific heat of the metal to get a #.
If this # is 9.7, and the T initial is 80.0 degrees C, then you have 9.7 (Tf-80.0), when you distribute the 9.7 across, you will get 9.7Tf - 776
You will do the same for the liquid side.
If the multiplication of the mass of the liquid and the specific heat of the liquid gives you 4.5 and the initial temperature is 10.0, you get 4.5 (Tf-10.0).
When you distribute the 4.5 across, you will get 4.5Tf - 45.0
So you have [9.7Tf - 776]+[4.5Tf - 45] = 0
Add to get 14.2 Tf - 821 = 0
So 14.2 Tf = 821
Divide by 14.2 to get Tf = 57.816 or 57.8 for the final temp, which makes sense as the hot metal was a 80 degrees and the liquid was at 10 degrees, when combined the final temp is 57.8
States of Matter:
**See the tanker car implode due to cooling vapor which causes lower pressure inside than the atmospheric pressure outside at: https://www.youtube.com/watch?v=E_hci9vrvfw
1) When determining the pressure of a certain gas over water, will the pressure of water always be given? Is it always 24 torr?
You will either have a chart or be given the vapor pressure of water at the temperature. Vapor pressure is related to temperature so the 24 torr is for a specific temperature.
2) Do the gas particles at one temperature have the same speed?
No, at the same temp all have the same KE; but not the same speed (or velocity).
KE = 1/2 mV2
3) In my notes from lecture I wrote that gas particles that take up the most space (have a greater MW of # of electrons) will deviate the most from ideal. Which will be nearest ideal H2 , F2 or HF? I think H2 b/c it is smaller and will move faster and therefore have fewer attractions. So when asked which would deviate most from ideal I answered F2 b/c it was heaviest and slowest. But this is not the correct answer. HF is the answer. Why is this? Is the MW/# electrons method not always the best way to determine the answer?
For now you can think of this as HF being a polar molecule, and having more attraction between molecules. Always use the type of IM force to separate first. H2 and F2 have only London forces, while HF has hydrogen bonding. ...so HF will deviate the most (more attraction between molecules) because of the stronger IM force. Then between the 2 with London forces, use the MW to determine that H2 will behave most like ideal because it is the lightest.
4) At 333K, which of the pairs of gases below would have the most nearly identical rates of effusion??
a) N_2_O and NO_2_
b) CO and CO_2_
c) CO and N_2_
d) N_2_ and O_2_
e) NO_2_ and N_2_O_4_
this question is from fall 2000, the correct answer is C..
rates of effusion depend on molar mass. (same KE, but KE = 1/2 mv2 ; heavy particles move more slowly, etc.)
a) 44 g/mol compared with 46
b) 30 g/mol to 44 g/mol
c) 28 g/mol compared to 28 -----has the same Molar Mass.
d) 28 g/mol to 32 g/mol
e) 46 g/mol to 92 g/mol
5)What is boiling?
Boiling is the point where the vapor pressure of a liquid equals the atmospheric pressure. A liquid with high vapor pressure at room temperature will need just a little added heat to increase the vapor pressure to the atmospheric, so boiling pt will be low. (higher IMF = higher bp).
6) What is viscosity, surface tension, capilary action, and vapor pressure?
Viscosity is the resistance to flow of a liquid (higher IMF = more viscosity); surface tension is the 'beading' up of water, it is caused by the attraction of surface molecules to interior molecules (higher IMF = higher surface tension); capillary action is when a liquid climbs up a wick or rises in a glass tube, this depends on the IMF of the liquid molecules compared to those between the liquid and the glass. (higher IMF = lower capillary action); vapor pressure is the pressure created by gas molecules above the surface of the liquid from which they have escaped (higher IMF = lower vp or slower evaporation).
7) HEATING GRAPH SHOWING PHASE CHANGES: On the graph comparing the temperature of water at different states, why was the temperature leveled out for the solid and water phase?. Is that saying that ice water is a constant temperature of 0 degrees Celsius?
This is a good question. During the level parts of the graph, heat is being used to break up the IM forces to change the state rather than being used to increase the temperature.
8) How do the IM Forces compare? NOTE: these are intermolecular forces NOT intramolecular (those inside 1 molecule).

9) What is the relationship between Intermolecular forces and physical properties?
................Ionic > hydrogen b.> dipole-dipole > London f.
IF IMF is higher b.p. goes up m.p. goes up Vapor pressure goes down Viscosity goes up Surface Tension goes up Capillary action goes down Evaporation goes down delta H vaporization goes up delta H fusion goes up
