FINISH EQUATION/NET IONIC PRACTICE
Complete and balance the following equations. Put `NR' if no reaction should occur. Then write a net ionic reaction for each. Also give the driving force for each equation and the type of equation.

a). 2KOH(aq) + H2SO4(aq) --> 2H2O(l) + K2SO4
net ionic = 2OH
-(aq) + 2H+ (aq) 2H2O(l)
OH
-(aq) + H+ (aq) H2O(l)

Driving force = formation of water

Type = acid/base double displacement (metathesis)

b.) Pb(s) + Cu(NO3)2(aq) --> Pb(NO3)2(aq) + Cu(s)
net ionic = Pb(s) + Cu
2+ (aq) Pb2+ (aq) + Cu(s)

Driving force = transfer of electrons

Type = displacement (single displacement)

c.) BaCl2(aq) + H2SO4(aq) --> BaSO4(s) + 2HCl (aq)
net ionic = Ba
2+ (aq) + SO42- (aq) BaSO4(s)
Driving force = formation of a solid ppt

Type = double displacement (metathesis)

d.) C4H8(g) + 6O2(g, excess)--> 4H2O(g) + 4CO2(g)
Note: with burning water is shown as a gas due to the high temperatures
net ionic = none (nothing ionizes; so it is the same as the molecular equation)

Driving force = transfer of electrons

Type = combustion, redox

e.) BaCl2(aq) + HNO3(aq) -->NR

f.) 2ZnO(s) heat --> 2Zn (s) + O2(g)
net ionic = none
Driving force = formation of a gas

Type = decomposition

g.) HClO3(aq) + LiOH(aq)  -->  H2O(l) + LiClO3(aq)
IF YOU CONSIDER HClO
3(aq) AS A STRONG ACID:
net ionic = H+ (aq) + OH-(aq) --> H2O(l)
IF YOU CONSIDER HClO
3(aq) AS A WEAK ACID as Kotz and OWL does THEN:
net ionic = HClO
3(aq) + OH-(aq) --> ClO3-(aq) + H2O(l)
Driving force = formation of water

Type = acid/base double displacement (metathesis)

h.) Ni(s) + FeCl2(aq) --> NR
