Conversion factors, constants, and equations that you might need:
h = 6.626 x 10-34Js c = 3.00 x 108m/s NA = 6.022 x 1023 atoms/mo le
λ = h/(mv) E = ½ mv2 E = hc/λ

1. Identify the precipitate or precipitates (if one or more exists).
(3 pts each)
a) NaCl(aq) + Hg2(NO3)2(aq) Hg2Cl(s)
b) Ba(ClO3)2(aq) + CaSO4 (aq) BaSO4 (s)
c) Co(C2H3O2)2 (aq) + LiCO3 (aq) CoCO3 (s)
d) NH3OH(aq) + CuI2(aq) CuOH(s)
a) Pb(NO3)2(aq) + Li2SO4(aq) PbSO4(s)
2. Write balanced chemical reactions for the unbalanced reactions of the following
reactants
(5 pts each)
a) C6H6(l) + O2(g) → CO2(g) + H2O(l)
C6H6(l) + (15/2)O2(g) → 6CO2(g) + 3H2O(l)
Or
2C6H6(l) + (15)O2(g) → 12CO2(g) + 6H2O(l)
b) NaCl(aq) + Pb(NO3)2(aq)
2NaCl(aq) + Pb(NO3)2(aq) → PbCl2(s) + 2NaNO3(aq)
3. Write down the net ionic equation for the reaction
(10 pts)
2AgClO3(aq) + CaCl2(aq) → 2AgCl(s) + Ca(ClO3)2
Ag+ (aq) + Cl-(aq) → 2AgCl(s)
