I have a attached a document with 5 chemical equations that need to be solved. The purpose of the assignment is to determine if a precipitate forms. Please see attached for further instructions, I have worked out the problems to the best of my knowledge.


I need help with these equations, can you please check to see if I did these correctly? I need to write the
balanced formula unit, total ionic and net ionic equations for each. If no precipitate forms, I’m supposed to
write “ ? NR” for no reaction. I also need to note all physical states of reactants with (aq), (s), (l), (g) --I’m unsure about which need to be liquids and gases. Also, I’m not sure if I’m even writing the
balanced/total/net equations correctly in terms of format. There are a total of 5 equations below. If there is
something wrong, can you please put it in a different color and explain why it’s wrong.
Thank you!
Fe(NO3)2 (aq) + K3PO4 (aq) ? ?
So for this one I’m confused because the iron doesn’t balance to form phosphate ppt, so should this be NR?
Or a solid ppt? The equation was written exactly like this, and I don’t think I’m supposed to balance it,
because maybe that’s the point of the question?
Balanced:
Fe(NO3)2 (aq) + K3PO4 (aq) ? FePO4 (s) + K3(NO3)2 (aq)
Total Ionic:
[Fe2+ (aq) + 2NO3- (aq)] + [3K+ (aq) + PO43- (aq)] ? FePO4 (s) + 3K+ + 2NO3- (aq)
Net Ionic:
Fe2+ (aq) + PO43- (aq) ? FePO4 (s)

Ba(OH)2 (aq) + Pb(ClO3)2 (aq) ? ?
Balanced:
Ba(OH)2 (aq) + Pb(ClO3)2 (aq) ? Pb(OH)2 (s) + Ba(ClO3)2 (aq)
Total Ionic:
[Ba2+ (aq) + 2OH- (aq)] + [Pb2+ (aq) + 2ClO3- (aq)] ? Pb(OH)2 (s) + Ba2+ (aq) + 2ClO3- (aq)]
Net Ionic:
Pb2+ (aq) + 2OH- (aq)? Pb(OH)2 (s)

Al(ClO4)3 (aq) + Na2SO3 (aq) ? ?
This one doesn’t really balance either….
Balanced:
Al(ClO4)3 (aq) + Na2SO3 (aq) ? 2Al(SO3)3 (s) + 2NaClO4 (aq)
Total Ionic:
[Al3+ (aq) + 3ClO4- (aq)] + [2Na+ (aq) + SO32- (aq)] ? 2Al(SO3)3 (s) + 2Na+ (aq) + 3ClO4- (aq)
Net Ionic:
2Al3+ (aq) + 3SO32- (aq) ? 2Al(SO3)3 (s)

CaCl2 (aq) + (NH4)2SO4 (aq) ? ?
Balanced:
CaCl2 (aq) + (NH4)2SO4 (aq) ? CaSO4 (slightly soluble??) + 2ClNH4 (aq) (or NR??)
Total Ionic:
[Ca2+ (aq) + 2Cl- (aq)] + [2NH4+ (aq) + SO42- (aq)] ? CaSO4 (slightly soluble??) + 2Cl- (aq)] + 2NH4+ (aq)
Net Ionic:
Ca2+ (aq) + SO42- (aq) ? CaSO4 (slightly soluble??)

LiCH3COO (aq) + MgCl2 (aq) ? ?
Balanced:
2LiCH3COO (aq) + MgCl2 (aq) ? 2LiCl (aq) + Mg(CH3COO)2 (aq) (is this no reaction??)
Total Ionic:
2Li+ (aq) + 2CH3COO- (aq) + Mg2+ (aq) + 2Cl- (aq) ? 2Li+ (aq) + 2CH3COO- (aq) + Mg2+ (aq) + 2Cl- (aq) (is
this no reaction??)
Net Ionic: NR?
