How would you write a balanced chemical equation, including states, for the following?

Question

1. Silver nitrate solution is mixed with a sodium chloride solution.

2. Solid calcium chloride and solid aluminum sulfate react when heated producing calcium sulfate and aluminum chloride.

3.. Aluminum metal reacts with sulfuric acid to produce hydrogen gas and aluminum sulfate.

4. Solid alumninum phosphate reacts with aqueous sodium sulfate

Answer 1

I think this is what you are looking for: aq = aqueous; s = solid(either insoluble product or starting material added without solvent); g = gas

AgNO3(aq) + NaCl (aq) > AgCl (s) + NaNO3(aq)

3 CaCl2 (s) + Al2(SO4)3(s) > 3 CaSO4 (s) + 2 AlCl3 (s)

2 Al(s) + 3 H2SO4(aq) > Al2(SO4)3(s) + 3 H2(g)

2 AlPO4(s) + 3 Na2SO4(aq) > Al2(SO4)3(s) + 2 Na3PO4

(aq) (This last (aq) belongs after the Na3PO4, but it wouldn't fit!)
