What are the products of these equations?

Question

1) NH4NO3 + NaOH -> NH3+H2O+NaNO3 ???

2) FeSO4 + HCl -> ?? No idea...

3) CaCl2 + H2SO4 -> ? CaSO4+HCl ?

All of them are in water. Please tell me if the products are liquids, solids or gases. And if you can tell me how you did it... Thank Youuuuuu!!!!

Answer 1

2)There is a reaction. In the first place, if the FeSO4 is solid (and not in solution) it will dissolve. Then, the Fe will form the following complex ion with Cl- coming from the acid:

[FeCl4]2-

Because of this, you would get a yellow solution as a the product of this reaction

Answer 2

1) NH4NO3 + NaOH -> NH3(aq) +H2O(l) +NaNO3(aq)

yes

2) FeSO4 + HCl -> no reaction

3) CaCl2 + H2SO4 ->  CaSO4 (s) + HCl (aq)

yes
