I have to compleate and balance these equations and I need help on how to do them...

Ca + H20 >>>>
ZnCO3 + H3PO4 >>>>
FeSO4 + (NH4)2S >>>>

Also I wanted to check if Cl2 + NaBr has no reation.
Thanks alot...

Ca + 2H2O ===> Ca(OH)2 + H2(g)

3ZnCO3 + 2 H3PO4 ===> Zn3(PO4)2 + 3CO2 + 3H2O

FeSO4 + (NH4)2S ===> FeS + (NH4)2SO4

Cl2 + 2NaBr ==> 2NaCl + Br2 Chlorine does indeed displace bromine from solution.

Ca + H2O >> H2+ CaO
ZnCO3+H3PO4>>> HCO3 + Zn3PO4 im iffy on this one
FeSO4+(Nh4)2s>>> im not sure with this one
