Balancing Equations?

I can’t seem to balance these equations correctly:

ZnS + O2 → ZnO + SO2

Ca3(PO4)2 + HNO3 –> Ca(H2PO4)2 + Ca(NO3)2

2 ZnS + 2 O2 > 2 ZnO + SO2

Ca3(PO4)2 + 4 HNO3 > Ca(H2PO4)2 + 2 Ca(NO3)2

2, 3, 2, 2 on the first one.

On the second one, balance the calcium first. See where you get.
