- Balance the following:
- Na2S2O3 + HCl →NaCl + H2O + SO2 + S
- NH3 + P2O5 + H2O → (NH4)3PO4
- Mg3N2 + H2O → Mg(OH)2 + NH3
- NH3 + Cl2 → HCl + NCl3
- C + HNO3 → CO2 + H2O + NO2
- S + HNO3 → H2SO4 + H2O + NO2
- Cu + H2SO4 → CuSO4 + H2O + SO2
- FeSO4 + H2SO4 + HNO3 → Fe2(SO4)3 + H2O + NO
- P2O5 + HCl → POCl3 + HPO3
- HNO3 + HCl → NOCl + H2O +[Cl]
