Balance the given equations:

  1. Cl2 + NaOH → NaCl + NaClO3 + H2O

  2. Zn + NaOH → Na2ZnO2 + H2

  3. MgCO3 + HCl → MgCl2 + H2O + CO2

  4. CaO + P2O5 → Ca3(PO4)2

  5. B2O3 + NaOH → Na3BO3 + H2O

  8. CuSO4 + NaOH → Cu(OH)2 + Na2SO4

  12. PbO2 + HNO3 → Pb(NO3)2 + H2O + O2

  13. SnCl2 + SO2 + HCl → SnCl4 + H2O + S

  14. CuSO4 + KI → Cu2I2 + K2SO4 + I2

  1. 3Cl2 + 6NaOH → 5NaCl + NaClO3 + 3H2O

  2. Zn + 2NaOH → Na2ZnO2 + H2
