NaCl + H2O → NaOH + Cl2 + H2 Balance the equation. Choose "blank" if no coefficient is needed. NaCl + H2O → NaOH + Cl2 + + H2

The balanced equation is:

2NaCl + 2 H2o → 2 NaOH + Cl2 + H2

1 - we put 2 NaCl to balance Cl2 on the other side.

2 - we put 2 NaOH to balance Na

3 - We put 2 H2O to balance H & O on the to sides
