Question

Balance the following chemical equation:

d) <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> ${Na}_{2}O$ + <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $H_{2}O$ → $NaOH$

Answer 1

The skeletal equation is:

${Na}_{2}O$ + <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $H_{2}O$ → $NaOH$

• Count the number of atoms of each element.

• To equalize Na, O and H multiply NaOH by 2

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> ${Na}_{2}O$ + <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $H_{2}O$ → 2$NaOH$

Hence, the equation is balanced.
