Question

Balance the following chemical equation:
c) <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $H_2$ + <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $O_2$ → <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $H_2$O

Answer 1

The skeletal equation is:

$H_2$ + <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $O_2$ → <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $H_2$O

• Count the number of atoms of each element.

• To equalize O, multiply $H_2$O by 2

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $H_2$ + <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $O_2$ → 2 <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $H_2$O

• To equalize H, multiply $H_2$ by 2

2$H_2$ + <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $O_2$ → 2 <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $H_2$O

Hence, the equation is balanced
