Question

Fill in the coefficients that will balance the following reaction: a0H2 + a1O2 → a2H2O

Answer 1

2H2 + O2 goes to 2H2O

Answer 2

Explanation:

The given equation is as follows.

       $H_{2} + O_{2} \rightarrow 2H_{2}O$

Number of reactant atoms are as follows.

• H = 2
• O = 2

Number of product atoms are as follows.

• H = 4
• O = 2

Thus, in order to balance the given equation, multiply $H_{2}$ by 2 and $O_{2}$ by 1. Therefore, the balanced equation is as follows.

           $2H_{2} + O_{2} \rightarrow 2H_{2}O$
