Question

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

Answer 1

2H2 + O2 goes to 2H2O

Answer 2

Step-by-step 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`
