eight
four
one
two

Explanation:

Step1: Count hydrogen atoms on the left - hand side

On the left - hand side, in \(CH_4\), the number of hydrogen atoms is \(4\).

Step2: Balance hydrogen atoms

Since each \(H_2O\) molecule has \(2\) hydrogen atoms. Let the coefficient of \(H_2O\) be \(x\). Then \(2x = 4\) (from hydrogen atom balance). Solving for \(x\), we get \(x = 2\).

Answer:

two
