Answer

Answer:

2

Explanation:

Step1: Analyze hydrogen atoms

In $H_2O_2$, there are 2 hydrogen atoms per molecule. In the products, there are 4 hydrogen atoms from 2 molecules of $H_2O$ (since each $H_2O$ has 2 hydrogen atoms). Let the number of $H_2O_2$ molecules be $x$. The number of hydrogen atoms from $H_2O_2$ is $2x$. So, $2x = 4$.

Step2: Solve for $x$

Dividing both sides of the equation $2x = 4$ by 2, we get $x=\frac{4}{2}=2$.
