Answer

Explanation:

Step1: Analyze hydrogen - peroxide formula

The formula of hydrogen peroxide is $H_2O_2$, which means 1 molecule of $H_2O_2$ has 2 hydrogen (H) atoms and 2 oxygen (O) atoms.

Step2: Count total H and O atoms in products

In the products, we have 1 molecule of $O_2$ (2 O atoms) and 2 molecules of $H_2O$ (4 H atoms and 2 O atoms). So in total, there are 4 H atoms and 4 O atoms in the products.

Step3: Determine number of $H_2O_2$ molecules

Since 1 molecule of $H_2O_2$ has 2 H and 2 O atoms, to get 4 H and 4 O atoms in the products, the number of $H_2O_2$ molecules reacting is 2. Because $2\times2 = 4$ for both H and O atoms from $2H_2O_2$.
