Question

types of chemical reactions
the total number of oxygen atoms in the reactants in this equation is____.
4 8 2

Explanation:

Step1: Analyze reactants

The reactant is \(2H_2O_2\).

Step2: Calculate oxygen atoms

In \(H_2O_2\), there are 2 oxygen atoms per molecule. With 2 molecules (\(2H_2O_2\)), the total number of oxygen atoms is \(2\times2 = 4\).

Answer:

4
