Balance the reaction. A coefficient of "1" is understood. Choose option "blank" for the correct answer if the coefficient is "1." H₂O₂ → H₂O + O₂

2H₂O₂ → 2H₂O + O₂

Explanation:

H₂O₂ → H₂O + O₂

The above equation can be balance as illustrated below:

H₂O₂ → H₂O + O₂

There are 2 atoms of O on the left side and a total of 3 atoms on the right side. It can be balance by putting 2 in front of H₂O₂ and 2 in front of H₂O as shown below:

2H₂O₂ → 2H₂O + O₂

Now, the equation is balanced.
