Based on the chemical equation, the value of coefficient that is used in the reaction is 1.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those equation in which each entities are present in same amount on left side as well as on the right side of the chemical reaction.
Given chemical reaction is:
BaO₂ + H₂SO₄ → H₂O₂ + BaSO₄
Above reaction is balanced as all elements are present in same amount on both sides. So, the value of coefficients is 1.
Hence the required coefficients is 1.
