The equation p + o2 → p2o5 is unbalanced. when balanced, what is the correct coefficient for o2?

Answer : The correct coefficient for is, 5

Explanation :

The given unbalanced chemical reaction is,

According to the balanced chemical reaction, the number of different atoms of elements present on the reactant side should be equal to the the product side.

The balanced chemical reaction will be,

By the stoichiometry we can say that, 4 moles of phosphorous react with 5 moles of oxygen to give 2 moles of diphosphorous pentoxide as a product.

From the balanced chemical reaction, we conclude that the correct coefficient for is, 5

Hence, the correct coefficient for is, 5
