In the reaction equation P + O2 → P2O5, the coefficient in front of the oxidant formula is.

In this task, it is necessary to determine the coefficient in front of the oxidizer formula. We write down the solution.

First, you should write down the reaction equation and equalize it.

4P + 5O2 = 2P2O5.

When phosphorus interacts with oxygen, the result is phosphorus oxide. The reaction is called a compound reaction.

The oxidizing agent in this reaction is oxygen. The coefficient in front of the oxidizer is 5.

Answer: the coefficient is 5.
