The equation P + O2 → P2O5 is unbalanced. When balanced, what is the correct coefficient for O2.

The coefficient for O₂ is 5

Explanation:

We are given an unbalanced equation;

P + O₂ → P₂O₅

We are required to balance the equation and determine the coefficient of O₂

We need to know that;

Balancing of chemical equations involves using coefficients to make sure that the number of atoms of each element are equal on both sides of the equation.

To balance the equation given we put coefficients 4, 5, 2

Therefore, the balanced equation is;

4P + 5O₂ → 2P₂O₅

Hence, the coefficient for O₂ is 5

im not exactly sure but i think its b!
