Solve the chemical reaction equation P + O2 =

4P + 5O2 = 2P2O5
For the reaction to be spelled correctly, you need to equalize. We put 2 in front of phosphorus oxide, it turns out on the right 4 phosphorus and 10 oxygen. Then on the left in front of phosphorus we put 4, in front of oxygen we put 5. Checking. Left 4 phosphorus, 10 oxygen. On the right there are 4 phosphorus, 10 oxygen.
