The amount of oxygen in the reactants is 4 atoms. in the products, the oxygen is distributed to water (h2o) and o2 gas. which coefficients would be placed in front of water and oxygen? 2 in front of water and 2 in front of oxygen 1 in front of water and 2 in front of oxygen 1 in front of water and 1 in front of oxygen 2 in front of water and 1 in front of oxygen

Option (d) is the correct answer.

Explanation:

To balance a chemical equation it is necessary that the total number of reactant molecules equal the total number of products.

It is given that amount of oxygen atoms on reactant side is 4.

There is formation of and which means that without balancing the equation, total number of oxygen atoms on product side is 3.

Therefore, to balance the equation multiply by 2 and by 1. Thus, now there will be total 4 atoms on the product side.

Hence, we can conclude that the coefficient 2 should be placed in front of water and 1 in front of oxygen.
