Question

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?

Answer 1

Given - The amount of oxygen in the reactants is 4 atoms.

Find - Coefficients that would be placed in front of water and oxygen

Solution - The number of atoms in a reaction, on both sides namely reactants and products remains the same.

As per given information, there are four atoms on reactant side, so there will be four atoms on product side. There are two atoms in oxygen gas and one atom in water molecule. So there will be two molecules of water to equate the number of oxygen atoms.

Hence, there will be two molecules of water and one molecule of oxygen. The coefficients will be 2 and 1 for water and oxygen respectively.
