In an unbalanced equation, oxygen atoms are fewer on the right side. What is the most correct method during balancing?

Answer and explanation

Correct answer: Placing suitable coefficients

Balancing a chemical equation means making the number of atoms of each element equal on both sides while keeping the identities of the substances unchanged. This is done by placing suitable whole-number coefficients before chemical formulae. Changing a subscript changes the substance itself, and removing a reactant or reversing the arrow changes the reaction rather than balancing it. Therefore, option B is the correct method.
