Where are coefficients placed while balancing a chemical equation?

Answer and explanation

Correct answer: Before the chemical formulae

To balance a chemical equation, coefficients are placed before chemical formulae. For example, in \(2H_2 + O_2 \rightarrow 2H_2O\), 2 is a coefficient and shows the number of molecules. Subscripts inside a formula, such as 2 in \(H_2\), must not be changed because doing so changes the formula and identity of the substance.
