Why is it incorrect to change the subscripts in a chemical formula while balancing a chemical equation?

Answer and explanation

Correct answer: The chemical identity and formula of the substance change.

Subscripts specify the fixed number of atoms of each element in a compound. For example, changing H₂O to H₂O₂ changes water into hydrogen peroxide, so it changes the substance itself. Only coefficients should be changed when balancing because they change the number of molecules or moles without changing the chemical formula.
