What is done to balance a skeletal chemical equation?

Answer and explanation

Correct answer: Suitable coefficients are placed before the chemical formulae without changing them.

Balancing a skeletal equation means making the number of atoms of every element equal on both sides while preserving the identities of the substances. This is done by adding suitable whole-number coefficients before formulae, such as changing H₂ + O₂ → H₂O to 2H₂ + O₂ → 2H₂O. Subscripts must not be altered because that would create different substances. Hence A is correct.
