Which one of the following statements about balanced equations is true? A reaction is balanced by
A)changing the charge on an ion.
B)changing the formula of the molecule.
C)multiplying by suitable coefficients.
D)rearranging atoms in a molecule.

Question

Quizplus · Accepted Answer

A balanced equation must have the same number of atoms of each element on both sides of the reaction arrow. This is achieved by multiplying the coefficients before each molecule/compound in the equation. Changing the charge on an ion, changing the formula of a molecule, or rearranging atoms in a molecule would all result in a different chemical reaction, not a balanced one.
