Which of the following statements is true for a balanced chemical equation?

Correct option is C

Correct Answer: (C) The total number of atoms of each element is the same on both sides.

Explanation:
In a balanced chemical equation, the law of conservation of mass applies, which states that matter cannot be created or destroyed in a chemical reaction. Therefore, the total number of atoms of each element is conserved and remains the same on both sides of the equation.

• The total number of moles is the same on both sides: This is incorrect. The number of moles may differ between the reactants and products, depending on the stoichiometric coefficients.

• The total mass of molecules is unequal on both sides: This is incorrect. The total mass of the reactants must equal the total mass of the products, in accordance with the law of conservation of mass.

• The total number of molecules is the same on both sides: This is incorrect. The number of molecules does not have to be the same on both sides; the coefficients of the chemical equation can differ.

  Thus, the correct statement is that the total number of atoms of each element is the same on both sides.
