How does a balanced chemical equation demonstrate the law of conservation of mass?
Answer and explanation
Correct answer: The number of atoms of each element is the same on both sides of the equation.
According to the law of conservation of mass, atoms are neither created nor destroyed in a chemical reaction. In a balanced equation, the number of atoms of every element is the same on the reactant and product sides; therefore, total mass is conserved. Reactants and products need not have the same colour or physical state, so options A, C, and D are incorrect.
