Questions & Step-by-Step Solutions
Which of the following is a correct statement about the law of conservation of mass?
Correct Answer: Mass is neither created nor destroyed.
Step 1: Understand what the law of conservation of mass means. It tells us that in a chemical reaction, the total mass of the substances involved does not change.
Step 2: Recognize that this means that the mass of the reactants (the starting materials) will equal the mass of the products (the substances formed) after the reaction.
Step 3: Remember that mass cannot be created or destroyed; it can only change forms or be rearranged during a chemical reaction.
