False
Study Notes
Chemical Reactions
- Reactants are the substances that undergo change in a chemical reaction.
- The Law of Conservation of Mass states that mass is conserved in a chemical reaction, meaning the total mass of the products is always equal to the total mass of the reactants.
- A catalyst is a substance that speeds up a chemical reaction without being consumed in the reaction.
- Chemical reactions involve the breaking and formation of chemical bonds.
- Chemical reactions can occur in various states, not just liquid solutions.
