Guided Notes
Key concepts students will learn:
- •
In a chemical reaction, new substances are created due to the rearrangement of atoms.
- •
The substances present before a chemical reaction are called reactants, while the substances produced after the reaction are called products.
- •
During a chemical reaction, the mass of the reactants and the mass of the products are the same because atoms are only being rearranged, not created or destroyed.
