Guided Notes
3 key concepts
- 1
A physical change is a change in the shape or form of matter, like sugar dissolving in water, and it does not create a new substance.
- 2
In a chemical reaction, the substances that react are called reactants, and the new substances that are formed are called products; for example, the ingredients in a cake are the reactants and the baked cake is the product.
- 3
The conservation of mass states that matter is never created or destroyed, but it can change forms, such as when water evaporates or when sugar dissolves in water.
