chemical property

indicates how a substance reacts with something else, matter will be changed into a new substance after the reaction

14

physical change

a change of matter from one form to another without a change in chemical properties

18
New cards

chemical change

A change that occurs when one or more substances change into new substances with different properties.

19
New cards

physical change examples

New cards

Law of Conservation of Matter

matter cannot be created or destroyed

22

mass of reactants = mass of products

The reactants that went into the making of the product have the same mass as the actual product once its made since matter cannot be destroyed or created.
