Define a chemical equation
an expression that describes a chemical reaction using chemical formulas and other symbols
Define an element
matter in which all atoms are alike. Cannot be broken down any further and retain its original properties
Define a compound
matter that is a combination of 2+ different atoms that are chemically combines, can be chemically broken down into elements
Define a mixture
a material made up of 2+ substances which are not chemically combined, can be seperated by physical means
