Precipitate | A solid that is produced as a result of a chemical reaction in solution |
Chemical Formula | A combination of chemical symbols and numbers to represent a substance |
Chemical Equation | A representation of a chemical that uses symbols to show the relationship between the reactants |
Reactant | A substance or molecule that participates in a chemical reaction |
Product | A substance that forms in a chemical reaction |
Law of conservation of mass | The law states that mass cannot be created or destroyed in ordinary chemical and physical changes |
Synthesis Reaction | A reaction in which two or more substances combine to form a new compound |
