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 reaction that uses to show the relationship between Reactant and product. |
Reactant | a substance or a molecule that participates in a chemical reaction. |
product | the substance that forms in a chemical reaction. |
Law of conserveation of mass | the law that states that mass cannot be created or destroyed in ordinary chemical and physical change. |
synthesis reaction | a reaction in which two or more substances combine to form a new compound. |
