A process in which two or moresubstancesreact with oneanother to form one or more different substances
Chemical reaction
It is a process in which the law of conservation of mass applies
During a chemical reaction, atoms are rearranged
What's in a reaction?
Reactants (starting materials)
Products (substances formed as a result of the reaction)
Chemicalequation
A chemist's shorthand for a chemical reaction
Shows the symbols or formulas of the reactants and products, the phases (solid, liquid, gas) of these substances, and the ratio of the substances as they react
Law of conservation of mass
States that the mass of the reactants and the mass of the products must be balanced
