I2
Cl2
Br2
energy stored in chemical bonds of a substance. The kinds of atoms and the arrangement of atoms determine the amount of energy stored in a substance
Chemical potential energy
bonds are broken when molecules collide with enough energy
Collision theory
– a chemical reaction in which a fuel burns in a gas, usually oxygen.
Combustion
a scientific law that states that the total amount of matter in a closed system remains constant /
Conservation of matter
a chemical reaction in which a single substance is broken down into two or more products.
Decomposition
cause a substance to be deposited in solid form from a solution
Precipitate
chemical equation that does not indicate the relative amounts of the reactants and products
Skeletal equation
