Product
Substance that forms in a chemical reaction
Reactant
A substances or molecule that participates in any chemical reaction
Chemical energy
Energy that is released from when a compound reacts to produce new compounds
Exothermic reaction
Chemical reaction is when he is released from its surroundings Example- when burning a candle
Endothermic reaction
Chemical reaction that requires heat Example a camp fire requires a match to get it started
Synthesis reaction
Two or more substances combine to form a new compound
Decomposition reaction
When a compound breaks down to form two or more simpler substances
Electrolysis
When an electric current is used to produce chemical reaction .
Combustion reaction
Reaction of an organic compound when heat is released
Single displacement reaction
When a reaction of one elect takes place of another element
Double displacement reaction
When a solid precipitates or a molecular compund forms the apparent change of atoms or ions between two compounds
Oxidation reduction reaction
When one species loses electrons and when another species gains electrons
Radical
An organic group that can bond one or more electrons
Reduced
Substances that accept electrons
Oxidized
Substances that give up electrons
Chemical equation
A chemical reaction that uses symbols to show the relationship between the reactants and products
Mole ratio
Number of moles the substances needs to produce a given amount of product in a chemical reaction
Coefficient
A number that is placed before or after the formula
Law of conservation of mass
Not created or destroyed by chemical or physical transformations
Law of definite properties
Chemical compound contains exactly the same proportions as as the elements mass
Catalyst
Changed the rate of a chemical reaction without being changed
Enzyme
Protein that speeds up metabolic reactions in plants and animals
Substrate
Substances that lie beneath and supports another part substance or element
Chemical equilibrium
Rate of the forward reaction equals the rate of the reverse action
