Reactant?
A molecule or substance that participates in a chemical reaction.
Product?
A substance that is made in a chemical reaction.
Chemical Energy?
The energy let out when a chemical compound reacts to make new compounds.
Exothermic Reaction?
A chemical reaction where heat is let out to the outside.
Endothermic Reaction?
A chemical reaction that takes heat.
Synthesis Reaction?
A reaction where 2 or more substances combine to make a new compound.
Decomposition Reaction?
A reaction where a compound breaks down to make 2 or more simpler substances.
Electrolysis?
A process where an electric current is used to make a chemical reaction, such as the decomposition of water.
Combustion Reaction?
The oxidation reaction of an organic compound, in which heat is let out.
Single-Displacement Reaction?
A reaction in which one element or radical takes the spot of another element or radical in a compound.
Double-Displacement Reaction?
A reaction where a gas, a solid precipitate, or a molecular compound is made from the apparent exchange of atoms or ions between 2 compounds.
Oxidation-Reduction Reaction?
Chemical reaction where one species loses electrons and another gains electrons.
Radical?
Organic group that has one or more electrons ready for bonding.
Reduced?
.
Oxidized?
Losing electrons
Chemical Equation?
A representation of a chemical reaction that requires symbols to show the relationship between the reactants and the products.
Mole Ratio?
The relative number of moles of the substances used to produce a given amount of product in a chemical equation.
Catalyst?
A substance that changes the rate of a chemical reaction without being consumed or changed significantly.
Enzyme?
A type of protein that speeds up metabolic reactions in plants and animals without being changed or destroyed.
Substrate?
A part, substance, or element that lies under and supports another part, substance, or element.
Chemical Equilibrium?
A state of balance where the rate of a forward reaction is the same as the rate of the reverse reaction and the concentrations of products and reactants remain unchanged.
