The energy that is released by to substances during a chemical reaction.

When heat is released during a chemical reaction.

A chemical reaction that needs heat to change

When two or more substances come together to make a new compound.

When a compound breaks down and makes simpler substances.

When a electric current is used to make a chemical reaction.

When oxygen is used to make a reaction of a compound and heat is released.

One element takes the place of another element in a compound.

A reaction that occurs when a gas, solid, or a molecular compound forms from the exchange of atoms or ions.

A chemical reaction when electrons are transferred.

A organic group that has more one or more electrons available for bonding.

When oxygen is lost or hydrogen is gained.they accept electrons.

Substances that give up their electrons.

Equation used to show the relationship between reactants and the products.

Relative number of moles in a substance.

Numbers in front of the chemical formulas.

The total mass of reactants is always the same as the total mass of the product.

A compound always contains the same elements in the same proportions.

Substance that changes the chemical reaction without being changed.

Protein that speeds up metabolic reactions without being changed or destroyed.

Part of a substance that lies beneath and supports another substance.

The rate of forward relations is equal to the rare of the reverse action. The concentrations and reactants remain uncharged.
