100
The ability or inability of a substance to combine with or change into one or more new substances.
What is a Chemical property?
100
In chemical reactions this is either absorbed or released.
What is energy?
100
The number in front of the reactant or product that tells how many atoms, molecules, or formula units are in a reaction.
What is a coefficient?
100

Molecules that contain two atoms.

What is a Diatomic molecule?

100

Energy cannot be created or destroyed, simply changed from one form to another.

What is the Law of conservation of energy?

200
A change from one substance into another substance.
What is a Chemical change?
200
The total mass before a chemical reaction is equal to the total mass after the reaction.
What is the Law of conservation of mass?
200
An equation with the same number of atoms of each element on both sides.
What is a Balanced equation?
200

A molecule composed of two or more different elements.

What is a compound?

200

A process that releases energy.

What is Exothermic?
