Kinetic Theory
a) A substance made up of two or more different elements that are chemically joined in fixed proportions.
b) The theory that states that as the temperature rises, particles move faster and therefore take up more space.

What is the Law of Constant Composition?

b) A pure compound always contains the same elements in the same proportions.
c) The pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases.
d) None of the above
Redox reaction
a) A reaction that primarily involves the transfer of electrons between two substances.
b) A substance which speeds up a chemical reaction without being changed by the reaction.
c) A substance made up of one type of atom, which cannot be broken down by chemical reaction to form a simpler substance.
