Chemical Reactions

4. The amount of a substance in a solution
6. A process in which a substance undergoes a change in its atomic or molecular structure and becomes a new substance.
8. When particles meet with enough energy required for chemical reaction to occur.
10. Any chemicals that are formed as a result of a chemical reaction.
11. The amount of area of a substance exposed to a chemical reaction.
13. A sub-atomic particle found in the nucleus of an atom with a positive charge.
14. How fast a reaction occurs, measuring by how quickly a reactant or product changes over time.
15. A sub-atomic particle with a negative charge and a very small mass found in orbitals around the nucleus of an atom.
16. A sub-atomic particle found in the nucleus of an atom with no charge.

1. A chemical that increases the rate of a reaction by lowering the activation energy but is not used up in the reaction.
2. A way of representing how the electrons within an atom or ion are arranged.
3. Any chemicals that are rearranged during a chemical reaction.
5. Value used to describe the amount of thermal energy in a substance. Can increase the rate of reactions.
7. Charged chemicals formed when an atom (or group of atoms) loses or gains electrons.
9. The amount of force across the surface area of the volume of a substance.
12. The minimum amount of energy needed for a chemical reaction to occur.
