  1. 4. This process happens when an acid and a base react to form water and a salt and it involves the combination of H+ ions and OH- ions to generate water.
  2. 5. They can be used to represent chemical reactions.
  3. 7. The law of conservation of matter states that matter is neither-------during a chemical reaction.
  4. 10. This is what we call a reaction in which energy is given off with the products, usually in the form of heat or light.
  5. 12. This is what we call the substances produced at the end of a chemical reaction.
  6. 13. These compounds contain linked carbon atoms that form bonds with other atoms, usually hydrogen, oxygen, nitrogen, and/or sulfur.
  7. 14. This is the amount of energy needed to get a reaction going.

  1. 1. Because of the law of conservation of mass, a chemical equation must------.
  2. 2. To balance a chemical equation, you CANNOT change the ------ of any reactant or product.
  3. 3. This is what we call the substances that go into a chemical reaction.
  4. 6. The neutralization of a strong acid and strong base has a pH equal to this number.
  5. 8. This is involved in ALL chemical reactions.
  6. 9. To balance a chemical equation, you can change the ----------, which is the number of units of any reactant or product.
  7. 11. This what we call a reaction in which the reactants absorb energy from their surroundings is an endothermic reaction.
