  1. 3. For chemical reactions to take place, the reacting molecule must do this with enough force to break intermolecular bonds.
  2. 5. This states that mass is neither created nor destroyed.
  3. 6. These are inhibitors used to prevent spoilage of food.
  4. 8. Chemical reactions frequently take place in a series of simple steps called this.
  5. 10. Chemists balance equations using this in front of the formulas of the reactants and products to balance equations.
  6. 11. This is the slowest pathway along a reaction pathway.
  7. 13. A description using chemical symbols and formulas to show the reactants and products in a chemical reaction.
  8. 14. A substance that increases the reaction rate without being permanently changed.
  9. 19. An equation in which the number of atoms of each element on the reactant side is equal to the number of atoms on the product side.
  10. 20. In chemical equations this state is represented by a L.

  1. 1. For chemical reactions to take place, after intermolecular bonds have been broken, these types of atoms must be in the right position to bond with each other.
  2. 2. A measure of the change in concentration of the reactants over a period of time.
  3. 4. Lowering this will decrease a reaction rate while increasing it will increase a reaction rate.
  4. 7. A substance that slows down or stops a chemical reaction.
  5. 9. For a chemical reaction to be accurate, it must contain the correct _______________ of the reactants and products.
  6. 12. In chemical equations if a substance can be dissolved in water it is called this a represented by the letters aq.
  7. 13. A higher level of this in reactants will typically increase a reaction because there is more reactant to react.
  8. 15. In chemical equations this state is represented by a letter s.
  9. 16. area Increasing this, which is done by crushing a reactant into smaller pieces, will increase the reaction rate.
  10. 17. For a chemical equation to be valuable, it must represent the known facts about a reaction. All reactants and products must be this...
  11. 18. In chemical equations this state is represented by a g.
