2.  A chemical reaction changes the properties and energy of the old substances into a new substance.  A chemical reaction involves a rearrangement of atoms.  Chemical Equations : Show Changes that take place in a chemical reaction.  EXAMPLE : AgNO 3 (aq)+ NaCl (aq)  AgCl(s) + NaNO 3 (aq) Reactants Yield Products  Reactants : The chemicals you start with  Products : The chemicals you end up with  Conservation of Mass : You must have the same amount of each element at the beginning and the end of a reaction. Elements cannot appear or disappear!

4. “Getting Together” Girl A + Boy B  Couple AB

5. A + B  AB Examples: 2 H 2 + O 2  2 H 2 O SO 3 + H 2 O  H 2 SO 4

6. “Breaking Up” Couple AB  Girl A + Boy B

7. AB  A + B Examples: 2 KClO 3  2 KCl + 3 O 2 2 H 2 O  2 H 2 + O 2

8. “Couple/Single Switcheroo” Couple AB + Boy C  Couple AC + Boy B

9. A + BC  AC + B Examples: Zn + Cu(NO 3 ) 2  Zn(NO 3 ) 2 + Cu

10. “Couple/Couple Switcheroo” Couple AB + Couple CD  Couple AD + Couple CB

11. AB + CD  AD + CB Examples: AgNO 3 + NaCl  AgCl + NaNO 3

12. A combustible material + oxygen → carbon dioxide + water + energy

13. C 10 H 8 + 12 O 2 → 10 CO 2 + 4 H 2 O
