1. Types of Reactions

2. Addition Reactions A + B  AB H 2 + O 2  H 2 O

3. Decomposition Reaction This is the reverse of the addition reaction. A molecule will break apart into components. AB  A + B 2 H 2 O 2  H 2 O + O 2 C 11 H 22 O 11  C + 11 H 2 O 2 H 2 O  H 2 + O 2

4. before after Single-Displacement Reaction A n X + y B  B y X+ n A 3 CuCl 2 + 2 Fe  FeCl 3 + 3 Cu Recall the copper coating the nail in the metal reactivity lab.

5. Double-Displacement Reaction AB + CD  AD+ CB H 2 SO 4 + 2 NaOH  Na 2 SO 4 + 2 HOH

6. Combustion Reaction C x H y O z + X O 2  X  CO 2 + Z H 2 O C 11 H 22 O 11 + 11 O 2  CO 2 + 11 H 2 O
