1. T YPES OF C HEMICAL R EACTIONS

2. S YNTHESIS Synthesis: to join together A + B  AB Mg + O 2  MgO H 2 + O 2  H 2 O

3. D ECOMPOSITION Decomposition: to break apart A B  A + B KClO 3  KCl + O 2 H 2 O 2  H 2 O + O 2

4. S INGLE D ISPLACEMENT Single Displacement: when one element replaces one other element A + BC  B + AC Mg + HCl  H 2 + MgCl 2

5. D OUBLE D ISPLACEMENT Double Displacement: when two elements switch places AB + CD  CB + AD KI + CuNO 3  CuI 2 + KNO 3

6. C OMBUSTION Combustion: When a Carbon based compound (hydrocarbon) combines with Oxygen to make CO 2 and H 2 O CH 4 + O 2  CO 2 + H 2 O
