1. Types of Reactions

2. Combustion
Reactions that have hydrocarbons (CH4) and oxygen as reactants, and carbon dioxide and water as products.

3. Example:
C3H8 + 5O2  3CO H2O

4. Synthesis Reactions

5. Synthesis

6. Examples
2Na + Cl NaCl
Na2O + CO Na2CO3

7. Decomposition Reactions
Starts with one reactant and ends with 2 or more products.

8. Decomposition

9. Examples
2KClO KCl +3O2
2NaCl Na + Cl2

10. Single Replacement
Reactions
One compound and a free element that recombine to yield a new compound and new free element.

11. Single Replacement

12. Examples
Fe+CuSO4 Cu +FeSO4
2Na + 2HCl H2 +2NaCl

13. Double Replacement
Reactions
Starts with 2 compounds as reactants. These recombine to form 2 new compounds as products.

14. Double Replacement

15. NaCl + AgNO3 NaNO3 + AgCl KOH + HNO3 HOH + KNO3 Examples
