1. Types of Chemical Reactions

2. Synthesis Reaction: Magnesium + Oxygen

3. Single Displacement Reaction: Zinc + Hydrogen Chloride

4. Double Displacement Reaction: Silver nitrate + Sodium Chloride

5. H2O2H2O2 Decomposition Reaction: Water  Hydrogen + Oxygen

6. Explanation Carbon electrode

7. Combustion / Oxidation Reaction Combustion: Hydrocarbon + oxygen  CO 2 + H 2 O Example: Methane + oxygen  CO 2 + H 2 O CH 4 + 2 O 2  CO 2 + 2 H 2 O Oxidation: 4 Fe + 3 O 2  2 Fe 2 O 3 (rust) In both reactions, oxygen is a reactant and oxide is a product.
