Study Notes
Types of Chemical Reactions
- Combination reaction: A + B → C
- Decomposition reaction: C → A + B
- Combustion reaction: Fuel + oxygen → carbon dioxide and water
- Involves a fuel (often a hydrocarbon) reacting with oxygen
- Produces carbon dioxide and water
- Single Replacement reaction: AB + C → AC + B
- Double Replacement reaction: AB + CD → AD + CB
- Neutralization reaction: HA + MOH → MA + H₂O
Combustion Reaction
- Example: CH₄ + 2O₂ → CO₂ + 2H₂O
- Definition: A reaction in which a compound reacts with oxygen molecules
- Typically involves fuels, which are often hydrocarbons
- Produces carbon dioxide and water
Decomposition Reaction
- Definition: A reaction in which one compound breaks down into two or more compounds
- Opposite of a synthesis reaction, where two or more reactants form one compound
