Study Notes
Types of Chemical Reactions
- Chemical reactions can be predicted based on reactants and conditions.
- Combination Reaction: Involves two or more elements and/or compounds combining to form a single product.
- Decomposition Reaction: A single compound is broken down into simpler substances.
- Single Replacement Reaction: One element replaces another in a compound; involves an element and a compound.
- Double Replacement Reaction: Involves the exchange of ions between two compounds, typically occurring in an aqueous solution.
Activity Series
- The activity series of metals helps predict the feasibility of single-replacement reactions.
Combustion Reaction
- Combustion reactions involve a compound reacting with oxygen, producing energy.
- Complete combustion of hydrocarbons results in carbon dioxide (CO2) and water (H2O).
- Example: Combustion of hexane (C6H14) yields CO2 and H2O.
Gas Production
- In double-replacement reactions, one product may be a gas that bubbles out of the mixture.
Replacement Reactions
- Nonmetals can replace other nonmetals within compounds during single-replacement reactions.
