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.
