Study Notes
Chemical Equations
- Chemical equations consist of reactants on the left side and products on the right side.
Stoichiometry Types
- Equation Stoichiometry: Focuses on quantitative relationships between reactants and products involved in a chemical change.
- Formula Stoichiometry: Examines quantitative relationships among elements within a chemical compound.
Reaction Types
- Synthesis: Involves the combination of two or more substances to create a single compound; yields one product.
- Decomposition: A single compound breaks down into two or more simpler substances; involves only one reactant.
- Single Replacement: One element displaces another within a compound, involving either metal-for-metal or nonmetal-for-nonmetal replacement.
- Double Replacement: Involves an exchange of ions between two compounds, with cations swapping with anions.
- Combustion: The process of burning a substance in the presence of oxygen (O2), which typically results in carbon dioxide (CO2) and water (H2O) from hydrocarbons.
Key Concepts
- Stoichiometry: Similar to a recipe, it allows chemists to calculate relationships between reactants and products in chemical reactions.
- Percent Yield: Measures the efficiency of a reaction, comparing the actual amount of product obtained to the theoretical yield; calculated using the formula: % yield = (actual mass / theoretical mass) x 100.
- Limiting Reactant: Defined as the reactant that is completely consumed in a reaction, thus limiting the amount of product produced.
- Excess Reactant: Refers to any reactant that remains unreacted after the chemical reaction has completed.
