Study Notes
Types of Chemical Reactions
- Decomposition Reaction: A single compound breaks down into two or more simpler substances.
- Double-Displacement Reaction: Ions from two compounds switch places in an aqueous solution to create two new compounds; requires adherence to solubility rules. Involves the replacement of cations and anions.
- Single-Displacement Reaction: One element replaces another element in a compound.
Reaction Mechanisms
- Net Ionic Equation: Represents only the particles directly involved in a chemical change, excluding spectator ions.
- Insoluble and Soluble: Insoluble substances cannot dissolve in a solvent; soluble substances can dissolve (designated as "aq" in equations).
- Aqueous Solution: A solution where water serves as the solvent.
Specific Reaction Types
- Synthesis Reaction: Involves the combination of two or more substances to create a new compound.
- Combustion Reaction: An element or compound reacts with oxygen, generating energy as heat and light; products typically include carbon dioxide (CO2) and water (H2O).
Chemical Principles
- Activity Series: Lists elements in order of decreasing activity; crucial for predicting the viability of single-displacement reactions, especially among halogens: F, Cl, Br, I.
- Law of Conservation of Mass: Mass remains constant during chemical and physical changes; though the number of compounds or molecules may change, the total mass and atomic count do not.
Chemical Products
- Combustion Products of Hydrocarbons: The typical products formed are CO2 and H2O.
- Precipitate: A solid that emerges from a solution during a chemical reaction, noted as (s) in equations.
Other Considerations
- Chemical Equation Symbols: Symbols and formulas used to succinctly represent chemical reactions.
- Reactions Likely Involving Elements: Decomposition and single-replacement reactions typically yield an element as one of the products.
