Study Notes
Combustion Reaction
- Occurs when a substance reacts with oxygen.
- Produces energy in the form of heat and light.
Synthesis Reaction
- Involves two or more substances combining.
- Results in the formation of a different substance.
Decomposition Reaction
- One substance breaks down into two or more simpler substances.
- Often requires energy, such as heat, to initiate.
Single-Displacement Reaction
- Features one element replacing another in a compound.
- Typically involves an element and a compound reacting together.
Double-Displacement Reaction
- Involves two ionic compounds in solution.
- Can produce a precipitate, water, or a gas as a reaction product.
Precipitate
- An insoluble compound formed during a double-displacement reaction.
- Indicates a chemical change has occurred in the solution.
Oxidation
- Characterized by the loss of electrons from a substance's atoms.
- Plays a crucial role in many chemical reactions, particularly combustion.
Reduction
- Involves the gain of electrons by a substance's atoms.
- Often occurs alongside oxidation in redox (reduction-oxidation) reactions.
