Chemical Reactions Overview

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.
