Chemical Reactions Overview

Flashcards covering key concepts related to chemical reactions as outlined in the lecture notes.

Chemical reaction

A process where bonds between reactant particles are broken and new bonds are formed in the products.

Synthesis reaction

A type of chemical reaction where two or more reactants combine to form a single product.

Decomposition reaction

A chemical reaction where a single compound breaks down into two or more simpler substances.

Displacement reaction

A reaction in which one element takes the place of another in a compound.

Precipitation reaction

A chemical reaction that occurs when two soluble substances form an insoluble substance or precipitate.

Conservation of mass

The principle stating that mass is neither created nor destroyed in a chemical reaction; the number of atoms remains constant.

Reactant

Substances that undergo change in a chemical reaction.

Product

Substances that are formed as a result of a chemical reaction.

Catalyst

A substance that speeds up a chemical reaction without being consumed in the process.

Exothermic reaction

A chemical reaction that releases energy in the form of heat.

Endothermic reaction

A chemical reaction that absorbs energy from its surroundings.

Oxidation

A process in which a substance loses electrons, often associated with the addition of oxygen or the removal of hydrogen.

Reduction

A process in which a substance gains electrons, often associated with the removal of oxygen or the addition of hydrogen.
