CP Chemistry Term 2 Exam Practice Flashcards

A comprehensive set of vocabulary flashcards covering key terms, reaction types, solution chemistry, and atomic structure based on the CP Chemistry Term 2 study guide.

Acid

A substance where the first element is $H$.

Base

A substance that ends in $OH$.

Coefficient

A whole number placed in front of a formula.

Combustion Reaction

A reaction following the pattern $C_xH_y + O_2 \rightarrow CO_2 + H_2O$.

Decomposition Reaction

A reaction where a compound breaks down, following the pattern $AB \rightarrow A + B$.

Double Replacement

A reaction where elements in two compounds swap, following the pattern $AB + CD \rightarrow AD + CB$.

Endothermic

A process that absorbs heat from its surroundings.

Exothermic

A process that releases heat to its surroundings.

Half-life

The time it takes for half of a sample to decay.

Neutron

A subatomic particle with no charge.

Nucleus

The center of an atom.

Proton

A subatomic particle with a positive charge.

Saturated Solution

A solution containing the maximum amount of solute dissolved.

Single Replacement

A reaction following the pattern $AB + C \rightarrow AC + B$.

Solute

The substance being dissolved; usually the smaller amount.

Solvent

The substance in which the solute is being dissolved; usually the larger amount.

Supersaturated Solution

A solution that contains more than the maximum amount of solute that the solvent can theoretically dissolve.

Synthesis Reaction

A reaction where multiple reactants combine to form one product, following the pattern $A + B \rightarrow AB$.

Unsaturated Solution

A solution containing less than the maximum amount of solute.
