Chemical Reactions and Equations

Flashcards covering key terms and concepts about chemical reactions and equations.

Chemical Reaction

A process where substances (reactants) undergo a transformation to form new substances (products).

Reactants

Substances that undergo chemical change in a reaction.

Products

New substances formed as a result of a chemical reaction.

Balanced Chemical Equation

An equation where the number of atoms for each element is the same on both sides, in accordance with the law of conservation of mass.

Combination Reaction

A reaction where two or more substances combine to form a single product.

Decomposition Reaction

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

Displacement Reaction

A reaction in which one element displaces another in a compound.

Double Displacement Reaction

A reaction in which two compounds exchange ions to form two new compounds.

Exothermic Reaction

A chemical reaction that releases heat to the surroundings.

Endothermic Reaction

A chemical reaction that absorbs heat from the surroundings.

Oxidation

A process where a substance gains oxygen or loses hydrogen during a reaction.

Reduction

A process where a substance loses oxygen or gains hydrogen during a reaction.

Corrosion

The gradual destruction of materials (usually metals) by chemical interactions with their environment.

Rancidity

The process where fats and oils become spoiled due to oxidation, resulting in off-smells and tastes.
