Balancing Chemical Equations

A collection of vocabulary flashcards that cover key concepts related to balancing chemical equations and the principles of chemical reactions.

Balancing Chemical Equations

The process of ensuring that there are equal numbers of each element's atoms on both sides of a chemical equation.

Reactants

The substances present before a chemical reaction takes place.

Products

The substances produced after a chemical reaction occurs.

Law of Conservation of Mass

A principle stating that mass is neither created nor destroyed in a chemical reaction; it only changes forms.

Chemical Change

A process where the composition of a substance changes due to the breaking and forming of chemical bonds.

Physical Change

A transformation that affects the form of a chemical substance, but not its chemical composition.

Balanced Chemical Equation

A chemical equation in which the number of each type of atom on the reactant side equals the number of each type of atom on the product side.

Chemical Reaction
