Chemical Reactions and Balancing Equations

Flashcards on chemical changes, balanced reactions, and equations related to chemical reactions.

Chemical Change

A change that occurs when two clear aqueous solutions mix to form a cloudy yellow solid.

Balanced Chemical Reaction

A reaction is balanced when the same number of each kind of atom appears in the reactants and products.

(aq)

The symbol for a substance in an aqueous solution.

Balancing Coefficients

Coefficients of the reactants should be equal to the coefficients of the products for a balanced equation.
