FLASHCARD QUESTION

Front

What is an unbalanced chemical equation?

Back

An unbalanced chemical equation does not have the same number of each type of atom on both sides, meaning that mass is not conserved in the representation of the reaction.

FLASHCARD QUESTION

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction; it can only change forms.
