FLASHCARD QUESTION

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, indicating that mass is conserved during the reaction.

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.

FLASHCARD QUESTION

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure that the number of atoms of each element is the same on both sides.

5.

FLASHCARD QUESTION

Front

What is a coefficient in a chemical equation?

Back

A coefficient is a number placed in front of a chemical formula in an equation to indicate how many molecules or moles of that substance are involved in the reaction.

FLASHCARD QUESTION

Front

What is the significance of the coefficients in a balanced equation?

Back

Coefficients indicate the relative amounts of reactants and products involved in a chemical reaction, reflecting the ratios in which they react and are produced.

FLASHCARD QUESTION

Front

What is the difference between reactants and products in a chemical reaction?

Back

Reactants are the starting substances that undergo a chemical change, while products are the substances formed as a result of the reaction.
