Balancing Chemical Equations

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.

Front

What does the coefficient in a chemical equation represent?

Back

The coefficient indicates the number of molecules or moles of a substance involved in the reaction.

Front

What is the Law of Conservation of Mass?

Back

It states that matter cannot be created or destroyed in a chemical reaction.

Front

What are reactants in a chemical equation?

Back

Reactants are the substances that undergo a chemical change in a reaction, found on the left side of the equation.

Front

What are products in a chemical equation?

Back

Products are the substances formed as a result of a chemical reaction, found on the right side of the equation.

Front

What is a subscript in a chemical formula?

Back

A subscript is a small number written after an element symbol that indicates the number of atoms of that element in a molecule.

Front

How do you determine if a chemical equation is balanced?

Back

Count the number of atoms of each element on both sides of the equation; if they are equal, the equation is balanced.

Front

What is the difference between a coefficient and a subscript?

Back

A coefficient indicates the number of molecules, while a subscript indicates the number of atoms in a molecule.

Front

What is the purpose of balancing chemical equations?

Back

Balancing chemical equations ensures that the Law of Conservation of Mass is upheld, showing that matter is neither created nor destroyed.

Front

What does it mean if a chemical equation is unbalanced?

Back

An unbalanced equation indicates that the number of atoms of at least one element is different on the reactant and product sides.
