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 is the purpose of coefficients in a chemical equation?

Back

Coefficients are used to indicate the number of molecules or moles of a substance involved in a chemical reaction, helping to balance the equation.

Front

What is a subscript in a chemical formula?

Back

A subscript is a small number written to the lower right of an element symbol in a chemical formula, indicating the number of atoms of that element in a molecule.

Front

What are reactants in a chemical equation?

Back

Reactants are the starting substances in a chemical 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

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 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.

Front

What does it mean to balance a chemical equation?

Back

Balancing a chemical equation means adjusting the coefficients to ensure that the number of atoms for each element is the same on both sides.

Front

What is the significance of the number in front of a compound in a chemical equation?

Back

The number in front of a compound (coefficient) indicates how many molecules of that compound are involved in the reaction.

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.
