Balancing Equations Bell Ringer

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 Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that matter cannot be created or destroyed in a chemical reaction; it can only change forms.

Front

What are the two sides of a chemical equation called?

Back

The two sides of a chemical equation are called Reactants (left side) and Products (right side).

Front

How do you balance a chemical equation?

Back

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

Front

What is a subscript in a chemical formula?

Back

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

Front

What is the purpose of balancing chemical equations?

Back

The purpose of balancing chemical equations is to ensure that the Law of Conservation of Mass is upheld, showing that the same amount of matter exists before and after a reaction.

Front

What does the coefficient in a chemical equation represent?

Back

A coefficient in a chemical equation represents the number of molecules or moles of a substance involved in the reaction.

Front

What is the difference between reactants and products?

Back

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

Front

What is the significance of balancing equations in real-world applications?

Back

Balancing equations is crucial in real-world applications such as chemical manufacturing, environmental science, and pharmacology, where precise amounts of reactants and products are necessary.

Front

What is the first step in balancing a chemical equation?

Back

The first step in balancing a chemical equation is to write down the unbalanced equation and count the number of atoms of each element on both sides.
