Balancing Chemical Equations

Front

What is the product side of a chemical equation?

Back

The product side is the right side of a chemical equation, which shows the substances formed as a result of the reaction.

Front

What is the purpose of balancing chemical equations?

Back

Balancing chemical equations ensures that the number of atoms for each element is the same on both sides of the equation, adhering to the law of conservation of mass.

Front

What does the law of conservation of mass state?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.

Front

What is a reactant in a chemical equation?

Back

A reactant is a substance that undergoes a chemical change in a reaction, found on the left side of the equation.

Front

What is a product in a chemical equation?

Back

A product is a substance that is formed as a result of a chemical reaction, found on the right side of the equation.

Front

What is the significance of the yields sign (→) in a chemical equation?

Back

The yields sign indicates the direction of the reaction, separating reactants from products.
