Chemical Reaction Benchmark Review 24-25

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 matter?

Back

The law of conservation of matter states that matter cannot be created or destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting substances in a chemical reaction that undergo change to form products.

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is a simple molecule?

Back

A simple molecule consists of two or more atoms bonded together, typically of the same or different elements, such as H2 or CO2.

Front

What is an extended structure?

Back

An extended structure is a large network of atoms bonded together, such as in diamond or graphite.

Front

How do you calculate the mass of a product in a chemical reaction?

Back

To calculate the mass of a product, use the law of conservation of matter: total mass of reactants = total mass of products.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is one of the reactants in photosynthesis, used by plants to produce glucose.
