Reactants VS. Products

Front

What does the law of conservation of mass state about matter during a chemical reaction?

Back

Matter cannot be created or destroyed during a chemical reaction.

Front

True or False: The products of a chemical reaction must contain the same type of elements as the reactants.

Back

True

Front

What type of reaction occurs when energy is released, such as when burning Cheetos?

Back

Exergonic reaction.

Front

What are the starting materials in a chemical reaction called?

Back

Reactants.

Front

What are the products of the chemical equation CO2 + 2H2O?

Back

The products are carbon dioxide (CO2) and water (H2O).

Front

Define 'reactants' in the context of a chemical reaction.

Back

Reactants are the starting substances that undergo a chemical change.

Front

What is the difference between reactants and products in a chemical reaction?

Back

Reactants are the substances that start a chemical reaction, while products are the substances formed as a result of the reaction.

Front

What is an example of an exergonic reaction?

Back

Burning of fuels, such as Cheetos, is an example of an exergonic reaction.

Front

How does the law of conservation of mass apply to chemical equations?

Back

In a balanced chemical equation, the number of atoms of each element must be the same on both sides, reflecting that mass is conserved.

Front

What is the significance 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.
