Law of Conservation of Mass Study Flashcardziz

Front

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that in a closed system, mass is neither created nor destroyed during a chemical reaction. The total mass of reactants equals the total mass of products.

If 12g of Carbon reacts with 16g of Oxygen, how much carbon monoxide (CO) is formed?

Back

28 g

Front

What does it mean for a chemical equation to be balanced?

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.

Front

In the reaction CH₄ + 2O₂ → CO₂ + 2H₂O, is the equation balanced or unbalanced?

Back

Front

What happens to matter during a chemical reaction according to the Law of Conservation of Mass?

Back

Matter can be transformed or changed, but it cannot be created or destroyed.

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that undergoes change during a chemical reaction.

Front

What is a product in a chemical reaction?

Back

A product is a substance that is formed as a result of a chemical reaction.

Front

What is the total mass of reactants in the reaction 2H₂ + O₂ → 2H₂O?

Back

The total mass of reactants is equal to the total mass of products, which is the mass of water produced.
