Flashcard on Law of Conservation of Mass

Front

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction; it remains constant.

Front

What are physical changes?

Back

Physical changes are changes in form, not in substance, meaning the material's identity remains the same.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.

Front

What are reactants?

Back

Reactants are the starting substances in a chemical reaction, found on the left side of the equation.

Front

What are products?

Back

Products are the substances formed as a result of a chemical reaction, found on the right side of the equation.

Front

What is an element?

Back

An element is a pure substance that cannot be broken down into simpler substances and is made of only one type of atom.

Front

What is a compound?

Back

A compound is a substance formed when two or more elements are chemically bonded together.

Front

What is a mixture?

Back

A mixture is a combination of two or more substances that are not chemically bonded and can be separated by physical means.

Front

How do you determine the mass of products in a reaction?

Back

The mass of the products in a chemical reaction is equal to the mass of the reactants, according to the Law of Conservation of Mass.

Front

What is the significance 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, reflecting the Law of Conservation of Mass.
