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 closed system; it can only change forms.

Front

How can you demonstrate that matter is conserved in a chemical reaction?

Back

By measuring the mass of reactants before the reaction and the mass of products after the reaction, you will find that the total mass remains the same.

What is a mixture, and how does it relate to the conservation of matter?

Back

A mixture is a combination of two or more substances where each retains its own properties. The total mass of a mixture is conserved, as it equals the sum of the individual masses.

What is the difference between a physical change and a chemical change in terms of matter conservation?

Back

In a physical change, the form of matter changes but its mass remains the same. In a chemical change, matter is rearranged, but the total mass before and after the change remains constant.

Front

What role does mass play in understanding the conservation of matter?

Back

Mass is a measure of the amount of matter in an object. In the context of conservation of matter, the total mass before and after a process must be equal.

Front

How can you experimentally verify the conservation of matter in a closed system?

Back

By conducting a reaction in a sealed container and measuring the mass before and after the reaction, you can verify that the mass remains constant.

Front

What is an example of a physical change that demonstrates conservation of matter?

Back

Dissolving sugar in water is a physical change where the total mass of the sugar and water remains the same, demonstrating conservation of matter.

Front

What is an example of a chemical change that demonstrates conservation of matter?

Back

Burning wood is a chemical change where the mass of the wood and oxygen used equals the mass of the ash, gases, and other products formed.

Front

Why is it important to understand the conservation of matter in scientific experiments?

Back

Understanding conservation of matter helps scientists predict outcomes, balance chemical equations, and ensure accurate measurements in experiments.

Front

What is a closed system in the context of matter conservation?

Back

A closed system is one where no matter enters or leaves, allowing for accurate measurement of mass before and after a reaction.
