Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. What does the Law of Conservation of Matter state?
Matter can be created and destroyed.
Matter can only be destroyed, not created.
Matter cannot be created or destroyed, only rearranged.
Matter is always lost during chemical reactions.
2. If you burn a log, what happens to its mass?
The mass is destroyed.
The mass is converted into energy.
The mass is rearranged into ash, smoke, and gases.
The mass increases.
3. In a closed system, the total mass of the reactants before a chemical reaction is equal to the total mass of the after the reaction.
4. The Law of Conservation of Matter applies to both physical changes and changes.
5. When ice melts into water, its mass decreases.
True
False
6. If a gas is produced during a chemical reaction, its mass can escape the system and be lost.
True
False
7. Describe a real-world example of the Law of Conservation of Matter in action.
8. Observe the diagram below showing states of matter transitions. Explain how this diagram illustrates the Law of Conservation of Matter.
