Read each question carefully and answer to the best of your ability. Remember the Law of Conservation of Mass: matter cannot be created or destroyed, only transformed.
1. What does the Law of Conservation of Mass state?
Mass can be created and destroyed.
Mass is always gained in a chemical reaction.
Mass cannot be created or destroyed.
Mass is always lost in a chemical reaction.
2. If you burn a piece of wood, what happens to its mass?
It is destroyed.
It is converted into energy and disappears.
Its mass is conserved, but it changes form (ash, smoke, gas).
It increases because fire adds mass.
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. When ice melts into water, its mass .
5. The Law of Conservation of Mass only applies to solids.
True
False
6. If a log burns and turns into ash and smoke, the total mass of the ash and smoke combined will be less than the original log.
True
False
7. Describe an everyday example of the conservation of mass.
8. Observe the image below of a balance scale. If the total mass on the left side is 50 grams, and the total mass on the right side is 50 grams, what does this demonstrate about the conservation of mass?
