1. What is an element?
2. What is a compound?
3. How can you tell the difference between an element and a compound?
4. Give an example of an element.
5. Give an example of a compound.
6. If given examples of formulas, be able to tell whether they are elements or compounds.
(example- H is an element. H2O is a compound.)
7. What is a mixture?
8. What is a physical property?
9. Give an example of a physical property.
10. How might you separate a mixture of iron filings and salt?
11. What is a physical change?
12. What is a chemical change?
13. What are some ways that we might know a chemical change has taken place? (look at the
worksheet that I gave you that tells you about physical/chemical changes)
14. If given examples of changes, be able to tell whether they are physical changes or
chemical changes. (example-breaking a glass is a physical change, burning wood is a
chemical change)

16. If I burn a 25 g piece of wood in a closed glass jar, with 10 g of oxygen, how much
carbon dioxide and water should form? (Imagine that the wood burns perfectly and the
only remaining products are carbon dioxide and water). (HINT: Use the law of
conservation of mass to figure this out)
