1. A student measured the boiling point of a liquid and found that it had two different boiling points. What is the best conclusion the student could draw?
 * Answer the following questions:**

2. How could you separate a mixture of three liquids according to their densities?

3. In a solution, what is the solute and what is the solvent?

4. Describe three ways to dissolve solids faster and explain why each works.

5. A student was given liquid and told that it contained a mixture. How could the student determine whether or not the mixture was a solution, a suspension, or a colloid?

6. Aluminum oxide is a solid that is insoluble in both water and alcohol. Ammonium ferrous sulphate is a solid that is soluble in water but insoluble in alcohol. How could you separate a mixture of aluminum oxide and ammonium ferrous sulphate?

7. Suppose you were given an unknown liquid and asked to determine if it was an element, a compound, or a mixture. What would you do? How would this help you find out what it was?

8. What are some examples of how to break down a compound? (see Figure 7, pg. 531)

9. How is a compound different from an element?

10. How is a mixture different from a compound? (there are several answers to this)
