2)Explain a situation(list liquid examples and order) in which two liquids of different densities form two layers.
-If you have water and oil in one cup they will form two different layers because they are different densities. Oil is less dense than water so it will be on top of the water.

3)Explain a situation in which two liquids of different densities form one layers.
-Some liquids will be chemically attracted to each other and will therefore be able to mix even though they have two different densities. An example of this would be water and ethanol.

4)List the density of osmium, lead, and aluminum
-Osmium=22.61 g/cm
-Lead=11.34 g/cm
-Aluminum=2.70 g/cm
