What did you notice about the way the soil particles sank in the water? Which type of soil is on the bottom? Why?
The amount of each size particle in soil is the particle size distribution. Do you think this is a good way to determine particle size distribution? Why or why not?
Explain why the results in this experiment may look different when done in different locations.

Mrs. smith ordered a root beer float (vanilla ice cream + root beer). mrs. smith noticed that the three states of matter (solid, liquid, and gas) all existed simultaneously in her root beer float. a. identify each phase of matter in the root beer float. b. describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? ) c. identify one phase change you would see in a root beer float and described what causes this change.

What does the mass of 0.7891 mol of ferric oxide (fe2o3)
