Why do oil and water not mix?1. Describe the physical properties of oil and water. Discuss why they do not mix.
2. Describe the chemical composition of crude oil and how your simulation mimics an oil spill.
3. Describe at least 4 methods that could be used to attempt to separate the oil and water at home. Based on the four methods postulate which method would work better than the others.
Benzene is a organic solvent with the formula, The volume occupied by 1 micromole of liquid benzene and the volume occupied by 1 megamole of benzene as a vapor at STP (assume an ideal gas)
