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.
if 525 mL of gas at 25 degrees celcius is heated to 50 degrees celcius at constant pressure, calculate the new volume.
Exact potential difference in the concentration cell, What will be the exact potential difference in the following concentration cells?
Hydrogen was cooled from 150 c to 50 c. It's new volume is 75 ml. What was the original volume?
Calculate the mass of ethylene glycol (C2H6O2) that must be added to 1.00 kg of ethanol (C2H5OH) to reduce its vapor pressure by 10.0 torr at 35 °C. The vapor pressure of pure ethanol at 35 °C is 1.00 × 10^2 torr.
Just transfer this solution completely to a flask of 1L volumetric and dilute to exactly 1 liter and then compute the Fe 2+ ion concentration.
Calculate percent recovery of panacetin from the individual masses of its mictures, sucrose (.044g), aspirine (.093), and the unknown (.339).
The density of water decreases from 1.000g/mL at 3.98°C to 0.9170g/mL as ice at 0°C. By what volume (in mL) would a 2.632 liter flexible plastic bottle increase.
The reaction of calcium hydride with water can be used to prepare small quantities of hydrogen gas, as is done to fill weather observation balloons.
