What is a hydrocarbon?
How is the polarity of hydrburbur, its solubility, its density and
its viscosity?
What are the physical and chemical properties of hydrocarbons and water?
How are the molecular structures of hydrocarbons in petroleum
and water?
What method or technique can be used for the separation of
hydrocarbons from water?
What are the intermolecular interactions between the chemicals involved (hydrocarbons and water)?
Homework Answers
1. A hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.
2. Polarity:Hydrocarbons are molecules that have little or no polarity because they do not contain electronegative atoms.
Solubility:Hydrocarbons are non polar and so should be soluble in non polar solvent and insoluble in polar solvent.
Density:Liquid hydrocarbons are less dense than water. The density of methane is less dense than air but propane and butane is denser than air.

3) The polarity of a molecule is a consequence of its structure and is one of the determinants of the physical and chemical characteristics exhibited by the molecule. If you have ever observed a bottle of oil and vinegar salad dressing before shaking it you have observed one of the consequences of the polarity of molecules, "like dissolves like” and consequently "oil and water don't mix”. (It is important to point out here that vinegar is 95% water...

In the lab, a student determines the density of a metal object by measuring its mass on a balance and its volume by displacement in a graduated cylinder. The data collected by the student is shown. mass of object: 42.231 g volume of water in cylinder before object submersed: 28.01 mL volume of water + object in cylinder: 34.39 mL Calculate the density of the object. d = g/mL Based on the recorded volume data, and assuming that the student...

6. Partition coefficients describe how a solute is distributed between two immiscible solvents. They are used in drug design as a measure of a solute's hydrophobicity and a proxy for its membrane permeability. If morphine has a partition coeffiecent, K, of 2 in petroleum ether and water, and a water solubility of 1.0 g/17.6 mL, what is the solubility of morphine in petroleum ether?

Based on solubility, density, and polarity information what will happen if a caffeine extraction and sublimation experiment is carried out at 100°C? (Note: show the outline, the experiment might not work perfectly in the actual lab, but a hypothetical outline is needed). Procedure below: Boil 20mL DI water. Place 1st tea bag in beaker taken off heat and cool to handling temperature. Squeeze tea from bag without breaking it. Boil the mixture. Repeat steps with 2nd teabag. Cool to room...
