Why is smoke produced when propene is burned? Why are grasses important to humans? Why are parts of aquaporin nonpolar? Why are volatile organic compounds considered an environmental hazard? Why is crude oil called a fossil fuel? Why are fats insoluble in water?
A molecule is considered polar if it has an overall dipole moment. The dipole moment of the compound depends if the compound has polar bonds and if the geometry of the compound will permit a net dipole moment. Bond dipole moments occur due to differences in electronegativity....
Explain why beeswax is insoluble in H2O, slightly soluble in ethanol (CH3CH2OH), and soluble in chloroform (CHCl3). Why are hydrogen ions never found in an aqueous solution? Explain how you would prepare a 0.150 M solution of glucose in water. ...
Each acid produces a corresponding alkyl-phenol. The RULER test can determine the quantity present of these alkyl-phenols. These negatively affect the air release, resistivity and will transition into an insoluble state eventually. Hence monitoring of these phenol degradation products can help determine...
If you had to make a recombinant protein in your undergraduate biology class, then you know that the cost of doing this is essentially the cost of highly refined sugar water (= culture media) plus the cost of highly refined salt water (= chromatography buffers). Using sophisticated 1970s ...
other to form ferrous tannate and ferrous gallate. After oxidation, they become insoluble high valent iron, namely iron tannate and iron gallate. The former enhances water resistance, and the latter enhances blackening, so that ink is resistant to water and blackening, and the color is durable...
It is suspected that a water-insoluble solid unknown is an amine. Which of the following would be useful in confirming the suspicion? (a) 6 M HCl solution (b) 3 M NaOH solution (c) Red litmus paper In part 4 of this experiment, you are asked to pr...
Why is chloroacetic acid stronger than acetic acid? Why are the free fatty acids more easily converted into esters with a acid catalyzed method but not with the base catalyzed method? Why do while benzene fluoresces, pyridine does not? Why are fats insoluble in water? Why are volatile organi...
