Robert Hetue's List: 109H Honors Project

For some reason the Oct 16th link leads to "website has expired". In order to access these newly added pages, one can select the Oct 19th tab and then click backwards on the navigation bar to access this page and the others placed in the Oct 16th section.

I really like this setup for the "day" pages that present an outline of the reading for the day rather than redirecting to the Moodle course first. However, Oct. 21 and onwards aren't structured like Oct. 16 and Oct. 19. Can the administrators set up later "day" pages like this one?

The Homework (and Review Homework) assignments are due Sunday rather than Friday. I think this will go for all following weeks as well.

It scared me a little when I saw this page say that Homework was due today.

The insertion of the image depicting the pressure increase is kind of awkward, as it's jammed in the middle of a sentence. Perhaps it could be repositioned after the second paragraph, after "equilibrium shifts".

The text to the right of the anode/cathode picture is difficult to read. Is there a template of sorts that automatically inserts a break after a picture? {{-}}, perhaps? Or whatever method can be used to relocate "the negatively charged..." under the picture.

Could it be noted here that the polarity within a molecule is caused by electronegativity? It would be useful to show the scale that predicts what type of bond is created based on the difference in electronegativity, which means physically that electron density is higher on a certain side of the molecule making that side negative. Illustrating what actually happens would be more helpful than the +/- ball picture, I think.

The paragraph above the Ka table should be changed to match the table itself. The table is arranged alphabetically, so the sentence saying "arranged in order of their strength" should be changed accordingly.

Bit of Wiki error in the paragraph below the Solution for Example 1, with linking to electrolytes and a table. Not sure if it's something with the piped linking, or if a <nowiki> tag is present. Also, in the description of weak oxyacids, the subscripts m and n should be switched in HnXOm; hydrogen atoms are always equal to or less than the number of oxygen atoms, not the other way around.

Just a small error on part d) of the last example. Ethane does indeed have a larger electron cloud than fluorine; the last sentence should omit the F2 and say ethane has the higher boiling point.

Just noting that the hydrocarbon molecule examples in the petroleum overview do not yet have jmol images. That's probably because most of them are complicated molecules and don't have jmol molecules uploaded, though I think I'll go on ChemPrime and see if there's an available jmol image for propane. Also, it might be useful to note that hydrocarbons with multiple bonds are called unsaturated because they have the potential to break the multiple bonds and form more single ones.

Within the section on conformations, it could be noted that in addition to the staggered and eclipsed conformations, the positions of each molecular group bonded to each carbon in relation to the molecular groups bonded to the other carbon affect stability.

In the paragraph before the 3-methylhexane jmol image: "In order to find chiral carbons in a simple alkane, find any carbon which has four different THINGS attached to it...." I remember my TA was a bit picky about how we referred to bonded groups.... might want to call them molecular groups just to give the right impression, you know :)

In the first paragraph, when noting the alternating single and double bonds in the benzene structure, the term "conjugated" could be used. I remember a Challenge Problem concerning Crystal Violet that took about five hours to do and would have been quite a bit easier if I was familar with that term.

Several typos on this page: above the graph showing the variation of phenolphtalein color, the sentence should read "Thus, at the point where the indicator is half conjugate acid and half conjugate base,"
and in the thumbnail caption of the image, "Note that the color change is confined to a fairly narrow pH range." Also, in the Properties of Selected Indicators table, the first indicator shows up only as "blue"; it's probably "methyl blue" or a longer-named indicator. The second column with a single pH listed should also be titled "indicator equilibrium" or something similar.

Small typo underneath the ice bomb video; the temperature should be negative 77 degrees C, not positive.

Some odd problems with the jmol images here. The image for 1-propanol reads propan-1-ol, similarly with 1-butanol, 2-butanol, and 2-methyl-2-propanol. Also, the > before the C=O group in the paragraph discussing the oxidation of secondary alcohols to produce ketones should be removed.

The advanced jmol model here is really helpful! Having this sort of interactive molecule would be useful on the other organic pages as well.

It should be made more clear that amines react with carboxylic acids to form an amide bond, a functional group in itself and the key to an amino acid, rather than just mentioning that the an amino acid contains anime and carboxyl functional groups.

In the Moodle Homeworks, the terms "molecular" and "covalent network" are often used in a matching exercise to different molecules. I have also seen "molecular network" and "covalent", and I assumed whichever term had the "network" part in it was to be matched to the macromolecule. If there is any difference between a "molecular" (perhaps the term was emant to be intramolecular?) and "covalent" bond, they could be highlighted here.

The content of this exemplar is exactly the same as the next page in the series, "Constituents of the Earth's Crust". There probably isn't a reason for identical information to be present in two pages within the same chapter. The info here is about many different macromolecules in the earth's crust, not just silicon dioxide, so the exemplar should be considered a duplicate page and possibly deleted.
