Write a chemical equation for the reaction that occurs between stearic acid and triethanolamine under the conditions of the experiment. How does the product of this reaction promote the formation of the lotion, which part is reacting? which part is polar and non polar.
For a certain chemical reaction, DH is
How could you bring about the subsequent conversions. You must give the needed reagents and conditions and write and equation.
The Kow for carbon tetrachloride is 220. Using the rule of thumb that log(Koc) = .8*log(Kow), and assuming an organic carbon content of 1% you can estimate the retardation factor for carbon tetrachloride.
Problem- Transition metals show great similarities within a given period as well as within a vertical group. Why
calculate the activation energy for diffusion for a system where the diffusion coefficient doubles its value from 700k to 1200k. R=8.314J/molk.
Consider the Lewis Resonance structure for the chlorite ion. How many total structures can be drawn, and how many of those structures obey the octet rule?
A lab protocol on synthesizing sulfathiazole from p-acetamidobenzenesulfonyl chloride and 2-aminothiazole. It would be appreciated if exact amounts of reagents, solvents, etc (in grams, mmols, mls - etc), could be given.
Use the Nernst equation to calculate the Cd2+ concentration when given cell potential of +0.768V and Mn2+ concentration of .500M
Draw the expected compound: that should be clear from the lab handout, the pre-lab lecture, and what natural source you used. Figure out how manyunique Hs there are. Look for symmetry.
you have 2.50 ml of 4.00 M sugar solution. You add 217.3 ml of water to this solution. determine the concentration of the sugar solution after the water has been added.
Problem- For the titration of 50.0mL of a 0.100 M solution of a dibasic compound with 0.0500 M HCl calculate the pH at 100mL (1st equivalence point) and at 145 mL
One of the putative base pairs is more prone to propeller twist than the other. Which base pair is it and why?
