4) If you were to distill acetone in a lab located in the Colorado Rocky Mountains where the atmospheric pressure is approx. 570 torr (mm Hg), would it have a higher or lower bp than it would here in the Bronx? Concisely explain.
Homework Answers
More the elevation of hight , lower is the atmospheric pressure, lower is the boiling point. Hence low temperature is require to boil at higher altitudes.

1. (a) A student is diluting a stock solution of a Vitamin C solution. The concentration of the stock solution is 3.687x10 M. 4.00 mL of the stock solution was transferred into a 50 ml volumetric flask and diluted to the mark with water. What is the final concentration of the dilute Vitamin C solution? (Refer to page 70 in the lab manual). (b) Would a solution prepared the same way but with 2.00 ml...

Exposure to arsenic in drinking water is associated with increased prevalence of diabetes. We previously reported an association of diabetes and urinary concentration of dimethylarsinite (DMAS"), a toxic product of arsenic methylation by arsenic (+ 3 oxidation state) methyltransferase (AS3MT). Here we examine associations between AS3MT polymorphism, arsenic metabolism and diabetes. Fasting blood glucose, oral glucose tolerance and self-reported diagnoses were used to identify diabetic individuals. Inorganic...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
