Describe two physical properties that could be used to distinguish between pentane and octane 2 marks. 10 pH 10 1. Created at 10132016 546 PM by Cheryl Fiedler.
The osmotic pressure of an aqueous solution of a certain protein was measured in order to determine its molar mass. The solution contained 350mg of protein dissolved in sufficient water to form 5ml solution. The osmotic pressure of the solution at 25C was found to be 154 torr.

A six-membered ring intramolecular hydrogen bond in the latter compound is in part responsible for its low field shift and will be shown by clicking on the hydroxyl proton. We can take advantage of. A sample of the metallic element sodium is studied in the laboratory and a series of observations is recorded.
The samples mass is 1455 g and its volume is 150 cubic centimeters. It melts at 98. Propan-1-ol is the parent member of the class of propan-1-ols that is propane in which a hydrogen of one of the methyl groups is replaced by a hydroxy group.
It has a role as a protic solvent and a metabolite. It is a short-chain primary fatty alcohol and a member of propan-1-ols. Allyl alcohol is apparently oxidized readily since within few min after iv injection of rats with the dosage of 30 mgkg vena cava blood contained average concentration of about 24 ugmL.
Within 15 min concentration was about 4 ugmL and within 1 hr the alcohol had almost disappeared from the blood.
