Determine the acid dissociation contant for a 0.10M acetic acid solution that has a pH of 2.87. Acetic acid is weak monoprotic acid.
General Chemistry: Energy, Volume, Mass, Molarity, and Moles, Benzene is an organic solvent with the formula C6H6. It boils at 80.1 degrees celcius and melts at 5.5 degrees Celsius. Benzene's density is 0.88gm/ml; its heat of vaporization is 30.0 ..
Many metals pack in cubic unit cells. The density of a metal and length of the unit cell can be used to determine the type for packing. For example, gold has a density of 19.32 g/cm3 and a unit cell side length a of 4.08 Å. (1 Å = 1. 10-8 cm.)
Compound A has the molecular formula C14H25Br and was obtained by reaction of sodium acetylide with 1,12-dibromododecane. On treatment of compound A with sodium amide, it was converted to compound B (C14H24).
