Draw the major E2 reaction product formed when trans-1-chloro-2-ethylcyclohexane reacts with hydroxide ion in DMSO.
At 20 degree C, the vapor pressure of C2H5OH (ethyl alcohol) is 43.9 torr. The vapor pressure of water at this temperature is 17.5 torr. These liquids behaved ideally. What would be the vapor pressure of a solution prepared by mixing 100 g of ethy..
the element europium exists in nature as two isotopes eu-151 has a mass of 150.9209 amu and eu-153 has a mass of
Which pair is written with the first member having the higher boiling point?
consider a lithium atom two of its electrons are in the 1sshell and the third is in the 2s shell1- consider the lithium
A calorimeter that contains 2500 g of surrounding water is used to measure the heat associated with the reaction of 520 g of a reactant. Calculate the energy, in joules per kilogram of reactant, associated with the reaction
Suppose a mercury thermometer contains 3.450 of mercury and has a capillary that is 0.180 in diameter. How far does the mercury rise in the capillary when the temperature changes from 0.0C to 25.0 C? The density of mercury at these temperatures is..
