if ethyl chloride (density=0.92 g/mL) were used to extractethylene bromohydrin (density +2.41 g/mL) from an aqueous solution: a.) Can you be certain that the organic layer would from the upper layer? Eplain in details. b.) How could you test to determine which is the non aqueous layer? Explain in details.
Compute the hydroxide ion concentration in a NH 3 solution that is 0.091 M and 0.028 M NH 4 Cl. Kb of NH 3 is 1.8 x 10 -5 .
Calculate the specific heat capacity of a sample liquid if this 100 g sample of an unknown liquid absorbs 2000 J of heat energy, raising the liquid's temperature from 50 degree Celsius to 70 degree Celsius?
The product formed is 2-hexanol, is this an example of 1,4 addition, or proceeds via a carbanion, or is an example of electrophillic addition, or results in sp2 hybridized carbon being transformed into a sp hybridized carbon?
what volume of 420 ml of hydrogen occupy if the temperature is raised from 0 C to 95 C?
why we call benzene phenyl and not benzyle when one hydrogen is removed because in case of alkanes we name them alkyl on the removal of one hydrogen atom.
Considering the mixture of the two compounds and range of the melting points, the reason recrystallization was difficult was due to a broad melting point range.
