It is usually desirable to minimize the number of transfer steps while conducting an extraction. For extracting an organic compound from an aqueous solution to an organic solvent, what solvent(s) diethyl ether, dichloromethane, ethanol or hexane would require fewer transfers

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
