The boiling points of hex-1-ene (64 ∘c) and hex-1-yne (71 ∘c) are sufficiently close that it is difficult to achieve a clean separation by distillation. show how you might use the acidity of hex-1-yne to remove the last trace of it from a sample of hex-1-ene.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

bcde is the incorrect answer it is a

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
