Crude oil is a mixture of many liquids. The crude oil enters the bottom of a tall column, where the mixture is heated. The subst
ances rise up the column until they cool down and condense back to liquids. The components of crude oil can be separated because of differences in which property?
A/density
B/magnetism
C/boiling point
D/physical state
Fractional distillation is a process that is often employed to separate various liquids from a mixture of liquids based on the respective boiling points. As the liquid mixture is heated, the component with the lowest boiling point will vaporize first and can be separated out through a condenser.
Crude oil is a mixture of several volatile hydrocarbons each having a different boiling point. Therefore, the difference in boiling point can be used to separate them through the method of fractional distillation
<span>H2S has 2 bonds which means that it has two shared electron pairs. It has 2 lone pairs on electrons. It's the only one where the 2 are the same.</span>
Ionic (or electrovalent) compounds conduct electricity when there they are in the aqueous state/solution because the charges of ions of these compounds are what carry the electric charges in the aqueous solution as a result of free movement within the aqueous solution which they do not "have" when in there solid state (where they have a highly restricted movement/compacted structure).
