Answer:
Crude oil is separated by fractional distillation. Crude oil is heated to vaporize the different hydrocarbons in a tank which is cool at the top and hot at the bottom. The vapours then rise and the different hydrocarbons condense at their specific boiling points, allowing them to be separated.
Lighter products, such as butane and other liquid petroleum gases (LPG), gasoline blending components, and naphtha, are recovered at the lowest temperatures. Mid-range products include jet fuel, kerosene, and distillates (such as home heating oil and diesel fuel).
Answer:
The conjugated base of ammonium ion 
is 
Explanation:
A conjugate base is obtained by addition of proton 
. In order to get the conjugate base of , we need to add a proton to ammonium ion. We will get after addition of proton to ammonium ion.
Hence, the conjugate base of is
