what is crude oil a mix of? [1 point]
hydrocarbons
define hydrocarbon [2 points]
a compound [1] made of Carbon and Hydrogen atoms only [2]
In a lab-sontrolled fractional distillation, why is the ethano-water mix heated directly?
as ethanol is flammable
give 3 components of a lab-controlled distillation apparatus set up
3 ftf: themometer condenser fractionaing column round-bottomed flask
what temperature is oil heate to in a fractionating column
370*C
what happens to the vapourised oil as it rises, and why? [2 points]
cools and condenses [1] because the fractionating column is very hot at the bottom but much cooler at the top [2]
where to heavy fractions condense? why? [3 points]
condense near the bottom [1] because they have a high boiling point [2] and large molecules [3]
where to lighter fractions condense? why? [3 points]
condense near the top [1] because they have a low boiling point [2] and small molecules [3]
