fractional distillation Flashcards
1
Q
what is crude oil
A
- an oil made from thousands of years worth of decomposition of dead matter
- consists of hydrocarbons
2
Q
hydrcarbon
A
compound that contains only hydrogen and carbon
3
Q
explain the process of fractional distillation in the context of crude oil
A
- separating a mixture using the varied boiling points of a substance
- crude oil is heated at 350 degrees and goes up the fractioning column, the substances condense depending on the length of chains within individual substances
4
Q
how does chain length change down the fractioning column
A
chain length increases
5
Q
how does flammability change down the fractioning column
A
flammability decreases
6
Q
how does boiling point change down the fractioning column
A
boiling point increases
7
Q
4 types of hydrocarbons you need to know
A
methane
ethane
propane
butane
