Fractional Distillation Of Crude Oil Flashcards
1
Q
What is crude oil
A
Crude oil is formed from the buried remains of plants and animals -it’s a fossil fuel? It’s also a mixture of hydrocarbons
2
Q
What is a mixture

Q
Why aren’t hydrocarbon molecules in crude oil chemically bonded to one another
A
