Q

Why does things with a lower boiling point get to the top of the fractionating column?

A

Because they get to the top faster and don’t cool down

Q

Why shouldn’t you use a Bunsen burner to ehat crude oil?

A

The short chain hydrocarbons are flammable that’s why there used for fuel

16
Q

What comes first bitumen or lubricating oil?

A

Bitumen

17
Q

What’s kerosene used for?

A

Fuel for jet aircraft

18
Q

What comes out the top of a fractionating column?

A

Refinery gasses

19
Q

Wheres the hottest part of a fractionating column?

A

The bottom

20
Q

What is gasoline used for?

A

Fuels for cars!

21
Q

Big fat lions don’t kill giant rabbits is the distillation Oder is this right?

A

Yes

22
Q

What is the spine of a hydrocarbon?

A

The chain of carbon atoms

23
Q

What is it called when carbon atoms join together?

A

A single carbon bond

24
Q

What happens to a single Carbon-carbon bonds?

A

It is saturated and becomes an alkane

25
Q

How many bonds can hydrogen make?

A

One

26
Q

How many bonds can Carbon make?

A

Four

27
Q

What is a good property of shorter chain hydrocarbons?

A

They release energy quickly by burning so there is a great demand for them as fuels

28
Q

What is the formula for fuel with LOTS of oxygen?

A

HC+O2=C+H2O

29
Q

What is the formula for fuel with little oxygen

A

CH4+CO=CO+CO2+H2O+H

30
Q

What dose burning fossil files produce?

A

Sulfur oxide and nitrogen oxide (when burned at high temperatures) this a cause of acid rain
