How are hydrocarbons arranged in crude oil?
In chains or rings
What is fuel used for?

What is bitumen used for?
Roads
Why are some HydroCarbons flammable?
They are short-chained and have weaker molecular forces.
-Short chained HydroCarbons are normally a gas at room temperature.
Why are long-chained HydroCarbons harder to break? (Bonds)
They have a big number of bonds between atoms that don’t all break at the same time. Takes longer to break all bonds.
Meaning of viscosity?
How well something flows.
How is sulfur dioxide created?
Sulfur impurities in crude oil burn and reacts with oxygen.
How does sulfur dioxide turn into acid rain?
Reacts with clouds and becomes diluted.
Why is carbon monoxide bad?
- Stops blood from binding with oxygen
- Soot covers buildings in black
How is nitrogen oxide created?
