Chemistry Homework Help Crude Oil

Homework help crude oil?

a) how is crude oil formed?
Organic material from life falls to the bottom the ocean and accumulates. It is deeply buried. Heat and pressure turn it to oil.

b) Where do we get it from and how do we extract it?
It is found where it gets trapped by layers of non porous rocks. We drill for it and pump it out.

c) What type of substance (element, mixture, or compound ) is it?
hydrocarbon

d) What substances make it up?
hydrocarbons made of hydrogen and carbon. Gasoline, natural gas, diesel

e) How do we get these substances from crude oil?
We distill it in refineries.

B) Formed by the decay of dead sea creatures.
C) Consist of a mixture of very large molecules.
D) Is purified in an oil rig

2 Which is a correct statement about fractional
distillation?

A) Oil is separated into fractions with the same size molecule
B) Oil is separated into fractions with the same density
C) Oil is separated into fractions with similar size molecules
D) Oil is separated into alkanes and alkenes

3 Which is a correct order for these fractions working down from the top of the column?

A) Fuel gas, kerosine, petrol, diesel, bitumen
B) Fuel gas, diesel, kerosine, petrol, bitumen

Chemistry homework help please!?

Most of the carbon chains are very long in crude oil ( a very large number), they are shortened by cracking. The longer the c chains the more viscous and thick it is as the long chain molecules cant move past one another as well.
It is made up of a number of components, napthas have C 5-7 kerocene C 7-11, petroleum and other fuels longer chain lengths. Oils have about 15-20 C atoms in their chains.
These are all components of crude oil.

Hope that helps

Crude Oil Homework Help?

May be up to the level of taking into consideration the usage, we r not completely making use of it properly, though it is main point now that there is hazardous, irrational use. the main hindering one that makes the wastage of crude oil can be enlisted as;no proper transportation(if in water ways it is oil spill which is in everybody's mouth)
Now there are many researches in their way to find a eco-friendly fuel to take up its place of the crude oil's,though many have come up with fuel with soya etc..lets hope their researches be successful and save the future Earth......................................

I desire a holiday with a scene Of green, inexperienced and inexperienced A summer season of inexperienced timber A panorama of inexperienced grass A view filled with green greens the color green Is a cosmetic that experience bought to be noticeable! From a moving vehicles monitor And at the same time we keep onto the ones machines That deprives us of the colour inexperienced take into account they furnish us vaccines As good as support the air to be convenient So for inexperienced, inexperienced and green i will journey continents throughout and in-among and in addition to any role that i have certainly not been i will make it movements easily to seem inexperienced, inexperienced and green

Distillation HOMEWORK HELP?

1)

Distillation is using heat to separate out different molecules by boiling. Different molecules have different boiling points, so at a given temperature, only one type of molecule will evaporate.
