Answer:
C
Explanation:
A - Crude oil is composed for hundreds of hydrocarbon, not less than ten.
B - Is formed in specific conditions of temperature and pressure
C - It's fractionated to form gasoline, lubricants, CH4, plastics and many other products made of hydrocarbon.
D - We have crude oil located more than 4000 yards below the surface in countries like Brazil
E - The crude oil is very thick and don't have an specific usage, so we need to refine it.

Answer:
Temperature decreases and density increases
Explanation:
Let us remember that density of a material increases as the temperature of the material decreases. So the cooler a material becomes, the denser it becomes also.
Between points B and C, the material rapidly cools down and the temperature decreases accordingly. This ultimately results in an increase in density since cooler materials are denser than hot materials.
<span>the atomic mass of nitrogen is 14. There is 1 nitrogen atom in the molecule so the percentage of N is :
14/35 x100% = 40%</span>
The correct option is C. The amount of MgCl2. we know this because <span>no matter how much you increase KOH, if you dont increase Mgcl2, the amount of Mg(OH)2 remains the same. Hope this works for you</span>
