Explanation:
A.
P = Ds * g * h
Height, h = 5053 ft
In m,
1541.165 m
g = 9.81 m/s^2
SG = density of substance, Ds/density of water
1.03 = Ds/1000
= 1030 kg/m^3
P = 1030 * 9.81 * 1541.165
= 1.56 x 10^7 N/m^2
1 Psi = 6894.76 Pa = 6894
76 N/m^2
= 2258.6 psig.
B.
Pressure = 4400 psig
Since,
1 Psi = 6894.76 Pa = 6894
76 N/m^2
= 3.03 x 10^7 Pa
Density = 3.03 x 10^7/(1541.165 * 9 81)
= 2006.6 kg/m^3
SG = density of substance, Ds/density of water
= 2006.6/1000
= 2.01.
C.
Density of barite = 4.370 * 1000
= 4370 kg/m^3
Total mass of slurry = mass of barite + mass of seawater
= 1030 + 4370
= 5400 kg in 1 m3 of slurry.
Mass fraction = mass of barite/total mass of slurry
= 4370/5400
= 0.81.
D.
The mud weight is a key factor. Too low mud weight may result in collapse problems, hence spill of the well will not be contained. This is because of the pressure of escaping oil against a column of fluid (the mud) having a density significantly higher than those of seawater and oil.

You never listed the options
Explanation:
A chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.
The area is 23x20 which = 460 sq ft.
If each sq foot gets 1250 flakes per min, it gets 75,000 in an hour.
The whole lawn gets 34,500,000 flakes in one hour, which would weigh 75,900,000 mg.
This equals 75.9 kg
Answer:
c2h6
Explanation:
this is because c2h6 is a ethane having two carbon being bounded to 3 hydrogen each. making it to have two molecules . for they are on group alkenes which contains two molecule.
Scientist believe that about 25 of the known elements are essential to life. Just four of these - Carbon (C), Oxygen (O), Hydrogen (H), and Nitrogen (N), - make up about 96% of the human body.
These four elements are found in the basic structure of all biochemical molecules. For example, Glucose is a carbohydrate and it's molecular formula is C6H12O6 - each molecule of glucose is made up of 6 Carbon atoms, 12 Hydrogen atoms and 6 oxygen atoms.
The other elements found can be divided into two main groups - major elements and trace elements.
The human body functions as a result of a large number of the chemical reactions involving compounds of a of these elements.
