Compounds that are gases at room temperature are covalent bonds (nonmetal + nonmetal).
Answer:
Via covalent bonds
Explanation:
Atoms in molecules are bonded together via covalent bonds. Covalent bonds are bonds that are formed by sharing of the valence electrons between two atoms.
The atoms can be of the same kind or of different kinds.
- In most molecules, the two atoms are connected by sharing of their valence electrons.
- This way, each atom can attain stability by becoming isoelectric with the nearest noble gas.
- Some molecules are monoatomic, some are polyatomic.
Answer:the first one is D second one is A and the third one is A :D
Explanation:
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.
