Answer: Option (B)
Explanation:
Geology is the study of all the earth dynamic processes, about the various types of rocks, its physical and chemical properties, about the ancient lives, and covers many more topics.
Whereas, Oceanography refers to the study of the marine ecosystem, its biological properties as well as its physical and chemical properties.
This two fields of science namely geology and oceanography is required to study about the deep sea vent structures as well as the life forms that exists around them.
Deep sea vents are the cracks and openings found underwater from which the hot water comes out in association with numerous gases.
Thus, the correct answer is option (B).
D) The movement of electrons between atoms
<span>We started with twenty ions of Mg and twenty ions of F. Producing 20 units of AgCl requires twenty MgCl2 since it is the only source of magnesium. Similarly it requires twenty AgF since it is the only source of silver.</span>
Balanced Equation: H2SO4 + 2NaOH --> 2H2O + Na2SO4
Moles= Mass/RMM
= 65.5/40
= 1.6375
Mole Ratio = 2:2
= 1.6375
Mass (H2O) = 1.64 x 18
= 29.5 g
Density(D) is defined as Mass(M) divided by Volume(V).
The formula for Density is:
D = M / V.
Another way to remember the formula for Density is to remember "Mass per unit of volume".
I hope this helps!
