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).
4.176 g of Al that was reacted with excess HCl if 2.12 L of hydrogen gas were collected at STP in the following reaction.
2 Al (s) + 6 HCl (aq) → 2 AlCl₃ (aq) + 3 H₂ (g)
<h3>What is an ideal gas equation?</h3>
The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).
2 Al (s) + 6 HCl (aq) → 2 AlCl₃ (aq) + 3 H₂ (g)
Given data:
Volume of 
(g) = 5.20L
At STP
Pressure= 1 atm
Temperature =273K
R = 0.0821 L.atm/mol K
PV=nRT
n= 
n= 
n= 0.2324 mol
2 Al (s) + 6 HCl (aq) → 2 AlCl₃ (aq) + 3 H₂ (g)
=
=4.176 g of Al
Hence, 4.176 g of Al that were reacted with excess HCl if 2.12 L of hydrogen gas were collected at STP in the following reaction.

Explanation:
Mass number is the sum of protons and neutrons inside an atom.
Atomic mass = no. of protons + no. of neutrons
Energy=mass x the speed of light squared.
