Answer:
The answer is D.
Explanation:
Methane (CH4) is a non-polar hydrocarbon molecule made of a single carbon atom and four hydrogen atoms. It is found in nature in the form of natural gas. It is non-polar because the difference in electronegativities between carbon and hydrogen is not sufficient to produce a polarized chemical connection between these two elements.
The methane molecule has a tetrahedral structure in terms of molecular geometry. Because the molecule is not planar, the angles between the H-C-H bonds are 109.5°, which is more than the 90° that they would be if the molecule were planar.
I believe the answer would be A, "They both described the oceanic type" because it is on the ocean floor, meaning it would be oceanic, so at least student B is talking about oceanic, and I'm pretty sure what student A means is that it's 5-12 KM below sea level, so that would also fit he oceanic type. Hope it's correct! :)
