Answer:
B. The principal quantum number (n) is 6, the angular momentum quantum number (ell) is 2, and there are 5 electrons in the subshell.
Explanation:
Given;
electronic configuration of 6d⁵
where;
6 in the configuration shows that, the principal quantum number (n) is 6
d is the subshell
d orbital has angular momentum quantum number (l) of 2
s orbital, l = 0
p orbital, l = 1
d orbital, l = 2
f orbital, l = 3
5 in the configuration means that there are 5 electrons in the subshell
Therefore, 6d⁵ symbol means that "The principal quantum number (n) is 6, the angular momentum quantum number (ell) is 2, and there are 5 electrons in the subshell".

Does methanol keep things from freezing?</h3>
Methanol is an extremely effective anti-freeze agent. Even little amounts can have a significant effect on freezing temperatures. Deschamps, Mousis, Sanchez-Valle, and Lunine investigated the impact of methanol concentrations of a few percent and discovered that they might play a major role in the formation and preservation of a subsurface ocean.
The effects of pressure on pure ice and pure methanol have been widely researched, but the behaviour of water-methanol mixes has not been as thoroughly explored. We intend to conduct a series of experiments to investigate how various spots on the methanol-water phase diagram change under pressure

The reaction equation:
2H₂S + SO₂ → 3S + 2H₂O
Calculating moles of H₂S:
10 / 34 = 0.29
Moles of SO₂:
10 / 64 = 0.15
Stoichometric amounts of each reactant are present so the moles of S formed will be:
0.15 x 3 = 0.45
Mass of S formed = 14.4 grams
