Question

surface of the lake is at 2degree celcius.the temperature at the bottom of the lake is?

Answer 1

Explanation:

Covalent Bond: The atomic number of carbon is 6. Its electronic configuration is 2, 4. It requires, 4 electrons to achieve the inert gas electronic configuration. But carbon cannot form an ionic bond

It could gain four electrons forming C4- cation. But it would be difficult for the nucleus with six protons to hold on to ten electrons.

It could lose four electrons forming C4+ cations. But it requires a large amount of energy to remove four electrons.

Thus, carbon overcomes this problem by sharing of its valence electrons with other carbon atoms or with atoms of other elements.

Answer 2

Answer:

For deep lakes with no heat sources and no movement, the temperature at the bottom will be 3.98 C, because water at that temperature is at its most dense.
