Answer:
here are the answers !
Explanation:
1) the land surface cools quicker than the water surface at night. So the best Answer would be D
2) I think this answer would be True because When a fluid such as air or water touches a hot object, it can heat up and then move in bulk as a fluid, thereby carrying the heat quickly to new locations. Hot air rising is a common example of heat convection.
3) Wind is the movement of air from areas of high pressure to areas of low pressure.
S²⁻ cannot be reduced further.
<u>Explanation:</u>
S²⁻ cannot be reduced further
In the periodic table, Sulphur has the atomic number of 16.
So, the arrangement of electrons in the orbits would be 2, 8, 6
The outermost orbit has 6 electrons.
It can gain two more electrons to complete its outermost orbit and the valency of the sulphur then becomes 2-
Therefore, in S²⁻ the valence electrons are complete in the outermost orbit and cannot gain more electrons. Therefore, it cannot get reduced further.
