See explanation and image attached
Explanation:
"A formal charge (FC) is the charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity" (chemlibretext).
We can obtain the formal charge from the formula;
Formal Charge = [number of valence electrons on atom] – [non-bonded electrons + 1/2number of bonds].
A structure in which SO2 has a zero formal charge is attached to this answer.

Answer:
root mean square velocity of nitrogen at 25°c is 515 m/s
correct option is b) 515 m/s
Explanation:
given data
temperature = 25°c = 25 + 273 = 298 K
to find out
root mean square velocity of nitrogen molecules
solution
we know that root mean square velocity of gas is Vrms = 
.......................1
mass of gas = M
universal gas constant = R
temperature = T
and we know mass of nitrogen = 28 g = 28 × 
kg
Vrms =
Vrms = 
Vrms = 515.22 m/s
root mean square velocity of nitrogen at 25°c is 515 m/s
correct option is b) 515 m/s
Answer:
The correct answer is option B, that is, western boundary currents.
Explanation:
The Western boundary currents get deflected by the eastern coastline of the continents. The western boundary currents refer to the deep, warm, narrow, and fast flowing currents, which produce on the west end of the ocean basins because of the western intensification. They conduct warm water from the tropics poleward. Some of the examples of western boundary currents are the Agulhas current, Gulf Stream, and the Kuroshio.
Answer:
The coefficient of superficial expansion is defined as the change in area per unit original area per unit change in temperature.
It depends upon temperature.
