Answer:
Acid rain, like all acids, generates dissolution of chemical compounds, and reacts together with bases to be able to carry out oxide reduction reactions, which by deduction is very likely to form new substances as a result of the dissolution or acid erosion caused.
Explanation:
Acid rain is more likely to occur in large cities or large sources of pollution, since the excess of carbon dioxide in the atmosphere causes it to increase its partial pressure in a condensed way in the clouds, this is how then this cloud when being loaded with water and then generating the rain drags these masses of condensed carbon dioxide in the form of acid rain.
The degree of acidity is directly proportional to the amount of partial pressure of carbon dioxide in the atmosphere.

Answer: -
H₂ will diffuse the fastest.
Explanation: -
According to Graham's Law of Diffusion
The rate of diffusion is inversely proportional to the square root of it's density or molar mass. So the lower the molar mass faster the rate of diffusion.
Molar mass of Ne = 20 g / mol
Molar mass of CH₄ = 12 x 1 + 1 x 4 = 16 g /mol
Molar mass of Ar = 40g / mol
Molar mass of H₂ = 1 x 2 = 2 g / mol
Thus H₂ will diffuse the fastest.
Answer:
Explanation:
To find the concentration; let's first compute the average density and the average atomic weight.
For the average density 
; we have:
The average atomic weight is:
So; in terms of vanadium, the Concentration of iron is:
From a unit cell volume 
where;
= number of Avogadro constant.
SO; replacing with 
; with 
; 
with 
and
with 
Then:
