An electron configuration that is farther away from 8 or 1, an electron valence that is either closer to 8 or 1 will become less stable. This is because they will either by trying hard to loose an electron to have a full 8 or gain one to become. Full 8 valence
Answer: V = 6.30L
PV = nRT
15°C = 15+273 = 288K
3.75*V = 1.50*0.082057*288
V = (1.50*0.082057*288)/3.75
V = 6.30L

A reagent is a compound that is used for the detection of the absence or presence of another substance.
<h3>What are reagents?</h3>
Your information is incomplete as the available reagents aren't given. Therefore, an overview will be given.
Reagents are the integral part of a chemical reaction as they facilitate a reaction. A reagent is usually used tests.
Some typical examples of reagents include Tollens reagent, Fehling's reagent, Million's reagent, etc.

Answer:
The balanced equations for those dissociations are:
Ba(OH)₂(aq) → Ba²⁺(aq) + 2OH⁻ (aq)
H₂SO₄ (aq) → 2H⁺(aq) + SO₄⁻²(aq)
Explanation:
As a strong base, the barium hidroxide gives OH⁻ to the solution
As a strong acid, the sulfuric acid gives H⁺ to the solution
Ba(OH)₂, is a strong base so the dissociation is complete.
H₂SO₄ is considerd a strong acid, but only the first deprotonation is strong.
The second proton that is released, has a weak dissociation.
H₂SO₄ (aq) → H⁺(aq) + HSO₄⁻(aq)
HSO₄⁻(aq) ⇄ H⁺ (aq) + SO₄⁻² (aq) Ka
Here we have to choose the way which is not the common way to judge the quality of the air in a particular area.
The measuring the amount of precipitation in the area is not the common way to determine air quality in an area.
The acidity of the rain causes due to the excess amount of CO₂ and SO₂ in an area. Both the gases cause pollution.
The measuring of the amount of a particular gas element is a renowned way to determine the pollution level of an area.
The ozone is a harmful gas so the measuring of its amount in ground level can identify the level of pollution in the particular area.
