The electronic configuration of Chlorine is 1s2 2s2 2p6 3s2 3p5.
There are three energy levels in chlorine
First energy level is n=1 has 1s2 so total 2 electrons
Second energy level is n=2, 2s2 2p6 so total 2+6= 8 electrons
Third has 3s2 3p5 electrons just 7 total... p can contain 6 electrons but only 5 are present. So the third level has lesser number of electrons than that can be filled
Answer:
Explanation:
It is possible to answer this question knowing Hess's law that says you can sum half-reactions enthalpy cahnge to obtain enthalpy change of the total reaction. Using the reactions:
<em>(1) </em>2NO(g) → N₂(g)+O₂(g) ΔH = -180,6 kJ
<em>(2) </em>N₂(g) + O₂(g) + Cl₂(g) → 2NOCl(g) ΔH = +103,4 kJ
The reverse reactions of (1) and (2) are:
<u>N₂(g)+O₂(g)</u> → 2NO(g) ΔH = +180,6 kJ
2NOCl(g) → <u>N₂(g) + O₂(g)</u> + Cl₂(g) ΔH = -103,4 kJ
The sum of these reactions is:
2NOCl(g) → 2NO(g) + Cl₂(g) ΔH = +180,6 kJ -103,4 kJ = <em>77,2 kJ</em>

Answer : Option B) The equilibrium will shift to the left to such an extent that it leads to the precipitation of solid soap.
Explanation : The equilibrium will tend to shift to left because addition of sodium chloride salt will lead to precipitate the soap as a product. The volume increase in the sodium ions because of sodium chloride addition will generate the more amount of solid soap.
Answer:
Solid magnesium chloride is a non-conductor of electricity because the ions aren't free to move. However, it undergoes electrolysis when the ions become free on melting. Magnesium chloride dissolves in water to give a faintly acidic solution (pH = or 6).
