Hess's law
ΔH_solution = ΔH_lattice + ΔH_hydration
4 = 788 + ΔH_hydration
ΔH_hydration = -784 kJ mol? ¹

At $\frac{dy}{\sqrt[]{1-y^2}}+\frac{dx}{\sqrt[]{1-x^2}}=0\Rightarrow {\mathrm{s}\mathrm{i}\mathrm{n}}^{-1}?y+{\mathrm{s}\mathrm{i}\mathrm{n}}^{-1}?x=c$ $\frac{}{\text{exception 25:}}\frac{}{\text{exception 25:}}{}^{}{}^{}$

Hence $x=\frac{1}{2},y=\frac{\sqrt[]{3}}{2}\Rightarrow c=\frac{\pi }{2}\Rightarrow {\mathrm{s}\mathrm{i}\mathrm{n}}^{-1}?y={\mathrm{c}\mathrm{o}\mathrm{s}}^{-1}?x$ $\frac{}{}\frac{\text{exception 25:}}{}\frac{}{}{}^{}{}^{}$

In isoelectronic species nuclear charge can be approximated as
Nuclear charge ≈ z / no. of electrons
Al³? Mg²? Na? F? O²? N³?
Nuclear Charge: 13/10 12/10 11/10 9/10 8/10 7/10
Minimum nuclear charge is in N³? and maximum is in Al³?
So order should be
Al³? < Mg²? < Na? < F? < O²? < N³?

Using VSEPR, L.P - B.P repulsion we can safely say that CH? should have the highest bond angle among the given

KNO? , HCl and NaCl are strong electrolytes for these electrolytes of Λ_m with √c will be liner which can be given as
Λ_m = Λ? _m - A√c for strong electrolyte
Since given variation is not linear it has to be a weak electrolyte
CH? COOH is a weak electrolyte

Gas + Solid? GS? H = -ve
Adsorbed gas
Adsorption of gas is an exothermic process. Increase in temperature reduces the extent of adsorption.

In FCC octahedral voids are present at the edge centers and body center

Consider a diagonal projected form edge centre passing through the body centre
Distance between octahedral voids = √2a/2 = a/√2

$\mathrm{}{f}^{\mathrm{\text{'}}}\left(x\right)=x\left(\pi -{\mathrm{c}\mathrm{o}\mathrm{s}}^{-1}?(\mathrm{s}\mathrm{i}\mathrm{n}?|x\left|\right)\right)=x\left(\pi -\left(\frac{\pi }{2}-{\mathrm{s}\mathrm{i}\mathrm{n}}^{-1}?(\mathrm{s}\mathrm{i}\mathrm{n}?|x\left|\right)\right)\right)=x\left(\frac{\pi }{2}+\left|x\right|\right)$

$f\left(x\right)=\left\{\begin{array}{ll}x\left(\frac{\pi }{2}+x\right)& x\ge 0\\ x\left(\frac{\pi }{2}-x\right)& x<0\end{array}\right.$

$f^{\mathrm{\text{'}}}\left(x\right)=\left\{\begin{array}{ll}\frac{\pi }{2}+2x& x\ge 0\\ \frac{\pi }{2}-2x& x<0\end{array}\right.$  is increasing in $f^{\mathrm{\text{'}}}\left(x\right)$ ${}^{}$ and decreasing in $\left(0,\frac{\pi }{2}\right)$
