Leaching of Al₂O₃ with alkali;

$\begin{array}{l}A{l}_2{O}_3\left(s\right)+2NaOH\left(aq\right)+3H_{2}O\left(l\right)\to 2Na\left[Al{\left(OH\right)}_4\right]\left(aq\right)\\ X\end{array}$

$\begin{array}{l}2Na\left[Al{\left(OH\right)}_4\right]\left(aq\right)+2C{O}_2\left(g\right)\to A{l}_2{O}_3.x{H}_{2}O\left(s\right)+2NaHC{O}_3\left(aq\right)\\ XYZ\end{array}$

Kindly go through the solution 

First reaction is EAS which will be given by that phenol derivative whose p-position is free for EAS reaction.

Eutrophication of water body results in loss of biodiversity.

$E_{M{n}^{+3}/M{n}^{+2}}^o=1.51V$

the strongest oxidizing agent have the highest reduction potential. So Mn³⁺ is the strongest oxidizing agent.

Cerium exists in two oxidation states (+3) and (+4)

  $\begin{array}{l}C{e}^{+4}+e^{-}\to C{e}^{+3}{E}^0=1.61V\\ C{e}^{+3}+3e^{-}\to Ce{E}^0=-2.336V\end{array}$  

It exist as Ce⁺⁴ and acts like a strong oxidizing agent by gaining electrons

In both reactions H₂O₂ act as reducing agent

In reaction (A)       HOCl – O.A

H₂O₂ – R.A

In reaction (B)       I₂ – O.A

H₂O₂ – R.A

Caprolactum is monomer of nylon-6

Isoprene is polymer of natural rubber

2 – chloro-1,3-butadiene or chloroprene is the polymer of neoprene which is a synthetic rubber

Acrylonitrite is one of the monomer of Buna-N

$C{H}_2=CH-CN$ Acrylonitrile

Freundlich adsorption isotherm

$\frac{x}{m}=k{p}^{1/n}$            

$log\frac{x}{m}=\frac{1}{n}logp+logk$           

Comparing with y = mx + C

so, slope of given graph is $\frac{1}{n}$  whose value varies from 0 to 1.
