Calamine -> ZnCO₃    

The carbonyl compounds which contain at least two a-hydrogen will give aldol condensation.

Suspension of slaked lime in water is known as milk of lime

Crude sodium chloride obtained by crystallisation of brine solution contains CaSO4, Na2SO4 and MgCl2

Beryllium salts are easily hydrolysed 

Gypsum : CaSO₄ . 2H₂O

Plaster of Paris : CaSO₄ .1/2HO₂

Kindly consider the following figure

PbS + 4H₂O₂->PbSO₄ + 4H₂O.

Kindly consider the following figure

Work depends on the path followed by the system so work is path function.

Depletion of ozone is due to CF₂Cl₂

Kindly go through the solution

Since VReal > Videal

So, Z = Real ideal V

$B_2\to \sigma 1s^2{\sigma }^{*}1s^2\sigma 2s^2{\sigma }^{*}2s^2\pi 2p_x^1=\pi 2p_y^1$
