Classify the following species into Lewis acids and Lewis bases: O${{H}^{-}}$,${{F}^{-}}$,${{H}^{+}}$,B${{F}
{3}}$ Calculate the pH of a solution in which 0.4 g of NaOH is dissolved in water to give 200 mL of solution.
6.${{H}_{2}}$0 can act both as Bronsted arid and base. Write it’s corresponding conjugate base and conjugate arid.

© As this is an exothermic reaction, on increasing
the temperature, the reaction will move in reverse direction. This results in decrease in concentration of N${{H}{3}}$
(d) On increasing the concentration of ${{N}
{2}}$(g) and ${{H}{2}}$(g), the yield of N${{H}{3}}$ will increase.
(e) On increasing the pressure, the reaction will
move in forward reaction in which number of moles of gas or pressure decreases.
