Potassium chlorate is prepared by electrolysis  of KCl in basic solution as shown by following equation.

6 OH^- + Cl^- $Cl{O}_3^{-}$ ->  + 3H₂O + 6e^-

A current of xA has to be passed for 10h to produce 10.0g of potassium chlorate. The value of x is__________. (Nearest Integer)

(Molar mass of KClO₃ = 122.6g mol^-1, F = 96500C)

The standard enthalpy of combustion at 25°C of hydrogen, cyclohexene (C₆H₁₀) and cyclohexane (C₆H₁₂) are –241, –3800 and –3920 kJ mol–1 respectively. Calculate the standard enthalpy of hydrogenation of cyclohexene.

HCP crystal is made of A ions and B ions are arranged in 2/3rd of octahedral voids. The simplest formula of compound is :-
