Which of the following statements are correct?
i) \( CCl_4 \) undergoes hydrolysis easily.(ii) Diamond has directional covalent bonds.(iii)Fullerene is the thermodynamically most stable allotrope of carbon.(iv)Glass is a man-made silicate.
The standard electrode potentials \( E^\circ (V) \) for \( Li^+/Li \), \( Na^+/Na \) respectively are:
(1) −3.04, −2.714(2) −2.714, −3.04(3) −3.04, −3.04(4) −2.714, −2.714
Two statements are given below: Statement I: Molten NaCl is electrolysed using Pt electrodes. \( Cl_2 \) is liberated at the anode. Statement II: Aqueous CuSO\(_4\) is electrolysed using Pt electrodes. \( O_2 \) is liberated at the cathode. The correct answer is:
A current of 15.0 amperes is passed through a solution of CrCl2, for 45 minutes. The volume of Cl2 , (in I) obtained at the anode at 1 atm and 273 K is around (IF=96500 Cmol-1, At. wt. of Cl=35.5, R=0.082 L-atmK-1 mol-1)
