Match the coloumn I with coloum II and mark the appropriate choice.

Options

A. `(A) to (ii), (B) to (i), (C) to (iv), (D) to (iii)`
B. `(A) to (i), (B) to (ii), (C) to (iii), (D) to (iv)`
C. `(A) to (iv), (B) to (iii), (C) to (i), (D) to (ii)`
D. `(A) to (iv), (B) to (iii), (C) to (ii), (D) to (i)`

Explanation

`(A) : Zn + 2HCl to ZnCl_2 + H_2`
1 mol of Zn produces 2 g of `H_2`
0.5 mole of Zn will produce 1g of `H_2`
(B) : `C_70H_22`
Molar mass =862
Mass of atoms = `862//6.023xx10^23=1.43xx10^(-21)` g
35.3 g of `Cl_2=3.01xx10^23` molecules
(D) : Molar mass of `SO_2` = 64 = 1 mole
64g of `SO_2=6.023xx10^23` molecules
