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)`

Answer

C

Explanation

`(A) :Zn + 2HCl to ZnCl_2 +H_2`
1 mole of Zn produces 2 g of `H_2`
5 mole of Zn will produce 10 g of `H_2`
(B): `C_(70)H_(22)`
Molar mas = 862
Mass of atoms = `862 // 6.023xx10^(23)`
`= 1.43xx10^(-21)g`
( C) : 70 g of `Cl_2 = 6.023 xx10^(23)` molecules
3.5 g of `Cl_2 = 3.01 xx10^(22)` molecules
(D) Molar mass of `SO_2 = 64 = 1` mole
64 g of `SO_2 = 6.023 xx10^(23)` molecules
