Solution:
QUESTION: 21
In the saphalerite (ZnS) structure, 
ions form a face- centered cubic lattice. Then 
ions are present on the body diagonals at
ions form a face- centered cubic lattice. Then ions are present on the body diagonals at
Solution:
QUESTION: 22
Which substance shows anti-ferromagnetism ?
Solution:
QUESTION: 23
An electron has principal quantum number 3. The number of its (i) sub-shells and (ii) orbitals would be respectively
Solution:
Here principal quantum number =3 as the values of azimuthal quantum number = 0 to n-1 so the number of Subshells = 0,1,2(s p d) as per the formula, number of orbitals in a given principal quantum number = n^2 where n=principal quantum number so the answer is 3 and 9

Which of the following molecule is linear ?
Solution:
QUESTION: 25
The number of water molecules present in a drop of water (volume 0.0018 ml) at room temperature is
Solution:
QUESTION: 26
Heat of neutralisation is least when
Solution:
QUESTION: 27
Starting with one mole of 
and two moles of 
, the equilibrium for the formation of 
was established at a certain temperature. If V is the volume of the vessel and 2x is the number of moles of present, the equilibrium constant will be
and two moles of , the equilibrium for the formation of was established at a certain temperature. If V is the volume of the vessel and 2x is the number of moles of present, the equilibrium constant will be
Solution:
QUESTION: 28
The atomic numbers of other elements which lie in the same group as the tenth element in the periodic table are

Solution:
QUESTION: 30
Which one of the following removes temporary hardness of water ?
Solution:
Explanation:
There are a number of methods to remove the hardness present in water. When any of these methods are followed, hard water gets converted into soft water.
Some of the methods to remove hardness from water are:
1. Chemical Process of Boiling Hard Water.
2. Adding Slaked Lime (Clark's Process).
3. Adding Washing Soda
4. Calgon Process
5. Ion Exchange Process
6. Using Ion Exchange Resins.
Hence, in above given question we can remove the temporary hardness of water by adding slaked lime.
