QUESTION: 5
The ratio of the molar amounts of H₂S needed to precipitate the metal ions from 20 mL each of 1M Cd(NO₃)₂ and 0.5 M CuSO₄ is
Solution: As Cd2+ and Cu2+, both are dipositive ions but Cu2+ has one half of the concentration compared to that of the Cd2+. Thus, the molar amount of the H2S used to precipitate the metals ions Cd2+ and Cu2+ is 2 : 1.

QUESTION: 9

In which of the following case,does the reaction go farthest completion ?

Solution:

∵ higher the equilibrium constant , fastest the rate of reaction to completion.
for understanding this concept let see one example .
A + B ⇄ C + D
Equilibrium constant , K = [C][D]/[A][B]
For fastest completion of reaction numerator of RHS will be higher the denominator . Means higher the numberator , higher will be equilibrium constant and higher will be rate of reaction to completion.

Solution:
QUESTION: 14
The atomic radius of elements of which of these would be nearly same
Solution: The atomic radii of the d- block elements of a given series decrease with increase in atomic number but this decrease becomes small after midway. The decrease in atomic radii in the beginning, is due to an increase in nuclear charge from member to member which tends to reduce the size. At the same time, the addition of extra electrons to (n-1)d orbitals also provides the screening effect. As the number of d-electrons increases, the screening effect increases. Thus, there are operating two effects namely screening effect and nuclear charge effect which oppose each other. In the midway onwards of the series both these effects become nearly equal and thus, there is no change in atomic radii inspite of the fact that atomic number increases gradually.

QUESTION: 38
Modern Periodic Table is based on atomic no. of elements. The significance of atomic no. was proved by the experiment of
Solution: Moseley in 1912 measured the frequencies of X-rays emitted by a metal when bombarded with high speed electrons. He discovered that the square root of the frequency of the more prominent X-rays emitted by a metal was proportional to the atomic number and not the atomic weight of the atom of the metal. He thus concluded that atomic number was a more fundamental property of an element than its atomic weight. This forms tha basis of the modern periodic law.
