32:- Which of the following is not a p-block element
p-block elements are located in groups 13-18 of the periodic table.
(a) Sn (Tin) is in Group 14, a p-block element.
(b) Al (Aluminum) is in Group 13, a p-block element.
(c) Mg (Magnesium) is in Group 2, which is an s-block element*.
(d) Pb (Lead) is in Group 14, a p-block element.
The correct option is (c).
$$\boxed{\text{c) Mg}}$$
33:- The number of elements in the second period of the periodic table is
The second period of the periodic table contains elements from Lithium (Li) to Neon (Ne).
These elements are: Li, Be, B, C, N, O, F, Ne.
Counting these elements, there are 8 elements in total.
The correct option is (a).
$$\boxed{\text{a) 8}}$$
34:- tribasic acid is
A tribasic acid* is an acid that can donate three protons ($H^+$ ions) per molecule in an aqueous solution.
(a) $H_3PO_4$ (Phosphoric acid) has three ionizable hydrogen atoms, making it a tribasic acid.
(b) $H_3PO_2$ (Hypophosphorous acid) has only one ionizable hydrogen atom, making it a monobasic acid.
(c) $HPO_3$ (Metaphosphoric acid) has one ionizable hydrogen atom, making it a monobasic acid.
(d) pbH2O is not a standard acid formula.
The correct option is (a).
$$\boxed{\text{a) H3PO4}}$$
35:- Highest diffusion capacity is found in
According to Graham's Law of Diffusion*, the rate of diffusion of a gas is inversely proportional to the square root of its molar mass. This means gases with lower molar masses diffuse faster.
Molar mass of He (Helium) $\approx 4.00 \text{ g/mol}$.
Molar mass of Ne (Neon) $\approx 20.18 \text{ g/mol}$.
Among the given options, Helium has the lowest molar mass, and therefore, the highest diffusion capacity.
The correct option is (a).
$$\boxed{\text{a) He}}$$
