Explanation:
In the box on the left there are 8 Cl⁻ ions and 8 Na⁺ ions.
The dissociaton equation for NaCl(aq) is:
- NaCl (aq) → Na⁺ (aq) + Cl⁻(aq)
The dissociation equation for CaCl₂ (aq) is:
- CaCl₂ (aq) → Ca²⁺ (aq) + 2Cl⁻(aq)
A 0.10MCaCl₂ (aq) solution will have half the number of CaCl₂ units as the number of NaCl units in a 0.20M NaCl (aq) solution.
Thus, while the 0.20M NaCl (aq) solution yields 8 ions of Na⁺ and 8 ions of Cl⁻, the 0.10MCaCl₂ (aq) solution will yield 4 ions of Ca²⁺ (half because the concentration if half) and 8 ions of Cl⁻ (first take half and then multiply by 2 because the dissociation reaction).
Thus, your drawing must show 4 dots representing Ca²⁺ ions and 8 dots representing Cl⁻ ions in the box on the right.

Explanation:
Lone pairs are present on nitrogen atoms of both pyridine and pyrrole.
In pyrrole, the electron pair on nitrogen is involved in resonance and hence does not available for bonding. Therefore, pyrrole does not possess basic character and remains unreactive towards HCl.
In case of pyridine, as 6 pi electrons are present in the ring, so, electron pair of nitrogen does not participate in resonance. So, because of presence of lone pair, pyridine possess basic character and hence, reacts readily reacts with HCl.
