Write brief answers to the following questions:
1. Does the solubility of a substance change with temperature? Explain with the help of an example.
-dependent property. The solubility generally increases with an increase in . For example, you can dissolve more in hot water than cold water.
2. Classify each of the following on the basis of their atomicity.
(a). \(F_2\) (b). \(NO_2\) (c). \(N_2O\) (d). \(C_2H_6\) (e). \(P_4\) (f). \(H_2O_2\) (g). \(P_4O_1{_0}\) (H). \(O_3\) (i). HCl (j). \(CH_4\) (k). He (l). Ag.

(a). 2 (b). 3 (c). 3 (d). 8 (e). 4 (f). 4 (g). (h). 3 (i). 2 (j). 5.
(k). 1 (Noble gases do not combine and exist as gases).
(l). . It is difficult to talk about the atomicity of metals as any measurable quantity will contain millions of atoms bound by metallic bond (about which you would learn later).
