Here are the answers to your questions: a) (i) Gas M: Ammonia* (NH_3) (ii) Solution F: Ammonium chloride* (NH_4Cl) (iii) Solid X: Sodium bicarbonate* (NaHCO_3) (iv) The product L: Calcium chloride* (CaCl_2) b) The reaction in chamber K is between calcium hydroxide (from heating limestone and adding water) and ammonium chloride (Solution F). Ca(OH)_2(aq) + 2NH_4Cl(aq) CaCl_2(aq) + 2NH_3(g) + 2H_2O(l) c) Two raw materials used in the Solvay process are: Brine* (sodium chloride solution) Limestone* (calcium carbonate) d) (i) One substance recycled in the Solvay process is ammonia* (NH_3). (ii) Carbon (IV) oxide (CO_2) is used as a fire extinguisher because: It is denser than air*, forming a blanket over the fire and cutting off the oxygen supply. It is non-combustible* and does not support combustion. (iii) Lead carbonate is not reacted with dilute H_2SO_4 in the laboratory preparation of carbon (IV) oxide because the product, lead sulfate* (PbSO_4), is insoluble. It forms a protective layer on the surface of the lead carbonate, preventing further reaction with the acid and stopping the production of CO_2. 3. a) Graham's Law of Diffusion states that the rate of diffusion or effusion of a gas is inversely proportional to the square root of its molar mass (or density).
