(a) Silver (Ag) is a conductor of electricity that does not produce hydrogen when exposed to dilute hydrochloric acid.
(b) Silver nitrate (AgNO3) is XNO3 which reacts with NaCl (common salt) to give a white precipitate
(c) Silver chloride (AgCl), a white precipitate produced by the interaction of silver nitrate and sodium chloride, is the chemical Y.
(d) Chemical equation for the reaction involved is:
AgNO3(aq) + NaCl (aq)→ AgCl (s) + NaNO3 (aq)
(e) A double displacement reaction occurs when two compounds react and the positive and negative ions from the two reactants replace each other, resulting in the formation of new molecules.
