A metal X forms a water soluble salt XNO3. When an aqueous solution of XNO3 is added to common salt solution, then a white precipitate of compound Y is formed along with sodium nitrate solution. Metal X is said to be the best conductor of electricity and it does not evolve hydrogen when put in dilute hydrochloric acid.
(a) What is metal X?
(b) What is salt XNO3?
(c) Name the compound Y.
(d) Write the chemical equation of the reaction which takes place on reacting XN03 solution and common salt solution giving the physical states of all the reactants and products.
(e) What type of chemical reaction is illustrated by the above equation?
(a) Metal x is Silver(Ag).
(b) Salt XNO3 is Silver Nitrate(AgNO3)
(c) Compound Y is Silver Chloride (AgCl).
(d) the chemical equation:
AgNO3 (aq.) + NaCl (aq.) 
AgCl (s) + NaNO3 (aq.)
(e) Double Displacement Reaction takes place.
