(a) Name X and Y
(b) Write the chemical equation of the reaction of metal X with
(i) hydrochloric acid, and
(ii) sodium hydroxide solution.
(b) (i) When hydrochloric acid reacts with Zn, hydrogen gas and zinc chloride are formed Zn + 2HCl ⇨ ZnCl2 + H2
(ii) Sodium hydroxide gives hydrogen gas and sodium zincate when reacts with zinc metal.
2NaOH + Zn ⇨ Na2ZnO2 + H2
