Hydrogen gas is produced: Zn + 2HCl â ZnCl2 + H2â + Î´Q   Zinc (Zn) reacts with Hydrochloric Acid (HCl) to produce Zinc Chloride (ZnCl2), Hydrogen Gas (H2), and He â¦ at. 6 people found this useful.
Reaction of zinc with air. Zinc metal tarnishes in moist air. Zinc metal burns in air to form the white zinc(II) oxide, a material that tirns yellow on prolonged heating.2Zn(s) + O 2 (g) â 2ZnO(s) [white].eaction of zinc with acids. Zinc metal dissolves slowly in dilute sulphuric acid to form solutions containing the aquated Zn(II) ion together with hydrogen gas, H 2. In practice, the Zn(II) is present as the complex ion [Zn(OH 2) 6 ] 2+ . Zn(s) + H 2 SO 4 (aq) â Zn 2+ (aq) + SO 4 2- (aq) + H 2 (g).
