Answer (A) Zinc chloride + Hydrogen. hydrochloric acid + zinc carbonate arrow zinc chloride + carbon dioxide + water 2HCl(aq) + ZnCO3(s) arrow ZnCl2(aq) + CO2(g) + H2O(l) Zinc + Hydrochloric acid ... chemistry. Relevance. 10 years ago. If 5.62 g of zinc reacts with excess hydrochloric acid, what will be the temperature of the hydrogen gas produced at a pressure of 780 mm Hg, a volume of 15.2 L? Thanks. D. Zinc. Favorite Answer. C) Zn2+ (aq) + H2 (g) → ZnS (s) + 2 H+ (aq). share | improve this question | follow | asked Apr 4 '18 at 21:51. For example, why can zinc displace hydrogen from hydrochloric acid, but not from water? MEDIUM. A) ZnCl2 (aq) + H2 (g) → ZnS (s) + 2 HCl (aq). C. Zinc + Hydrogen. 11 1 1 bronze badge $\endgroup$ $\begingroup$ Note that $\ce{Zn + H2O -> Zn(OH)2 + H2}$ when hot water is used. B) Zn (s) + 2 HCl (aq) → ZnCl2 (aq) + H2 (g). Zinc + Hydrochloric acid → A. Zinc chloride + Hydrogen. 3 Answers. Alan Tam Alan Tam. Lv 5. BHC Steve . Answer Save. However, the $\ce{Zn(OH)2}$ layer formed doesn't allow the reaction to proceed. D) Zn (s) + 2 H+ (aq) → Zn2+ (aq) + H2 (g). B. Zinc + chlorine + Hydrogen. acid-base. Reaction of zinc, potassium dichromate and hydrochloric acid 3Zn + K 2 Cr 2 O 7 + 14HCl → 3ZnCl 2 + 2CrCl 3 + 2KCl + 7H 2 O As a result of the reaction of zinc (Zn), potassium dichromate (K 2 Cr 2 O 7 ) and hydrochloric acid (HCl) produces zinc chloride (ZnCl 2 ), chromium(iii) chloride (CrCl 3 ), potassium chloride (KCl), water (H 2 O) E) none of these. The net ionic equation for the reaction between zinc and hydrochloric acid solution is.
