The Hydrogen gas is collected and then ignited to hear a "pop noise. When zinc is added to copper (II) sulfate, a single displacement reaction will take place, creating a solid, copper, and zinc sulfate. Zn reacts with hydrochloric acid in a single displacement reaction. Learn about the reaction and see examples. This reaction is a single displacement reaction. The zinc replaces the hydrogen: Zn + 2 HCl → ZnCl 2 + H 2 Here is another example of a single displacement reaction : In the single-displacement reaction, what happened to the temperature and pressure immediately after adding the zinc? Then explain the different reactions of the hydrogen gas. Therefore, the option (a) is correct which represented as a single replacement reaction takes place because zinc is more reactive than hydrogen. In a chemical reaction, zinc metal is placed into a solution of hydrochloric acid, and zinc chloride is produced along with hydrogen gas. In order to liberate a hydrogen ion from $\ce{H2O}$, this must occur: $$\ce{H2O -> H^+ + OH^-}$$ The products of such a reaction are the metal hydroxide and hydrogen gas. For example, zinc metal reacts with hydrochloric acid producing zinc chloride and hydrogen gas. See here: Zinc in a single displacement reaction with hydrochloric acid [closed]. Generally, Stocks move the index. Therefore, zinc barely replaces hydrogen in water. For example, the ionic equation for the reaction of magnesium with hydrochloric acid is: 2H + (aq) + Mg(s) → Mg 2+ (aq) + H 2 (g) rev 2021.1.11.38289, The best answers are voted up and rise to the top, Chemistry Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us.
