Zinc metal reacts with hydrochloric acid, according to the chemical equation below. Aqueous hydrochloric acid (HCl) reacts with solid zinc to produce hydrogen gas and aqueous zinc chloride. The equation is: Zinc + Hydrochloric Acid(Dilute)→ Zinc Chloride + Hydrogen gas When 0.116g of Zn(s) is combined with enough HCl to make 51.7mL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 21.7∘C to 24.1∘C.Find ΔHrxn for this reaction as written. Zn (s) + 2 HCl (aq) → ZnCl2 (aq) + H2 (g) Tina added 0.146 mole of hydrochloric acid solution to 0.135 mole of zinc in a beaker and waited several minutes for the reaction to complete. When sodium carbonate reacts with hydrochloric acid the gas evolved is: (a) carbon dioxide (b) chlorine (c) hydrogen (d) oxygen. R e a s o n: The reaction between zinc and hydrochloric acid is , Z n + 2 H C l → Z n C l 2 + H 2 This reaction is known as single replacement reaction, where zinc metal displaces the hydrogen to form hydrogen gas and zinc chloride, a salt. 35. (b) granulated zinc reacts with caustic soda. Calculate the molar mass of zinc using the data provided in the table.Zn + 2HCl -> ZnCl2 + H2 Mass of metal sample 130.76 g Number of moles of H2 2.000 mol “Looking for a Similar Assignment? Write a balanced chemical equation for … Zinc metal reacts with hydrochloric acid according to the balanced equation: When 0.103 g of Zn(s) is combined with enough HCl to make 50.0 mL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 22.5 C to 23.7 C. Find Hrxn for this reaction as written. Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)? Zinc metal reacts with hydrochloric acid according to this balanced equation. Similar to magnesium, zinc also reacts with hydrochloric acid to form hydrogen gas according to the balanced equation below. 34. Name the products formed in each case when (a) hydrochloric acid reacts with caustic soda. When zinc metal reacts with dilute hydrochloric acid, the gas evolved is (a) carbon dioxide (b) chlorine (c) hydrogen (d) oxygen.
