Write a balanced chemical equation for â¦ Zinc reacts with hydrochloric acid to produce zinc chloride and 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 21.7âC to 24.1âC.Find ÎHrxn for this reaction as written. Zn(s)+2HCl(aq)âZnCl2(aq)+H2(g)? When zinc metal is submerged into a quantity of aqueous HCl, the following reaction occurs (Figure 5.4 "Zinc Metal plus Hydrochloric Acid"):Zn(s) + 2HCl(aq) â H 2 (g) + ZnCl 2 (aq). 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. Similar to magnesium, zinc also reacts with hydrochloric acid to form hydrogen gas according to the balanced equation below.
