SOLVED:Zinc metal reacts with hydrochloric acid according to the balanced equation: Zn(s) 2 HCl(a q) ⟶ZnCl2(a q) H2(g) 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 ΔHrxn for this reaction as written. (Use 1.0  g / mL for the density of the solution and 4.18  J / g · ^∘ C as the specific heat capacity.

20. If 31.0g of zinc react with excess hydrochloric acid, how many grams of zinc chloride are produced? Be sure to check to see if the equation is balanced. Zn(s) + HCl (aq) →ZnCl2(aq) + H2(g) 20. If the 31.0g of zinc (from above) react with 15.4g of HCl, a) What is the theoretical yield (use your result from preceding question along with any new calculations you may need) b) Which is the limiting reactant c) What is the percent yield if 26.8g of zinc chloride are produced?
