Question 19 O out of 5 points In the reaction, Zn + 2 HCI - ZnCl2 + H2, 25.0 grams of Zn are reacted with 17.5 g of HCI. Which substance is the limiting reactant?
You want to determine AH for the reaction Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g) To do so, you first determine the heat capacity of a calorimeter using the following reaction, whose AH is known: NaOH(aq) + HCl(aq) + NaCl(aq) + H2O(1) -57.32 kJ (a) Calculate the heat capacity of the calorimeter from these data: Amounts used: 50.0 mL of 2.00 M HCl and 50.0 mL of 2.00 M NaOH Initial T of both solutions: 16.9°C Maximum T recorded during...
8) Balance the equation for the following reaction. Zn(s) + HCl(1) → ZnCl2(aq) + H2(g) -
Zinc metal reacts with hydrochloric acid according to the following balanced equation. Zn(s)+2HCl(aq)?ZnCl2(aq)+H2(g) When 0.112 g of Zn(s) is combined with enough HCl to make 54.9 mL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 21.7 ?C to 23.9 ?C. Find ?Hrxn 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.) Answer should be in kJ/mol.
