Zinc metal reacts with hydrochloric acid according to the balanced equation: 2HCl (aq) + Zn (s) → ZnCl2 (aq) + H2 (g) When 0.103 g of zinc is combined with enough HCl to make 50.0 mL of solution in a coffee-cup calorimeter, all of the zinc reacts, resulting the temperature of the solution from 22.5oC to 23.7 oC. Find ΔHrxn for this reaction as written. The density, and the specific heat of the solution are 1.00 g/mL and 4.184 J/g...

A. Hydrochloric Acid Solution and pH 1. Write the balanced chemical reaction for the dissociation of the hydrochloric acid. 2. Refer to the procedure for A to determine the concentrations of the solutions of hydrochloric acid. Remember to use MiV1-MV. Show work for trial 1. 3. Calculate the theoretical pH of each hydrochloric acid solution. Recall that hydrochloric acid is a strong acid, suggesting complete dissociation, so that the equation pH log (HO) can be used (equation 3). Show work...
