When Magnesium Reacts with Hydrochloric Acid, Aqueous Magnesium Chloride and Hydrogen

question 164

Short Answer

When magnesium reacts with hydrochloric acid, aqueous magnesium chloride and hydrogen gas are produced.Suppose 0.120 g Mg react with the HCl in a 75.000 g acidic solution contained in a calorimeter.The temperature increases by 6.03 °\degree C.Calculate the Δ\Delta Hrxn of Mg with HCl in kJ/mol.Assume the specific heats of the solution and of the empty calorimeter are 4.18 J/g . °\degree C) and 64.4 J/ °\degree C, respectively.
