A 2.490-g sample of cadmium metal completely reacts when placed in a coffee cup calorimeter that contains 75.0 mL of a dilute sulfuric acid solution (aqueous) (density of 1.03 g/mL) to produce hydrogen gas and dissolved cadmium sulfate. The chemical reaction is exothermic causing the temperature of the resulting aqueous solution to change from 21.5oC to 32.5oC. Write a balanced chemical equation for the chemical reaction that occurs. Find the enthalpy change, in kJ/mol, for the chemical reaction, assuming the specific...

A calorimeter contains 29.0 mL of water at 14.0 ∘C . When 1.30 g of X (a substance with a molar mass of 61.0 g/mol ) is added, it dissolves via the reaction X(s)+H2O(l)→X(aq) and the temperature of the solution increases to 27.0 ∘C . Calculate the enthalpy change, ΔH, for this reaction per mole of X. Assume that the specific heat of the resulting solution is equal to that of water [4.18 J/(g⋅∘C)], that density of water is 1.00...
