question 1 & 2
1. Magnesium solid reacts with aqueous hydrochloric acid to form the Mg2+ ion in solution. In an experiment, 60.0 mL of aqueous HCI was mixed with 0.1297 g of magnesium solid in a double Styrofoam cup calorimeter. The reaction caused the temperature of the substances in the calorimeter to rise 10.02°C. Assume the density and specific heat of the HCl solution is that of water, 1.00 g/mL and 4.184 J/g °C, respectively. The specific heat of...

A generic solid, X, has a molar mass of 72.6 g/mol. In a constant-pressure calorimeter, 16.6 g of X is dissolved in 365 g of water at 23.00 °C. X($) — X(aq) The temperature of the resulting solution rises to 27.80 °C. Assume the solution has the same specific heat as water, 4.184 J/(g°C), and that there is negligible heat loss to the surroundings. How much heat was absorbed by the solution? 9 kJ What is the enthalpy of the...
