A student measures out 100.0ml of 1.00 M HCl and places it in a styrofoam cup. The temperature od HCl is 22.3 C. She then addes 1.002g og MgO to the cup. The temperature rises to 29.7 C.
a) Determine the enthalpy of he reaction. Assume that the density and the specific heat of the solution are the same as water. Include the correct sign.
b) Determine the change of enthalpy for the reaction in units of KJ/mol og MgO. Include the correct sing.
