Question

Please help with details and steps, i am fairly loss withenthalpy and internal energy stuff...so the more details the more iwill award u with the 15000 points

In a calorimeter (e.g., a styrofoam coffee cup, which essentially prevents the flow of heat to or from the surroundings), 100.0 mL of 1.00 M NaOH and 100.0 mL of 1.00 M HCl are mixed and reacted. Both solutions were originally at 24.6 degree C. After the reaction, the final temperature of the solution is 31.3 degree C. Since the solutions are dilute, assume that all the solutions have the density and specific heat capacity of water, each rounded to two significant figures. The heat capacity of the calorimeter is insignificant. Is this reaction endothermic or exothermic? Justify your choice If heat were absorbed by this reaction in this situation, what would happen to the temperature? What is the amount of heat produced or absorbed by the reaction? Be sure to get the sign correct. What is the enthalpy change for this reaction? Express this change in units of kJ/mole H2O produced by the reaction. Be sure to get the sign correct.
