7. 2.500 grams of metal X (molar mass = 65.39 g/mole) was reacted with 100.0 mL of a 1.500 M HCI solution in a coffee cup calorimeter. The temperature went from 12.50 °C to 40.50 °C. Determine the reaction enthalpy per mole of metal X. The specific heat of the solution is 4.184 J/g °C. Assume a solution density of 1.00 g/mL and a perfect system.

Using the phase diagram here, at what temperature will a solution of 36 mole % A begin to boil? Temperature-Composition Phase Diagram for Compositions of Compounds A and B 500 450 400 350 300 250 200 150 100 50 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 Composition (mole fraction B) Temperature (°C)

Calculate the change in enthalpy ΔH for 100 kg of material undergoing the following temperature and phase changes.  Show your calculations in detail (including the integrations) type them out in word. Ammonium sulfate (crystalline) heated from 10 °C to 40 ° Heat Capacity, i think i did it wrong, i used the values on the bottom table, i think im supposed to use value from the top...

Calculate the freezing point of a 2.0m solution of NaCl in water? Remember that NaCl is an electrolyte. The normal freezing point of pure water is 0.00°C. Kf(water) =1.86°C/m

Please help find Ccal. I was not sure what information is required so I have attached it below.
