    Lab report The enthalpy change of a chemical reaction
    The enthalpy change of a chemical reaction
    I found the mass of the empty calorimeter to be: 11.600g, Initial temp in the calorimeter was: 21.00 degrees celcuis, max. temp in the calorimeter from the reaction was: 29.27 degrees celcuis. I can't calculate delta T as Tmaximun-Tinitial

    I don't quite understand your issue. I find it strange you can't do the subtraction, so that means I am not understanding something in your question...

    In that equation, if I am understanding your question correctly, delta T refers to change in temperature; so it is just one variable you need to enter into the equation, which is 8.27 kelvin or Celsius because they are both the same, 1 for 1.

    Obviously T initial is 21.0 degrees and T maximum is 29.27 degrees. So delta T is just the change in temp = 8.27 C.

    Hope that helps, and that I am on the same path of thought as you.

How do I find the enthalpy change in a calorimeter? [ 1 Answers ]

A calorimeter contains 30.0 mL of water at 12.0 C. When 1.60 g of X (a substance with a molar mass of 45.0 g/mol) is added, it dissolves via the reaction X (s) + H2O (l) → X (aq) and the temperature of the solution increases to 28.5 C. Calculate the enthalpy change, Delta H, for this...
