Homework Help: Calorimetry calibration

  1. Nov 22, 2011 #1
    1. The problem statement, all variables and given/known data
    in the reaction 10mL of 1M NaOH + 5mL of 1M HCl (adiabatic)
    given change in temp=2.1°C (temp initial is the temp of NaOH, temp final is acquired after the addition of HCl)
    find: qrxn, qcal, Ccal

    2. Relevant equations
    qrxn = -qca
    Ccal = qcal/∆T

    3. The attempt at a solution
    sorry but i'm really at total lost here. i took the prerequisite chemistry 4semesters ago
    the only thing that i can find in searching are the formula on how to solve them but i can't quite get how to use those given only the dT

    You are given much more - you know the volumes, you know concentrations (that gives amounts of acid and base), assuming density of 1 g/mL (often done for not too concentrated water solutions) you have also total mass. Plenty of data to solve the question.
