        #Bomb calorimetry lab

        This notebook mimics a bomb calorimetry laboratory experiment.
        In each experiment a tablet of reactant is prepared and combusted in the calorimeter.
        During the experiment the temperature inside the calorimeter is monitored.

        ## Obejectives
        1. Calibration of the calorimeter
        2. Calculation of enthalpy of combustion of sucrose
        3. Calculation of enthalpy of combustion of napthalene

        ## Instructions
        1. Type your student ID
        2. Select a sample
        3. Click "Run Experiment"
        4. Perform at least 4 experiments per sample
