    Ok i was reading some study notes and they said that you can not calculate the enthalpy of the reactants so i gave it a go to prove it wrong.
    Now there is only a change in enthalpy because their is a change in energy and only a change in energy because of a change in temperature right? So(assuming measurements of liquid) wouldnt it be possible to work out the energy of the reactants due to initial temperature and mass somehow. Thanks


    just wondering

    Enthalpy is an arbitrary measurement of 'energy' and therefore only a change can be measured with the initial state being taken as the reference point.


    everything is mathematical.
