enthalpy - Crunch Chemistry

Enthalpy cycles, Hess cycles, thermochemical cycles

What is enthalpy exactly? An enthalpy change is the heat transferred at constant pressure by a chemical reaction Heat changes

Determining either the enthalpy change of neutralisation, or the enthalpy change for a classic displacement reaction (they are pretty much

You can calculate an experimental value for the enthalpy change of combustion for a fuel very simply – this is

Thermochemistry is all about the energy changes that happen alongside chemical reactions. Chemical reactions either release heat (exothermic) or

Why does water freeze when you place it in a freezer? Certainly not because the freezer sucks the heat out
