For my chemistry coursework i had to work out the enthalpy of decomposition of Sodium Hydrogencarbonate
to do this i had to do 2 experiments, then use the enthalpy changes of those to work out the enthalpy of decomposition of this 3rd reaction. i've worked it out but im struggling on the third bit - to draw a hess cycle for the reaction, i haven't got a clue what it looks like, can anyone help me on that bit?
heres what ive done upto now :

They are quite simple to draw and calculate, but hard to explain without diagrams, hope this may help:
the arrows point in the direction concerning whether it is endo or exo thermic.
