Reaction involving gold have been of particular interest to alchemists. Consider the following reactions
`{:(Au(OH)_(3)+4HCl,rarr,HAuCl_(4)+3H_(2)O",",,Delta H= -28 kcal),(AU(OH)_(3)+4HBR,rarr,HAuBr_(4)+3H_(2)O",",,DeltaH= -36.8 kcal):}`
In an experiment, there was an absorption of 0.44 kcal when one mole of `HAuBr_(4)` was mixed with 4 moles of HCl. Then, the fraction of `HAuBr_(4)` converted into `HAuCl_(4)` (percentage conservation)
