The element oxygen was prepared by Joseph Priestley in 1774 by heating mercury(II) oxide:
         HgO(s) → Hg(l) + 1/2O2(g),  ΔH° = 90.84 kJ/mol.
Estimate the temperature at which this reaction will become spontaneous under standard state conditions.
         S°(Hg) = 76.02 J/K·mol
         S°(O2) = 205.0 J/K·mol
         S°(HgO) = 70.29 J/K·mol
◦ 108 K
◦ 430 K
◦ 620 K
◦ 775 K
◦ 840 K

Each day had 10 decimal hours. Each hour had 100 decimal minutes. Due to lack of popularity, the metric clocks and calendars were ended in 1795, three years after they had been first marketed.
