When heated, mercury(II) oxide decomposes into elemental mercury and oxygen: 2 HgO(s) → 2 Hg(l) + O2(g) ΔH° = 181.6 kJ ΔS° = 216.4 J/K Estimate the temperature at which HgO should begin to decompose if the partial pressure of O2(g) is constant at 1.00 atm.

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
