Solid HgO, liquid Hg, and gaseous O2 are placed in a glass bulb and are allowed to reach equilibrium at a given temperature. 2HgO(s)+heat2Hg(l)+O2(g) The amount of Hg(l) in the bulb could be increased by 1. removing some HgO 2. removing some O2 3. increasing the temperature A) 1 only B) 2 only C) 3 only D) 1 and 2 only E) 2 and 3 only
