When heatedmercury(II) oxide reacts to mercury and oxygen?

When heated, mercury(II) oxide decomposes into mercury and oxygen gas. This is a chemical reaction where mercury(II) oxide undergoes thermal decomposition. The balanced chemical equation for this reaction is: 2HgO(s) → 2Hg(l) + O2(g)


What is the balanced chemical equation for mercury two chloride plus potassium sulfide?

Potassium is in group one, so according to solubility rules, it will aways be soluble and therefore a spectator ion. That means that it will not take part in the chemical reaction and in a net equation it would not have to be included. HgCl2 + K2S yields HgS + 2KCl(aquious)
