Answer:
The chemical equation for the decomposition of mercury(II) oxide is:
2HgO(s) → 2Hg(l) + O2(g)
This means that when solid mercury(II) oxide (HgO) is heated, it breaks down into liquid mercury (Hg) and gaseous oxygen (O2). The reaction is a decomposition reaction because one reactant (HgO) is broken down into two products (Hg and O2). This reaction is also exothermic, meaning that it releases heat.
