Answer

Explanation:

Step1: Analyze first equation

The reaction $2HgO(s)\rightarrow2Hg(l)+O_2(g)$ has mercury in liquid - state ($Hg(l)$) and oxygen in gaseous - state ($O_2(g)$) as products.

Step2: Analyze second equation

The reaction $2Mg(s)+O_2(g)\rightarrow2MgO(s)$ has only solid magnesium oxide ($MgO(s)$) as a product.

Step3: Analyze third equation

The reaction $2KClO_3(s)\rightarrow2KCl(s)+3O_2(g)$ has solid potassium chloride ($KCl(s)$) and gaseous oxygen ($O_2(g)$) as products, but no liquid product.

Step4: Analyze fourth equation

The reaction $Mg(s)+2HCl(aq)\rightarrow H_2(g)+MgCl_2(aq)$ has gaseous hydrogen ($H_2(g)$) and an aqueous solution of magnesium chloride ($MgCl_2(aq)$), but no liquid product in the pure sense.

Answer:

$2HgO(s)\rightarrow2Hg(l)+O_2(g)$
