Answer

Explanation:

Step1: Analyze first equation

The products of $2HgO(s)\rightarrow2Hg(l) + O_2(g)$ are liquid mercury ($Hg(l)$) and oxygen gas ($O_2(g)$).

Step2: Analyze second equation

The product of $2Mg(s)+O_2(g)\rightarrow2MgO(s)$ is solid magnesium - oxide ($MgO(s)$), no liquid or gas as required.

Step3: Analyze third equation

The products of $2KClO_3(s)\rightarrow2KCl(s)+3O_2(g)$ are solid potassium chloride ($KCl(s)$) and oxygen gas ($O_2(g)$), no liquid.

Step4: Analyze fourth equation

The products of $Mg(s)+2HCl(aq)\rightarrow H_2(g)+MgCl_2(aq)$ are hydrogen gas ($H_2(g)$) and aqueous magnesium chloride ($MgCl_2(aq)$), no liquid in pure form.

Answer:

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