which equation has both a liquid and a gas as products?\n 2hgo(s) → 2hg(l) + o₂(g)\n 2mg(s) + o₂(g) → 2mgo(s)\n 2kclo₃(s) → 2kcl(s) + 3o₂(g)\n mg(s) + 2hcl(aq) → h₂(g) + mgcl₂(aq)

Answer

Explanation:

Step1: Analyze each reaction's products' states

  • For ( 2\text{HgO}(s) \rightarrow 2\text{Hg}(l) + \text{O}_2(g) ): Products are liquid (Hg) and gas (O₂).
  • For ( 2\text{Mg}(s) + \text{O}_2(g) \rightarrow 2\text{MgO}(s) ): Product is solid (MgO).
  • For ( 2\text{KClO}_3(s) \rightarrow 2\text{KCl}(s) + 3\text{O}_2(g) ): Products are solid (KCl) and gas (O₂).
  • For ( \text{Mg}(s) + 2\text{HCl}(aq) \rightarrow \text{H}_2(g) + \text{MgCl}_2(aq) ): Products are gas (H₂) and aqueous (MgCl₂).

Step2: Identify the reaction with liquid and gas products

From the analysis, the reaction ( 2\text{HgO}(s) \rightarrow 2\text{Hg}(l) + \text{O}_2(g) ) has a liquid (Hg) and a gas (O₂) as products.

Answer:

( 2\text{HgO}(s) \rightarrow 2\text{Hg}(l) + \text{O}_2(g) ) (the first option)
