periodic table\nconsider aqueous solutions of the four compounds: mgcl₂ na₂o c₁₂h₂₂o₁₁ c₂h₅oh\nwhich two…

Explanation:

Step1: Define electrolytes

Electrolytes conduct electricity in solution. Ionic compounds are electrolytes.

Step2: Analyze $MgCl_2$

$MgCl_2$ is an ionic compound. In water, it dissociates into $Mg^{2 + }$ and $2Cl^{-}$ ions which can carry electric charge.

Step3: Analyze $Na_2O$

$Na_2O$ reacts with water to form $NaOH$. $NaOH$ is an ionic compound and dissociates into $Na^{+}$ and $OH^{-}$ ions in water, allowing it to conduct electricity.

Step4: Analyze $C_{12}H_{22}O_{11}$

Sucrose ($C_{12}H_{22}O_{11}$) is a covalent compound. It dissolves in water but does not dissociate into ions, so it cannot conduct electricity.

Step5: Analyze $C_2H_5OH$

Ethanol ($C_2H_5OH$) is a covalent compound. It dissolves in water but does not dissociate into ions, so it cannot conduct electricity.

Answer:

$MgCl_2$ and $Na_2O$
