which of the following compounds are ionic? check all that apply. sf₂ h₂o mgo sih₄ co₂ none of the above

Answer

Explanation:

Step1: Recall ionic compound rule

Ionic compounds are usually formed between a metal and a non - metal.

Step2: Analyze each compound

$SF_2$: Sulfur and fluorine are non - metals, so it's covalent.
$H_2O$: Hydrogen and oxygen are non - metals, so it's covalent.
$MgO$: Magnesium (a metal) and oxygen (a non - metal), so it's ionic.
$SiH_4$: Silicon and hydrogen are non - metals, so it's covalent.
$CO_2$: Carbon and oxygen are non - metals, so it's covalent.

Answer:

MgO
