Answer
Explanation:
Step1: Recall ionic and covalent compound rules
Ionic compounds usually form between metals and non - metals, while covalent compounds form between non - metals.
Step2: Analyze each compound
- $\text{AgNO}_3$: Silver (metal) and nitrate (non - metal group), ionic, silver nitrate.
- $\text{CuCl}_2$: Copper (metal) and chlorine (non - metal), ionic, copper(II) chloride.
- $\text{CaCl}_2$: Calcium (metal) and chlorine (non - metal), ionic, calcium chloride.
- $\text{CaO}$: Calcium (metal) and oxygen (non - metal), ionic, calcium oxide.
- $\text{CO}_2$: Carbon and oxygen (both non - metals), covalent, carbon dioxide.
- $\text{SF}_6$: Sulfur and fluorine (both non - metals), covalent, sulfur hexafluoride.
- $\text{Na}_2\text{S}$: Sodium (metal) and sulfur (non - metal), ionic, sodium sulfide.
- $\text{Fe}_2\text{O}_3$: Iron (metal) and oxygen (non - metal), ionic, iron(III) oxide.
- $\text{O}_2\text{F}_6$: Oxygen and fluorine (both non - metals), covalent, dioxygen hexafluoride.
- $\text{CS}_2$: Carbon and sulfur (both non - metals), covalent, carbon disulfide.
- $\text{CaS}$: Calcium (metal) and sulfur (non - metal), ionic, calcium sulfide.
- $\text{CuS}$: Copper (metal) and sulfur (non - metal), ionic, copper(II) sulfide.
- $\text{CuSO}_4$: Copper (metal) and sulfate (non - metal group), ionic, copper(II) sulfate.
- $\text{Na}_2\text{SO}_4$: Sodium (metal) and sulfate (non - metal group), ionic, sodium sulfate.
- Iron (II) chloride: $\text{FeCl}_2$, ionic.
- Dinitrogen pentoxide: $\text{N}_2\text{O}_5$, covalent.
- Chlorine monofluoride: $\text{ClF}$, covalent.
- Selenium hexabromide: $\text{SeBr}_6$, covalent.
- Mercury (I) sulfate: $\text{Hg}_2\text{SO}_4$, ionic.
- Sodium oxide: $\text{Na}_2\text{O}$, ionic.
- Tin (IV) oxide: $\text{SnO}_2$, ionic.
- Iron (III) nitrate: $\text{Fe(NO}_3)_3$, ionic.
- Manganese (IV) sulfate: $\text{Mn(SO}_4)_2$, ionic.
