Explanation:

Step1: Identify ionic compound naming rules

For ionic compounds, name the metal first and then the non - metal with the ending changed to “-ide”.

Step2: Name KBr

Potassium (K) is the metal and bromine (Br) is the non - metal. So the name is potassium bromide.

Step3: Name Ba₃N₂

Barium (Ba) is the metal and nitrogen (N) is the non - metal. The name is barium nitride.

Step4: Name Ca₃N₂

Calcium (Ca) is the metal and nitrogen (N) is the non - metal. The name is calcium nitride.

Step5: Identify covalent compound naming rules

For covalent compounds, use prefixes to indicate the number of atoms of each element.

Step6: Name P₂O₅

The prefix for 2 is “di -” and for 5 is “penta -”. The name is diphosphorus pentoxide.

Step7: Name CO

The prefix for 1 (not used for the first element if it's 1) and for 1 is “mono -”. The name is carbon monoxide.

Step8: Name CCl₄

The prefix for 1 (not used for carbon here) and for 4 is “tetra -”. The name is carbon tetrachloride.

Step9: Name P₃O₆

The prefix for 3 is “tri -” and for 6 is “hexa -”. The name is triphosphorus hexoxide.

Step10: Name SO₂

The prefix for 1 (not used for sulfur) and for 2 is “di -”. The name is sulfur dioxide.

Step11: Name NF₃

The prefix for 1 (not used for nitrogen) and for 3 is “tri -”. The name is nitrogen trifluoride.

Step12: Name S₃O₆

The prefix for 3 is “tri -” and for 6 is “hexa -”. The name is trisulfur hexoxide.

Step13: Write formula for potassium oxide

Potassium has a + 1 charge (K⁺) and oxygen has a - 2 charge (O²⁻). To balance the charges, the formula is K₂O.

Step14: Write formula for magnesium nitride

Magnesium has a + 2 charge (Mg²⁺) and nitrogen has a - 3 charge (N³⁻). The formula is Mg₃N₂.

Step15: Write formula for lithium phosphide

Lithium has a + 1 charge (Li⁺) and phosphorus has a - 3 charge (P³⁻). The formula is Li₃P.

Step16: Write formula for calcium nitride

Calcium has a + 2 charge (Ca²⁺) and nitrogen has a - 3 charge (N³⁻). The formula is Ca₃N₂.

Step17: Write formula for barium sulfide

Barium has a + 2 charge (Ba²⁺) and sulfur has a - 2 charge (S²⁻). The formula is BaS.

Step18: Write formula for dinitrogen tetrachloride

The prefix “di -” means 2 for nitrogen (N) and “tetra -” means 4 for chlorine (Cl). The formula is N₂Cl₄.

Step19: Write formula for silicon dioxide

The prefix “di -” means 2 for oxygen (O) and 1 for silicon (Si, not shown as a prefix when it's 1). The formula is SiO₂.

Step20: Write formula for trisulfur hexoxide

The prefix “tri -” means 3 for sulfur (S) and “hexa -” means 6 for oxygen (O). The formula is S₃O₆.

Step21: Write formula for diphosphorus pentafluoride

The prefix “di -” means 2 for phosphorus (P) and “penta -” means 5 for fluorine (F). The formula is P₂F₅.

Step22: Write formula for carbon tetrachloride

The prefix “tetra -” means 4 for chlorine (Cl) and 1 for carbon (C, not shown as a prefix when it's 1). The formula is CCl₄.
