Question

Which formulas represent one ionic compound and one molecular compound? a. N2 and SO2 b. Cl2 and H2S c. BaCl2 and N2O4 d. NaOH and BaSO4

Answer 1

The formulas that represent one ionic compound and one molecular compound are N2 and NaOH, Cl2 and H2S, BaCl2 and N2O4, and NaOH and BaSO4.

Step-by-step explanation:

The formulas that represent one ionic compound and one molecular compound are:

1. N2 (molecular compound) and NaOH (ionic compound)
2. Cl2 (molecular compound) and H2S (molecular compound)
3. BaCl2 (ionic compound) and N2O4 (molecular compound)
4. NaOH (ionic compound) and BaSO4 (ionic compound)

Answer 2

The formulas that represent one ionic compound and one molecular compound are BaCl₂ (ionic) and N₂O₄ (molecular), making the correct answer option (c).

Step-by-step explanation:

The question asks which formulas represent one ionic compound and one molecular compound. An ionic compound is composed of ions and held together by ionic bonds, typically found between metals and non-metals. A molecular compound is usually composed of nonmetals and held together by covalent bonds.

To identify the correct answer:

• N₂ and SO₂ are both molecular compounds.
• Cl₂ and H₂S are both molecular compounds.
• BaCl₂ is an ionic compound (barium and chlorine) and N₂O₄ is a molecular compound, making answer (c) the correct choice.
• NaOH is an ionic compound (sodium hydroxide) and BaSO₄ (barium sulfate) is also an ionic compound.

Therefore, the formulas that represent one ionic compound and one molecular compound are BaCl₂ and N₂O₄.
