The task involves classifying chemical compounds into specific categories—ionic compounds, molecular compounds, oxyacids, and binary acids—and subsequently naming them accordingly. Additionally, it requires formulating chemical formulas based on given compound names. Understanding these classifications and nomenclature rules is fundamental in chemistry, as it allows for effective communication of chemical compositions and properties.

Classification and Naming of Compounds

Compounds are broadly categorized based on their constituent ions and bonds. Ionic compounds comprise positively charged ions (cations) and negatively charged ions (anions), typically formed between metals and nonmetals. Molecular compounds consist of nonmetals bonded covalently. Oxyacids contain hydrogen, oxygen, and another element, usually a nonmetal, often characterized by specific naming conventions. Binary acids are composed of hydrogen and a halogen or other nonmetal, and their names typically start with “hydro-” followed by the root of the nonmetal and “-ic” for acid forms.

Part 1: Classification and Naming of Compounds

1. BaCl2 — This is an ionic compound composed of the barium cation (Ba²⁺) and chloride anions (Cl^-). It is named barium chloride.

2. FeCl3 — An ionic compound consisting of iron (Fe³⁺) and chloride (Cl^-) ions. Named iron(III) chloride, indicating the Fe oxidation state.

3. SO2 — A molecular compound formed from sulfur and oxygen. It is sulfur dioxide.

4. MgSO4 — An ionic compound of magnesium and sulfate ions, named magnesium sulfate.

5. NaOH — An ionic compound of sodium and hydroxide ions, known as sodium hydroxide.

6. NH4Cl — Ionic compound of ammonium and chloride ions, called ammonium chloride.

7. SF6 — A molecular compound with sulfur and fluorine atoms, sulfur hexafluoride.

8. HBr — A binary acid composed of hydrogen and bromine, hydrobromic acid.

9. H2SO3 — An oxyacid of sulfur with hydrogen and oxygen, called sulfurous acid.

10. I2O5 — A molecular compound of iodine and oxygen, iodine pentoxide.

11. N4Se4 — A molecular compound of nitrogen and selenium, tetranitrogen tetraselenide.

12. HNO2 — An oxyacid with hydrogen, nitrogen, and oxygen, nitrous acid.

13. SrI2 — Ionic compound of strontium and iodide, strontium iodide.

14. Fe2O3 — Ionic compound of iron and oxygen, iron(III) oxide.

15. HNO3 — An oxyacid of nitrogen and oxygen, nitric acid.

Part 2: Writing Formulas of Named Compounds

1. xenon hexafluoride — XeF6

2. lithium nitrite — LiNO2

3. sodium sulfate — Na2SO4

4. copper (I) nitrate — CuNO3 (or CuNO3, indicating copper has a +1 charge)

5. sulfuric acid — H2SO4

Conclusion

Understanding the classification and proper nomenclature of chemical compounds is essential for clear scientific communication. Recognizing the differences between ionic, molecular, oxyacids, and binary acids enables chemists to describe substances precisely, predict their properties, and understand their roles in chemical reactions. Formulating correct chemical formulas based on compound names further aids in experimental design, data recording, and interpretation within the field of chemistry.
