Writing chemical formulas from compound names is an essential skill in chemistry that bridges understanding between chemical nomenclature and molecular composition. It requires knowledge of chemical symbols, valency, and the rules governing chemical formulas, including the use of parentheses, subscripts, and charge balancing. This paper explores the methodology for translating compound names into their correct chemical formulas, exemplifying this process with a series of compounds provided in the prompt.

First, let's examine the general approach to formula writing. The key steps include identifying the cation and anion, understanding their charges, and balancing these charges to form an electrically neutral compound. When dealing with polyatomic ions, proper recognition of their formulas and charges is vital, as are conventions for using parentheses to indicate multiple polyatomic groups.

Let us now analyze each compound from the list and determine its chemical formula, explaining the process in detail for each.

1. Ammonium Phosphate

The ammonium ion, NH₄⁺, and the phosphate ion, PO₄³⁻, are polyatomic ions. To balance charges, multiply NH₄⁺ by 3 to get a total positive charge of +3, and PO₄³⁻ has a charge of -3. These charges cancel each other naturally, resulting in the formula (NH₄)₃PO₄.

2. Magnesium Hydroxide

Magnesium, Mg²⁺, and hydroxide, OH⁻, combine in a 1:2 ratio to balance charge (+2 and -2). The formula is Mg(OH)₂.

3. Potassium Permanganate

Potassium ion, K⁺, and permanganate ion, MnO₄⁻. To balance charge, combine one K⁺ with MnO₄⁻, resulting in KMnO₄.

4. Iron (II) Oxide

Iron (Fe²⁺) and oxide, O²⁻. Both charges are 2, so one Fe²⁺ pairs with one O²⁻, giving FeO.

5. Aluminum Sulfate

Aluminum, Al³⁺, and sulfate, SO₄²⁻. To balance, multiply Al³⁺ by 2 and sulfate by 3, resulting in Al₂(SO₄)₃.

6. Sodium Hydrogen Carbonate

Also known as baking soda, NaHCO₃, includes sodium ion, Na⁺, hydrogen carbonate (bicarbonate), HCO₃⁻. The formula indicates one sodium ion with one bicarbonate group.

7. Carbon Monoxide

Carbon and oxygen in a 1:1 ratio, with the formula CO.

8. Copper (II) Sulfate

Copper (II), Cu²⁺, and sulfate, SO₄²⁻. Charges balance directly, giving CuSO₄.

9. Zinc Nitrate

Zinc, Zn²⁺, and nitrate, NO₃⁻. Two nitrates per zinc ion, resulting in Zn(NO₃)₂.

10. Calcium Chloride

Calcium, Ca²⁺, and chloride, Cl⁻. Two chlorides per calcium, formula CaCl₂.

11. Lead (IV) Chromate

Lead (IV), Pb⁴⁺, and chromate, CrO₄²⁻. To balance, multiply CrO₄²⁻ by 2 and Pb by 1. With a charge of +4 for lead and -2 for chromate, two chromate ions balance one lead ion, resulting in Pb(CrO₄)₂.

12. Aluminum Sulfite

Aluminum, Al³⁺, and sulfite, SO₃²⁻. To balance, the least common multiple gives 2 Al³⁺ (total +6) and 3 sulfite (total -6), formula Al₂(SO₃)₃.

13. Potassium Nitrate

Potassium, K⁺, and nitrate, NO₃⁻, with a 1:1 ratio forming KNO₃.

14. Diphosphorus Pentoxide

Meta-molecular formula P₂O₅, indicating two phosphorus atoms and five oxygen atoms.

15. Iron (III) Oxide

Iron (III), Fe³⁺, and oxide, O²⁻. To balance, combine two Fe³⁺ (total +6) with three O²⁻ (total -6), forming Fe₂O₃.

In conclusion, the process of converting chemical names into formulas involves careful analysis of the ions involved, their charges, and the application of chemical nomenclature rules. Mastery of this skill facilitates a deeper understanding of chemical composition and behavior, essential for advanced study and scientific communication in chemistry heavily relies on accurate formula writing. Building proficiency in these techniques enables students and chemists to interpret, construct, and communicate chemical information effectively across various contexts and applications.
