Final answer:
The chemical formulas for the ionic compounds are written by balancing the charges of the metal cations and the non-metal anions: Pb3N2 for lead(II) nitride, Co2S3 for cobalt(III) sulfide, MnO2 for manganese(IV) oxide, CrI3 for chromium(III) iodide, Li3N for lithium nitride, and Au2O for gold(I) oxide.
Step-by-step explanation:
The formulas for the given ionic compounds are as follows:
- a. Lead(II) nitride - Pb3N2
- b. Cobalt(III) sulfide - Co2S3
- c. Manganese(IV) oxide - MnO2
- d. Chromium(III) iodide - CrI3
- e. Lithium nitride - Li3N
- f. Gold(I) oxide - Au2O
Each compound is written by balancing the charges between the metal cations and non-metal anions.
