Explanation:

Step1: Name compound, classify ionic/covalent

Ionic compounds form between metals/nonmetals or polyatomic ions; covalent between nonmetals.

Step2: List each compound's name and class

Go through each formula systematically.

Answer:

1. $\text{P}_4\text{O}_{10}$: Tetraphosphorus decoxide, C
2. $\text{Li}_3\text{P}$: Lithium phosphide, I
3. $\text{KHSO}_4$: Potassium bisulfate, I
4. $\text{FeS}$: Iron(II) sulfide, I
5. $\text{Pb(ClO}_4\text{)}_2$: Lead(II) perchlorate, I
6. $\text{MgBr}_2$: Magnesium bromide, I
7. $\text{ZnSO}_4$: Zinc sulfate, I
8. $\text{K}_2\text{CO}_3$: Potassium carbonate, I
9. $\text{Cl}_2\text{Sn}$ (should be $\text{SnCl}_2$): Tin(II) chloride, I
10. $\text{H}_2\text{O}$: Water, C
11. $\text{Al}_2\text{O}_3$: Aluminum oxide, I
12. $\text{NF}_3$: Nitrogen trifluoride, C
13. $\text{CO}_2$: Carbon dioxide, C
14. $\text{NH}_4\text{NO}_3$: Ammonium nitrate, I
15. $\text{Cu(NO}_3\text{)}_2$: Copper(II) nitrate, I
16. $\text{Ca}_3\text{N}_2$: Calcium nitride, I
17. $\text{AlPO}_4$: Aluminum phosphate, I
18. $\text{Na}_2\text{O}$ (assumed from $\text{Na}_2$): Sodium oxide, I
19. $\text{CCl}_4$: Carbon tetrachloride, C
20. $\text{KCN}$: Potassium cyanide, I
21. $\text{HCl}$: Hydrochloric acid, I
22. $\text{CH}_4$: Methane, C
23. $\text{Ba(OH)}_2$ (assumed from $\text{Ba(OH)}$): Barium hydroxide, I
24. $\text{H}_2\text{S}$: Hydrosulfuric acid, C (weak acid, covalent in pure form)
