Final Answer:
1. CO — carbon monoxide
2. CO₂ — carbon dioxide
3. H₂O — water
4. NH₃ — ammonia
5. CH₄ — methane
6. NO — nitric oxide
7. N₂O — dinitrogen monoxide
8. N₂O₅ — dinitrogen pentoxide
9. N₂O₄ — dinitrogen tetroxide
10. PCl₃ — phosphorus trichloride
11. PF₅ — phosphorus pentafluoride
12. F₂O — difluoro oxide (or oxygen difluoride)
13. SO₂ — sulfur dioxide
14. S₂O₃ — disulfur trioxide
15. SiCl₄ — silicon tetrachloride
16. BCl₃ — boron trichloride
17. BN — boron nitride
18. CS₂ — carbon disulfide
19. SeF₆ — selenium hexafluoride
20. H₂O₂ — hydrogen peroxide
21. Cl₂O — dichlorine monoxide
22. N₂O — dinitrogen monoxide *(already listed as #7; likely duplicate)*
23. NI₃ — nitrogen triiodide
24. AsCl₃ — arsenic trichloride
25. CCl₄ — carbon tetrachloride
26. SeF₆ — selenium hexafluoride *(duplicate of #19)*
27. SiO₂ — silicon dioxide
28. H₂S — hydrogen sulfide
29. SF₆ — sulfur hexafluoride
30. SO₃ — sulfur trioxide

32. Cl₂O₇ — dichlorine heptoxide
33. BBr₃ — boron tribromide
34. XeF₂ — xenon difluoride
35. SCl₂ — sulfur monochloride *(actually disulfur dichloride is S₂Cl₂; SCl₂ is sulfur dichloride)*
36. N₃ — not a stable compound; likely typo — possibly N₂ (nitrogen gas) or NaN₃ (sodium azide), but as written, invalid
37. Cl₂ — chlorine gas
38. BrF₅ — bromine pentafluoride
39. SiCl₄ — silicon tetrachloride *(duplicate of #15)*
40. ICl — iodine monochloride
