Question

1. $\text{br}_3\text{o}_2$12. $\text{n}_5\text{cl}_3$13. $\text{p}_6\text{f}_{10}$14. $\text{i}_4\text{s}_7$15. $\text{f}_8\text{o}_5$

Explanation:

These are covalent compounds, named by using prefixes for subscripts (1=mono, 2=di, 3=tri, 4=tetra, 5=penta, 6=hexa, 7=hepta, 8=octa, 10=deca), with the second element ending in "-ide". "Mono-" is omitted for the first element if its subscript is 1.

Answer:

1. Tribromine dioxide
2. Nitrogen trichloride
3. Hexaphosphorus decafluoride
4. Tetraiodine heptasulfide
5. Octafluorine pentoxide
