Question

If you're good with covalent bonds please help.

Answer 1

`SiS_2`: Silicon disulfide

`NBr_3`: Nitrogen tribromide

`N_2Cl_4`: Dinitrogen tetrachloride

Step-by-step explanation:

Whenever you have an binary compound such as this, you can look at the individual elements for the name. The first word will simply be the prefix + the name of the element.

*** Notice you don't need to put a prefix if theres only 1. This is understood as mono. Only on the first word.

For the second word, its simply the root + ide.
