Answer:
1) S2N
2)ClI
Explanation:
A chemical formula shows the relative ratio of atoms present in a compound. When we write a chemical formula, we have an idea of the ratio in which atoms combine in the compound of interest. This is a great clue when we are attempting to elucidate the structure of the compound.
For hexasulphur mononitride,the formula of the compound must be S6N3, this reduced to lowest terms to give S2N.
Similarly, the formula for chlorine monoiodide is ClI as shown in the answer above.
