Can complete or net ionic equations be written for combination or decomposition reactions?

Question

I mean, is it usually done? Or, are these type of equations intended just for single and double displacement reactions?

Answer 1

Complete equations can always be written for these. Net ionic reactions are difficult, because the starting materials are covalent molecules, and the products are also. However, here goes:

Sb + I2 ===>Sb3+ + 3I-
Or is SbI3 a covalent compound
