Which of the following is a decomposition reaction?

2 KClO3 → 2 KCl + 3 O2

Zn + 2 HCl → ZnCl2 + H2

Fe + S → FeS

All of the above are examples of decomposition.

D

Answer 1

You need to do better than this. I can't tell the difference between questions and answers. In fact, I'm not sure of the question. With regard to the last one, the KClO3 is the decomposition. The Zn and HCl is a single replacement and the Fe and S rxn is synthesis.
