The empirical formula of metal iodide : CoI₃(Cobalt(III) Iodide)
<h3>Further explanation</h3>
13.02 g sample of Cobalt , then mol Co(MW=58.933 g/mol) :
![\tt mol=\dfrac{mass}{Ar}=\\\\mol=\dfrac{13.02~g}{58.933}\\\\mol=0.221](https://tex.z-dn.net/?f=%5Ctt%20mol%3D%5Cdfrac%7Bmass%7D%7BAr%7D%3D%5C%5C%5C%5Cmol%3D%5Cdfrac%7B13.02~g%7D%7B58.933%7D%5C%5C%5C%5Cmol%3D0.221)
Mass of metal iodide formed : 97.12 g, so mass of Iodine :
![\tt =mass~metal~iodide-mass~Cobalt\\\\=97.12-13.02\\\\=84.1~g](https://tex.z-dn.net/?f=%5Ctt%20%3Dmass~metal~iodide-mass~Cobalt%5C%5C%5C%5C%3D97.12-13.02%5C%5C%5C%5C%3D84.1~g)
Then mol iodine (MW=126.9045 g/mol) :
![\tt \dfrac{84.1}{126.9045}=0.663](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7B84.1%7D%7B126.9045%7D%3D0.663)
mol ratio of Cobalt and Iodine in the compound :
Answer:
It is not true that this is an example of a chemical reaction. This is a typical example of physical reaction.
Most physical changes are often phase changes.
A phase change is a change in the physical state of a body.
In this change, it is from solid to liquid.
Now new substances are formed.
When substances are changed from one form to another, it is a physical change.
In a chemical change, a new substance is formed at the end of the process.

Explanation:
Answer:
Limited
Explanation:
For competition to exist within a population or between population, shared or common resources that organisms holds very important must be very limited and scared.
Competition is a struggle between organisms for limited resources in the ecosystem.
- It is an interaction between organisms in which one of them is harmed.
- Competition originates from limited supply of shared or mutual resources among organisms.
- When competition is between organisms from different population, it is called an interspecific competition.
- Competition between organisms within the same population, i.e of the same species is intraspecific competition.
