Decomposition of a compound is a chemical process.
A mixture is a solution of a compound or the liquid state of a compound. When you make a solution of a salt, the salt will solute in the solvent, and go to the ionic state. Example, NaCl in water: NaCl(s) -> Na+(aq) + Cl-(aq)
Physical change occurs when sulfur and sodium chloride are separated. This is because their chemical compositions remain the same, but their physical states are altered when they are no longer combined.

Condensation represents a physical change as it involves the phase transition of a gas to a liquid. This change occurs when the temperature of the gas decreases, causing the gas molecules to slow down and come closer together, forming a liquid.
Iodine is not a compound. It is an element. Therefore, it has its own atoms: Iodine atoms.
This is a chemical process.
A chemical change occurs because compound is two elements put together so when they are separated it forms a new substance.
