Impurities in water are from dissolved rocks an minerals, river deposits, absorbed gases, degraded materials fron living beings.
The chemical composition remain unchanged.
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.

Yes, the composition of the rocks is as a result of the distinct chemical composition.
Substances in solution in the oceans originate from a variety of sources, including weathering of rocks on land, volcanic activity, atmospheric deposition, and biological processes. These sources contribute elements and compounds that dissolve in seawater, creating the complex chemical composition of the oceans.
The chemical composition of water remain unchanged.
They 'imprint' the chemical composition of the stretch of water where they hatch. Once they reach adulthood (after swimming in the oceans) they use this imprinted knowledge to 'home in' on the river where they hatched.
A chemical change involve a change of composition.
A liquid is a compound or a mixture; the chemical composition is representative for this liquid.
What is the chemical composition of kf reagent
Several chemical properties can be estimated knowing the chemical composition.
