This is the analytical chemistry.
Chemistry is the study of matter, its properties, and how it interacts with other substances. It involves understanding the composition, structure, and behavior of atoms and molecules. Chemistry is used in various fields such as medicine, agriculture, materials science, and environmental science, to name a few.
This is a solid.
Organic chemistry focuses on carbon-based molecular chemistry. Inorganic is everything else. Since organic molecules form the basis for life on our planet, their chemistry is of particular interest and many principles developed in organic chemistry may still be applied to inorganic chemistry.
You think probable to a chemical compound. But today the theory of the fixed composition is not generally valid.
A physical change is a change in the form of matter but not the chemical composition of it.
Changes of the matter that do not change the composition of the substance.
These are physical changes.
Chemistry is the scientific study of the composition of substances and their properties. It also deals with the ways in which these substances interact, combine, and change to form new substances.
Matter ( in any form) with a definite chemical composition . Also a umbrella term for drugs( substance abuse)
chemical reactions can go into many ways, such as bonding.It changes appearances or affect on other things, but chemical reaction generaly means :A change in which a substance (or substances) is changed into one or more new substances.

Inorganic chemistry is the study of chemical compounds without carbon in the molecue (but by tradition several carbon containing compounds are included in the inorganic chemistry).
