* Physical Chemists: They focus on the fundamental principles of chemistry, including the rates and mechanisms of chemical reactions. They might study how chemical changes occur at the molecular level.
* Inorganic Chemists: They study the properties and reactions of inorganic compounds, which are compounds that don't typically contain carbon (though there are exceptions). This could include changes involving metals, minerals, and gases.
* Organic Chemists: They specialize in the study of carbon-containing compounds, which make up the vast majority of substances in living things. Organic chemists study how organic molecules react and change, forming new molecules.
* Analytical Chemists: They focus on identifying and quantifying substances. They might analyze the products of a chemical change to determine what new substances have been formed.
* Biochemists: They study chemical processes occurring within living organisms. They might focus on how chemical changes drive metabolism, growth, and other biological functions.
Ultimately, the specific chemist studying a chemical change would depend on the nature of the change itself.
