What is the simple definition of chemistry?
Chemistry is the branch of science that deals with the properties, composition, and structure of elements and compounds, how they can change, and the energy that is released or absorbed when they change.
What is the correct definition of chromatography?
Chromatography is a process for separating components of a mixture. The different components of the mixture travel through the stationary phase at different speeds, causing them to separate from one another.
