Before you go ahead and download the multiple-choice questions, allow me to give you a quick overview of the topic of chemistry.
Chemistry is the branch of science that investigates the formation, behaviour, and changes that take place as a result of the interaction of various atoms, molecules, and ions that make up elements and compounds with other types of substances. In the hierarchy of scientific subfields, chemistry occupies the middle ground between physics and biology in terms of its scope.
