We use chemicals every day and perform chemical reactions without thinking much about them. Chemistry is important because everything you do is chemistry. Even your body is made of chemicals. All matter is made of chemicals, so the importance of chemistry is that it's the study of everything. Chemistry covers so many specialties, sub-specialties, subjects, topics and knowledge areas. Important ones of these are: organic chemistry, atomic structure & theory, chemical bonding, hydrocarbons, moles and equations and the chemistry of life. For this test, domain experts at Examinations Hub have chosen questions in 3 difficulty levels (easy, medium and difficult) from A-level chemistry . Please note that the figures of “Number Of Questions In Actual Exam” & “Passing Percentage” are random figures with no significance in the context of this test.
