Chemistry is the branch of science that deals with the properties, structure, and composition of elements and compounds, how they can change, and the energy released or absorbed when they change.
The Scope of Chemistry
Chemistry is the study of matter and the ways in which different forms of matter combine with each other. You study chemistry because it helps you understand the world around you. Everything you touch or taste or smell is a chemical, and the interaction of these chemicals with each other defines our universe. Chemistry is the foundation of biology and medicine. From the structure of proteins and nucleic acids to the design, synthesis and manufacture of drugs, chemistry allows you to.
Hypothesis, Theories, and Laws
Although all of us have taken science classes throughout the course of our study, many people have incorrect or misleading ideas about some of the most important and basic principles in science. We have all heard of hypotheses, theories, and laws, but what do they really mean? Before you read this section, think about what you have learned about these terms before. What do these terms mean to you? What do you read contradicts what you thought? What do you read supports what you thought?
A Beginning Chemist – How to Succeed
Most people can succeed in chemistry, but it often requires dedication, hard work, the right attitude and study habits!
Physical and chemical changes
A physical change is a change in a sample of matter in which some of the properties of the substance change, but the identity of the substance is not. In contrast, a chemical property describes the ability of a substance to undergo a specific chemical change.
