Chemistry is a course that studies the composition, structure, properties, and changes of matter. It explores how substances interact, combine, and react through topics such as organic chemistry, inorganic chemistry, physical chemistry, analytical chemistry, and biochemistry. Students learn to understand chemical reactions, develop laboratory skills, and apply chemical principles in real-world contexts like medicine, energy, agriculture, and industry. The course builds strong problem-solving and analytical abilities. Graduates can work in pharmaceuticals, research, environmental science, food science, petrochemicals, education, or quality control laboratories.
