世界是由物质构成的,自然科学中的化学学科就是专门研究物质的,研究物质的组成、结构、性质及其变化规律.化学的研究起源于人类的生产活动,十九世纪以后取得了一系列重要进展,提出了原子分子学说、分子结构学说、元素周期律、化学热力学和化学动力学等理论,奠定了现代化学的理论基础.现代化学根据所研究的物质的对象与方法的不同,又有了无机化学、有机化学、分析化学和物理化学等基础分支学科.
The world is made up of matter. The science of chemistry in the natural sciences is devoted to the study of matter and studies the composition, structure, properties, and laws of change. The study of chemistry originated in human activities of production. Important advances, the theory of atomic and molecular theory, theory of molecular structure, periodicity of elements, chemical thermodynamics, and chemical kinetics have been put forward, which laid the theoretical foundation of modern chemistry. Modern chemistry differs according to the objects and methods of substances studied. Inorganic chemistry, organic chemistry, analytical chemistry and physical chemistry and other basic branches.
