化学是一门自然学科,它研究了物质的结构、组成、性质、变化及其规律。在它的研究和发展史上,许多科学家作出了巨大的贡献。在不断的研究过程中,人们不断地总结经验,使化学逐渐成为一门独立的学科,其中方程式的书写是化学教学中的重点,也是难点,因此,如何正确书写化学方程式是非常重要的。 Chemistry is a natural discipline that studies the structure, composition, nature, changes, and laws of matter. In its history of research and development, many scientists made a great contribution. In the process of continuous research, people constantly sum up experience, chemistry has gradually become an independent discipline, of which the equation writing is the focus of chemistry teaching, but also difficult, therefore, how to correctly write the chemical equation is very important.
