化学是一门实验性很强的自然科学,其化学原理和化学规律都是在实验的基础上所得出的。化学实验,是有目的地使自然界中的化学现象在特定的环境下简单化、明晰化,将主要因素重现出来,以便于进行观察研究,认识物质及其变化。化学的概念、规律和原理,大都是从实验出发,在实验观察的基础上经过分析、综合而总
Chemistry is a highly experimental natural science, the chemical principles and chemical laws are based on the experiment derived. Chemical experiments are designed to simplify and clarify chemical phenomena in nature in a specific environment and reproduce the major factors so as to facilitate observation and study and to understand the matter and its changes. The concepts, laws and principles of chemistry are mostly from the experiment, based on the experimental observations after analysis, the total and total
