分类是把某些特征相似的物质归类到一起的方法,它是学习和研究化学物质及其变化的一种常用的科学手段.运用分类的方法不仅能使有关化学物质及其变化系统化,还可以通过分门别类的研究,简化一些繁琐复杂的实验操作,加快对物质的认识进程,从而认识物质性质、用途及变化规律.下面笔者就物质分类的有关试题作些分析.
Classification is a method of categorizing certain substances with similar characteristics. It is a common scientific method for learning and studying chemical substances and their changes. Using classification methods can not only systematize relevant chemical substances and their changes. It is also possible to simplify some cumbersome and complicated experimental operations by sorting and classifying, and to speed up the process of understanding the matter, so as to understand the nature of the substance, its use, and the law of change. The following author makes some analysis on the questions related to the classification of matter.
