论文部分内容阅读
在中学化学里,无机物的化学反应按本质可分为两类,一类为物质在反应中没有获得和失去电子的,叫做非氧化——还原反应;一类为物质在反应中有获得和失去电子的,叫做氧化——还原反应,后者占多数。中学生在学完无机化学部分,或在高考前的总复习中,对氧化——还原反应感到有下列问题。 1、发生反应的可能性和反应产物是什么,怎样分析和推断;
In middle school chemistry, the chemical reaction of inorganic substances can be divided into two categories by the essence. One is that the substance does not acquire and lose electrons in the reaction, which is called non-oxidation-reduction reaction; the other is that the substances are obtained in the reaction and Loss of electrons is called oxidation-reduction, which accounts for the majority. After studying the inorganic chemistry part or the general review before the college entrance examination, middle school students have the following problems with the oxidation-reduction reaction. 1, the possibility of reaction and what is the reaction product, how to analyze and infer;
