氮族元素是元素化合物知识构成的重要内容,也是高考考查的热点,其有关计算一直为命题者所“青睐”。下面就含氮化合物的常见计算类型归类分析如下,供参考。一、氮的氧化物的有关计算此类问题主要有以下几种设题形式:一是NO_x与水或NO_x和O_2的混合气体与水反应计算,二是NO_x和CO_2的混合气体与Na_2O_2反应计算,三是NO_x与NaOH溶液反应的有关计算,四是NO_x的氧化还原反应计算等。解法指要:处理这类问题时,一是运用关系式法
The nitrogen group element is an important content of the knowledge of the elemental compound, and is also a hot spot of the college entrance examination. Its calculation has always been the favor of the proposition. The following classification analysis of common calculation types of nitrogen-containing compounds is provided below for reference. 1. Calculation of Nitrogen Oxides This type of problem mainly includes the following types of questions: one is the calculation of the reaction between NO_x and water or NO_x and O_2 mixed gas and water, and the second is the calculation of the reaction between NO_x and CO_2 mixed gas and Na_2O_2. The third is the calculation of the reaction between NO_x and NaOH solution, and the fourth is the calculation of NO_x redox reaction. The solution refers to: When dealing with such issues, one is to use the relational method.
