在中学化学教材中,有一种特别活泼的重要的金属元素及其化合物,那就是钠及过氧化钠(Na_2O_2),在高考考查中时有出现且考生较易出错,现针对“Na_2O_2”知识点结合实例做一探究,供大家学习参考。一、明确各种物质间相互转化关系图,熟识Na_2O_2的结构特点及其相关性质在复习过程中,我们首先要明确该元素所对应的各种物质之间的相互转化关系,在我们自己的心目中留下一个清晰的脉络,其次,我们要会书写相关的化学反应方程式,知
In the middle school chemistry textbook, there is a particularly active and important metal elements and their compounds, that is, sodium and sodium peroxide (Na 2 O 2), in the college entrance examination sometimes appear and the candidates more error-prone, for “Na_2O_2” Knowledge points to do with an example to explore, for your reference. First, a clear relationship between the conversion of various substances diagram, familiar with the structural characteristics of Na_2O_2 and its related properties In the review process, we must first clear that the element corresponding to the mutual transformation between the various substances in our own minds Leaving a clear context, and secondly, we will write about the chemical reaction equation, that
