镁与氮气反应生成氮化镁是镁重要的化学性质之一,然而中学化学教材中并没有该反应的演示实验,学生在学习过程中只能机械地记忆相关内容,缺乏直接的感性认识。部分化学教学工作者敏锐地发现了这一问题,设计出了一些解决方案。笔者以“镁与氮气反应”为主题在中国知网CNKI学术期刊全文数库中进行检索,共找到3篇相关文章,但这些文章的设计方案均存在诸 The reaction between magnesium and nitrogen to form magnesium nitride is one of the important chemical properties of magnesium. However, there is no demonstration experiment of this reaction in the middle school chemistry textbooks. Students can only memorize relevant contents mechanically during the learning process, and lack of direct perceptual knowledge. Some chemistry teaching workers keenly discovered this problem and devised some solutions. The author searches for “Magnesium and Nitrogen Reaction” in CNKI academic periodical full-text database, and found 3 related articles, but the design of these articles are all different
