化学平衡是重要的化学基础理论之一,也是化学教学中的一个难点。教学中教师应该遵循由浅入深、循序渐进的教学规律,采取具体的事例进行分析、绘制图表加以辅助、适当比喻进一步说明等方法,使问题化繁为简、化难为易,便可取得较佳的课堂效果。化学平稳是针对可逆反应而言的,而可 Chemical balance is one of the important basic chemical theories, and it is also a difficult point in chemistry teaching. In teaching, teachers should follow a shallow, deep and gradual teaching law, adopt concrete examples to analyze, draw diagrams to assist, and appropriate metaphors for further explanation, etc., so as to simplify problems and make it easier to achieve better results. Classroom effect. Chemical stability is for reversible reactions, but
