Cl2与FeBr2反应方程式书写是中学生学化学的一大难点,也是一个重点,它涉及到卤素的性质,还涉及到Fe元素的性质,是氧化还原反应的典型题型．我们认为应从下列几点分析、处理:
The writing of the equation of reaction between Cl2 and FeBr2 is a major difficulty in middle school students’ chemistry, and it is also a key point. It involves the nature of halogens, and also relates to the nature of Fe elements. It is a typical problem of redox reactions. We believe that the following points should be analyzed and dealt with:
