Chemical inference problem is a very important type of problem in junior high school chemistry. Such problems have the characteristics of hidden conditions, more graphs, complex relationships, and strong comprehensive features. Compared with the previous questions in 2004, inference questions The proposition level is higher, and the flexibility of the questions is also greater. First, solve the problem Step 1. Examine the question carefully read the original question, clarify the meaning of the text and figure, manage the question to the conditions, dig deeper and narrower to find, and repeatedly weigh. Analyze and seize the key, find the breakthrough point for problem solving, and proceed from the breakthrough, explore the internal connection between knowledge, apply a variety of ways of thinking, conduct rigorous analysis and logical reasoning.
