涉及到化学反应的计算题千变万化,但只要我们抓住化学反应的实质,那么不论怎么复杂的计算都可化繁为简,迎刃而解。特别是终态分析法,在分析清楚化学反应的过程后,只需考虑反应的最终结果,不拘泥于细枝末节,从大处着手,借助守恒思维,往往能出奇制胜,有令人惊叹的效果。例题1 (2 The computational problems involved in chemical reactions are ever-changing, but as long as we grasp the essence of chemical reactions, then no matter how complex calculations can be simplified, they can be easily solved. In particular, the final analysis method, after analyzing the process of chemical reactions clearly, only needs to consider the final result of the reaction, and does not rigidly adhere to the details, start from a big point, and use conservation thinking, they can often surprise and have amazing results.
