化学素质的核心是促进思维的发展,达到思维的优化,这也是新课程标准所倡导的化学教学的基本任务。化学知识与数学方法相结合,可从定量的角度在更高的层次上揭示化学规律,从五彩缤纷的宏观物质世界与绚丽多姿的微观物质的量反映物质的化学特性,由此及彼,由表及里,加深对化学知识的理解和灵活运用。一、不等式法解题过程是一个复杂的思维过程,要求每道题的解题思路都能顺顺当当,直达目标,是不现实的。当思路“卡壳”时,调整解题策略,挖掘和翻新化学信息,创设多元化的思维环境,在中断的解题之路上架起一座通畅的桥梁。如确定混合体系中某组分的量的范 The core of chemistry quality is to promote the development of thinking and achieve the optimization of thinking. This is also the basic task of chemistry teaching advocated by the new curriculum standards. The combination of chemical knowledge and mathematical methods can reveal the laws of chemistry from a quantitative perspective at a higher level, reflecting the chemical properties of matter from the colorful macroscopic material world and the quantity of microscopic substances of various colors. In and out of the table, deepen understanding and flexible use of chemical knowledge. First, the inequality problem solving process is a complicated thinking process. It is unrealistic to require that the problem-solving ideas of each problem be smoothly and directly reach the goal. When the idea of ​​“cracking”, adjust problem solving strategies, excavate and refurbish chemical information, create a diverse environment of thinking, and build a smooth bridge on the road to solving problems. Such as determining the amount of a component in a mixed system
