一般情况下,高考中的化学计算题给的背景都比较简单,所以,出题者不单单是考查学生的专业知识能力,更重要的是考查学生的思维方式。思维方式是解决化学计算题的核心,思维方式一般分为惯性思维和另类思维。因此,学生在审题的过程中若可以发现一些突破口,采用另类思想解题,往往可以达到化繁为简,快速解题的目的。一、反应过程复杂时——整体思想在求解金属和酸反应的相关计算时,经常会出现金属的种类在两种或两种以上的情况,当金
Under normal circumstances, the college entrance examination in the calculation of chemistry to the background is relatively simple, so the question is not only to examine the students’ professional knowledge and ability, more importantly, to examine the way students think. Way of thinking is to solve the core of chemical calculation problem, the way of thinking is generally divided into inertial thinking and alternative thinking. Therefore, if students can find some breakthroughs in the process of examining questions, using alternative thinking to solve problems can often achieve the purpose of simplifying and quick solving problems. First, the reaction process is complex - the overall idea in the calculation of metal and acid reaction related calculations, often occur in two or more kinds of metal in the case of gold
