化学反应是高中化学核心内容之一,综观近年来高考题,主要考查物质的性质及转化、化学(离子)方程式的书写或正误判断、新情境下陌生方程式的书写。单纯记忆化学反应费时费力,必须理解有关反应的实质和规律,下面我们看看反应中的强弱规律。 Chemistry is one of the core contents of chemistry in senior high schools. Taking a comprehensive review of the entrance examinations in recent years, we mainly examine the nature of matter, the writing of chemical (ion) equations, and the judgment of unfamiliar equations in new situations. Pure memory chemical reaction takes time and effort, we must understand the nature of the reaction and the law, the following we look at the reaction law of strength.
