化学方程式是学习化学的基础,是贯穿整个化学学科的线索.化学方程式是描述化学变化的最重要的用语,学好化学方程式是学好化学学科的基石.而对于初中生来说,学习化学方程式既是一个重点,也是一个难点.那么,如何才能学好化学方程式呢?让我们从以下几点说明.一、关注重点,促进学习用化学式来表示化学反应的式子,叫作化学方程式.从“质”的角度分析,化学方程式表示一个化学反应(化学变化)中,什么物质参与了反应,在何种条件下,生成了什么物质;从“量”的角度分析,宏观上看,化学方程式表示了反应过程中,反应物与生成物之间 Chemistry equation is the basis of learning chemistry, is the clue throughout the chemistry .Chemical equation is the most important term to describe chemical changes, learning chemistry equation is the cornerstone of learning chemistry.For junior high school students, learning chemistry equation is not only a Focus, but also a difficult point.Then, how to learn the chemical equation? Let us explain from the following points: First, focus on the focus, to promote the use of chemical formula to express the chemical reaction formula, known as the chemical equation from “From the perspective of chemical equations that a chemical reaction (chemical changes), what substances involved in the reaction, under what conditions, what material is generated; from the” quantitative "point of view, macroscopically, the chemical equation Refers to the reaction between reactants and products
