质量守恒定律作为化学的基本定律之一,是学生认识与理解化学反应的基础。引导学生深刻理解和应用质量守恒定律,有助于学生快速形成宏微结合的思想认识,有助于培养学生的整体思维能力,有助于方便快捷地解决较复杂的计算问题。最能体现化学学科特色和核心内容的观念是微粒观、元素观、转化观、结构观等,因此,对质量守恒定律的理解也应建立在化学观念的基础上。具体来说,基于化
As one of the basic laws of chemistry, the law of conservation of mass is the basis of students’ understanding and understanding of chemical reactions. Guide students to deeply understand and apply the law of conservation of mass, help students to quickly form a macro-micro-ideological understanding, help to develop the overall thinking ability of students, help to quickly and easily solve more complex computational problems. The concepts that best embody the characteristics and core contents of chemistry are the concept of particle, the concept of element, the concept of transformation, and the concept of structure. Therefore, the understanding of the law of conservation of mass should also be based on the concept of chemistry. Specifically, based on
