化学方程式与代数方程式有以下七方面之不同：（1）化学方程式的建立必须以客观事实为依据，不能假设，不能随便臆造事实上不存在的化学方程式；而代数方程式可以假设。（2）化学方程式的左、右两边不能调换，左边必须写反应物的化学式，右边必须写生成物的化学式；而代数方程
Chemical equations and algebraic equations are different in the following seven aspects: (1) The establishment of chemical equations must be based on objective facts. It cannot be assumed that chemical equations that do not exist in reality cannot be easily created; algebraic equations can be assumed. (2) The left and right sides of the chemical equation cannot be reversed. The chemical formula of the reactants must be written on the left, and the chemical formula of the product must be written on the left; algebraic equations
