化学方程式在求解化学计算题时应用广泛,合理利用化学方程式可以直接建立已知量与待求量之间的关系,从而省去中间较为繁复的求解步骤,简化思路,便于求解,其中关系式法、差量法、守恒法是根据化学方程式计算问题的几种较为常用的方法。一、明晰反应,巧寻关系关系式法是依据化学方程式求解问题的一种重要的方法,在使用过程中需要利用化学方程式准确分析物质间的质量关系,列出比例式来求解未知量。该方法使用的关键是明晰已知量与未知
The chemical equation is widely used in the calculation of chemical calculation problems, and the rational use of chemical equations can directly establish the relationship between the known amount and the amount to be sought, thus eliminating the need for more complicated solving steps in the middle, simplifying the thinking and facilitating the solution. The relational method Difference method, conservation method is based on chemical equations to calculate the problem of several more commonly used methods. First, the clear response, ingenious relationship relationship law is based on chemical equations to solve the problem of an important method, the use of chemical equations need to use the accurate analysis of the quality of the relationship between substances listed in the proportional to solve the unknowns. The key to using this method is to clarify the known quantities and unknown ones
