研究反应物的化学计量数与产物之间的关系时,使用类似数轴的方法可以收到的直观形象的效果.许多化学反应,随着反应物的比例不同,产物就有所不同.而每一个恰好完全反应的反应物的物质的量的比例关系,就相当于数学的一个极值点.极值点一旦确定,就确定了反应的区间,反应物有什么样的比例关系,就一定会落在其中的一个区间内,于是我们就可以利用极值点去划分反应区间,去判断反应产物和过量物质.这
When studying the relationship between the stoichiometry of a reactant and the product, the effect of an intuitive image can be obtained using a method similar to the number of axes. Many chemical reactions, with different ratios of the reactants, produce different products. Exactly the exact reaction of reactant material quantity ratio, it is equivalent to an extreme point of mathematics.Once the extreme point is determined, to determine the reaction interval, reactants have any kind of proportional relationship, it will certainly fall In one of these intervals, we can use the extreme point to partition the reaction interval to determine the reaction product and excess material.
