存在有过量反应物的化学算题的计算方法,可以总结和概括成:求出化学方程式中交叉方向上反应物量的乘积,乘积大的、其上方反应物过量,乘积小的、其上方反应物是有限剂量,而后用有限剂量反应物的量来计算答案。如果用上述大的乘积减小的乘积的差,除以1摩尔有限剂量反应物的质量与反应系数的乘积,便得出有限剂量反应物用质量表示它的量时、过量反应物反应后的剩余
There are calculation methods for chemical calculations with excess reactants, which can be summarized and summed up as follows: The product of the amount of reactants in the crosswise direction in the chemical equation is found. The product with a large product, the overlying reactants above it, and the product with a small product above it. It is a limited dose and then the answer is calculated using the amount of the limited dose of reactants. If the difference between the product of the above-mentioned large product reduction is divided by the product of the mass of 1 molar finite-dose reactant and the reaction coefficient, the finite-dose reactant is expressed as its mass by the amount of excess reactant.
