计算题中的表格主要是记录同一个反应的多组实验数据,根据这些数据解答有关问题。解答表格类计算题时应掌握以下几个问题。一、涉及题型1.反应中的固体为纯净物:①加热固体,记录反应过程中剩余固体质量;②固体与溶液之间发生反应生成气体,记录反应中反应物的质量与生成的气体质量关系,或记录反应中反应物的质量与反应后总质量关系;③溶液与溶液之间发生反应生成气体或沉淀,记录反应中反应物的质量与生成的气体或沉淀质量关系,或记录反应中反应物的质量与反应后总质
The tables in the calculation questions mainly record multiple sets of experimental data of the same reaction, and according to these data, answer relevant questions. The following questions should be answered when solving the form class calculation questions. First, involving the questions 1. Solid reaction was pure: ① heating the solid, recording the remaining solid mass during the reaction; ② reaction between the solid and the solution generated gas, the reaction of reactants recorded in the quality of the gas generated and the quality Relationship, or record the reaction between the mass of the reaction and the total mass of the reaction after the reaction; ③ reaction between the solution and the solution to generate gas or precipitation, the reaction of the reaction mass was recorded and the quality of the resulting gas or precipitation, or recording reaction The mass of reactants and the total mass after reaction
