题目:(1997年高考化学试题第26题) 解法1:设生成COx克,CO_2y克。生成水的物质的量n_(H_2O)=10.8/18=0.6mol,由反应前后氢原子守恒和乙醇的分子式C_2H_6O可知:
Title: (Chemical Exam Question No. 26 in the 1997 College Entrance Exam) Solution 1: Let COx g, CO 2 y g. The amount of water-generating material n_(H_2O)=10.8/18=0.6 mol is known from the molecular formula C_2H_6O in which the hydrogen atoms are conserved before and after the reaction and ethanol:
