一、问题的提出1.2006年全国高考上海化学卷26题(A)是一道适合使用二期课改新教材的考生解答的分叉实验题(题略)。原题通过成分检验实验(将反应后所得固体M与H2SO4反应)后认为,在隔绝空气的条件下,Fe与S反应所得“(1)①
I. Proposal of Questions 1. The 26 questions (A) in the 2006 Shanghai National Chemistry Examination for the National College Entrance Examination were bifurcated experimental questions that were suitable for the candidates who used the second-grade curriculum to modify the new teaching materials. After the original question passes the composition test (reacts the solid M after reaction and H2SO4 reaction), it is considered that under the condition of air-isolation, Fe reacts with S to obtain ”(1) 1
