回答问题：⑴①中反应的化学方程式为；⑵化合物I的电子式为，它的空间结构是；⑶1.6gG溶于盐酸，得到的溶液与铜粉完全反应，计算至少所需的铜粉的质量（写出离子方程式和计算过程）；⑷C与过量NaOH溶液反应的离子方程式为，反应后溶于与过量化合物I反应的离子方程式为；⑸E在I中燃烧观察到的现象是。
（2011年）27答案：⑴Al+ Fe2O3Fe+ Al2O3⑵⑶2Fe3++Cu=2 Fe2++ Cu2+n(Fe2O3)=0.01mol，依据离子方程式，则n(Cu )= 0.01mol，m(Cu )=0.64g.。
⑷2 Al + 2OH- + 2 H2O=2AlO2- + 3H2↑AlO2- + CO2 + 2H2O = Al(OH)3↓+ HCO3-⑸剧烈燃烧，放出热量，生成黑色固体和白色固体。
（2012年）26．(14分) 铁是应用最广泛的金属，铁的卤化物、氧化物以及高价铁的含氧酸盐均为重要化合物。
(1)要确定铁的某氯化物FeCl x的化学式，可用离子交换和漓定的方法。
实验中称取0.54 g的FeCl x样品，溶解后先进行阳离子交换预处理，再通过含有饱和OH－的阴离子交换柱，使Cl－和OH－发生交换。
交换完成后，流出溶液的OH－用0.40 mol/L的盐酸滴定，滴至终点时消耗盐酸25.0 mL。
计算该样品中氯的物质的量，并求出FeCl x中，x值：(列出计算过程)；(2)现有一含有FeCl2和FeCl3的混合物样品，采用上述方法测得n(Fe):n(Cl)=1:2.1，则该洋品中FeCl3的物质的量分数为__________。
