A~J分别表示中学化学中常见的物质,它们之间的相互转化关系如图

AJ分别表示中学化学中常见的物质,它们之间的相互转化关系如图所示(部分反应物、生成物没有列出)。已知:G为金属元素的固态氧化物(常温下);ABCDEF六种物质中均含有同一种元素。(已知F为红褐色沉淀)

       

    请填写下列空白:

    1)物质G的化学式是________

    2)写出反应⑤的化学方程式________,写出反应④的离子方程式________

    3)反应①~⑥中,不属于氧化还原反应的是________。(填序号)。

答案

1Al2O3

    2Fe3O4+8HCl2FeCl3+FeCl2+4H2O  2Al+2OH+2H2O2AlO2+3H2  3)⑤

【解析】本题的突破口为某金属元素的固态氧化物G能电解且可与NaOH溶液反应,由此可确定GAl2O3,进而确定IAlHO2;由F为红褐色沉淀可推知FFe(OH)3EFe(OH)2CFeCl3,由此可推出B中既有+3价的Fe、又有+2价的Fe,应为Fe3O4AFe
