A、B、C、D、E、F六种物质,它们的组成中有一种元素是相同的,现有下列条件(1)A、B均难溶于水,A在空气中易被氧化成B(2)B受热分解可生成C(3)足量的F加入D的溶液中,充分震荡后,生成浅绿
A、B、C、D、E、F六种物质,它们的组成中有一种元素是相同的,现有下列条件
(1)A、B均难溶于水,A在空气中易被氧化成B
(2)B受热分解可生成C
(3)足量的F加入D的溶液中,充分震荡后,生成浅绿色E溶液
(4)往D溶液中加入AgNO3溶液,可生成难溶于硝酸的白色沉淀,往碳酸里滴入D溶液,震荡,溶液呈紫色
据此
请写出A、B、C、D、E、F的化学式

The Air Jordan 2010 Team was heralded by readers right away for removing the maligned window from the standard Air Jordan 2010. This colorway recently surfaced and ought to be obtainable for your next hoops season.
White perforated leather covers the upper,cheap nike shoes, and bigger holes are used in the area where we’re used to seeing the aforementioned window. The midsole and liner are both navy, and the tongue and laces are dark grey. Is the Team model a positive upgrade?
