陷阱复杂氧化物的组成与性质例1(上海卷·22)PbO_2是褐色固体,受热分解为Pb的+4价和+2价的混合氧化物,+4价的Pb能氧化浓盐酸生成Cl_2。现将1 mol PbO_2加热分解,得到O_2,向剩余固体中加入足量的浓盐酸得到Cl_2,O_2和Cl_2的物质的量之比为3:2,则剩余固体的组成及物质的量之比是()A.1:1混合的Pb_3O_4、PbOB.1:2混合的PbO_2、Pb_3O_4C.1:4:1混合的PbO_2、Pb_3O_4、PbOD.1:1:4混合的PbO_2、Pb_3O_4、PbO
Composition and Properties of Traps with Complex Oxides Example 1 (Shanghai Vol. 22) PbO 2 is a brown solid that is thermally decomposed into the +4 valence and +2 valence mixed oxides of Pb. + 4 valence Pb oxidizes concentrated hydrochloric acid to form Cl 2. Now 1mol PbO_2 heat decomposition to obtain O_2, to the remaining solids by adding sufficient concentrated hydrochloric acid to get Cl_2, O_2 and Cl_2 material amount ratio of 3: 2, then the remaining solid composition and the amount of material ratio () Mixed Pb_3O_4, PbOB.1: 2 mixed PbO_2, Pb_3O_4C.1: 4: 1 PbO_2, Pb_3O_4, PbOD.1: 1: 4 mixed PbO_2, Pb_3O_4, PbO
