下图为某套实验装置示意图，无法看到实验说明，加热装置已经省略．

（一）甲同学认为当D处盛放V₂O₅作催化剂时，此套装置可用于合成物质X，并预测E处冰水冷却的U型管中将有固体X出现．

（1）事实上此装置所附实验说明符合甲同学的推断，那么A中所发生的反应的化学反应方程式是:__________，C装置中盛放的液体药品的名称是______________。

（2）甲同学方案中为了提高A装置产物的转化率，可以增大B装置产物的通入量，欲知A、B两装置中产物在D中的通入量，可通过观察__________得知．

（3）本实验在设计上_________（填有、无）缺失之处？若有请给出改进方案。（若无，此问可不答）

（二）乙同学认为若D处盛放铂铑合金网作催化剂，则此套装置也可用于合成物质Y，并预测E处冰水冷却的U型管中将有红棕色气体生成，且越接近U型管底部颜色越浅．

（4）写出乙同学认为的D装置中发生反应的化学方程式_________________________________。

（5）对于A处，乙认为不需加热装置。则A处仪器中分别放置的药品为:分液漏斗中____________圆底烧瓶中_________

（6）若要用上述装置完成乙同学所认为的实验，且C处所起作用与合成X时所起作用基本一致，那么C处的广口瓶应改为__________所装药品为_____________。

Most taxpayers have had enough income tax collected by their employers during the year. So they do not (36) any money. In fact, most Americans get some money back. Last year, the Internal Revenue Service returned at least some money to more than (37) Americans paying individual income tax.
