钢铁是使用最多的金属材料。在今年的化学活动周中，某校兴趣小组的同学在老师指导下做了二个有关铁的实验。

实验一：用干燥纯净的一氧化碳还原氧化铁实验装置如下图：

其中A是实验室用草酸（H₂C₂O₄）和浓硫酸加热制取一氧化碳的气体发生装置，反应的化学方程式是：H₂C₂O₄H₂O+CO₂↑+CO↑。请回答下列问题：

(1)B装置中发生反应的化学方程式是___________________。

(2)C装置无明显现象，C装置的作用是___________。D装置中浓硫酸的作用是_____________。

(3)E装置中的实验现象是____________________。

(4)F装置的作用是_____________、______________。

实验二：铝粉和氧化铁粉末反应（铝热反应）实验装置如下图：

图中纸漏斗由两张滤纸折叠成漏斗状套在一起，使四周都有四层，点燃镁条后观察到的现象：镁条剧烈燃烧，发出耀眼的白光，放出大量的热，纸漏斗的下部被烧穿，有熔融物落入细沙中。实验后老师作了如下提示：实验中镁条和氯酸钾的作用是提供反应所需的高温条件，铝粉和氧化铁粉末在高温条件下的反应叫铝热反应，属于置换反应，该反应常用于焊接钢轨。请写出该反应的化学方程式________________。该反应中单质铝与一氧化碳有相似的___________（填“氧化”或“还原”）性。实验后同学们对金属与金属氧化物间的反应产生兴趣，激发了探究热情。

【提出问题】任何金属与金属氧化物在高温条件下都能反应吗？同学们在请教老师后设计了如下实验方案并进行了探究。

【实验方案】

【实验总结】金属与金属氧化物在高温条件下有些能反应，有些不能反应。

【反思拓展】金属与金属氧化物在高温条件下反应的规律和金属与________的反应相似。
