Our (13) acquaintance with them comes not from our mother’s (14) or from the talk of our school-mates, (15) from books that we read, lectures that we (16) , or the more (17) conversation of highly educated speakers who are discussing some particular (18) in a style appropriately elevated above the habitual (19) of everyday life.

(10分)某兴趣小组对物质的性质和成分进行相关探究。

(1)常见金属活动性顺序如下,填写相应的元素符号:

金属活动性由强逐渐减弱 

某同学用硫酸铜溶液把“铁刀变成铜刀”,其反应的化学方程式为         ,该反应的基本反应类型为          

(2)兴趣小组同学用氧化铜与足量的炭粉利用图甲所示的装置进行实验,对生成气体的成分进行探究。

[提出问题]生成的气体中是否含有一氧化碳?

[实验与讨论]

①打开K,缓缓通入干燥的氮气一段时间。

②关闭K,加热至一定温度使之反应,用气囊收集气体样品。

③除去气体样品中的二氧化碳,并将剩余气体收集在集气瓶中,下列装置中最为合理的是      

[实验求证]

将除尽二氧化碳后的气体样品干燥,仍然用图甲所示的装置进行实验,A中的固体应选用       ,B中溶液为澄清石灰水,若A中黑色固体出现了红色,B中澄清石灰水            ,可说明气体样品中含有一氧化碳。

[实验反思]

炭粉还原氧化铜的实验中,若生成的气体中含有一氧化碳,则反应时消耗碳、氧元素的质量比     (填“大于”、“等于”或“小于”)3∶8。
