中产生的气体的组成看法不一，提出了以下几种假设：该气体是CO；该气体是H2。请你推测该气体还可能是什么气体？提示：O2(3)设计一个实验，证明你在(2)中的推测(写出简要操作步骤，反应现象和结论)。操作步骤反应现象结论提示：操作步骤：收集气体，将带火星的木条靠近集气瓶口(或试管口)；反应现象：带火星的木条复燃；结论：该气体是氧气。(4)写出该淡黄色固体与稀盐酸反应的离子方程式。提示：2Na2O2 4H=4NaO2 2H2O 即时训练1将少量稀盐酸滴加到盛有碳酸钙的U形管中，可观察到U形管中的脱脂棉剧烈燃烧。(1)稀盐酸与碳酸钙反应的离子方程式是_ _。(2)从脱脂棉的燃烧可以推出关于Na2O2与CO2反应的结论是a._，b._ _。(3)Na2O2与 CO2反应的化学方程式是_ _。还原剂是 _，氧化剂是 _。解析：稀盐酸与碳酸钙反应放出CO2，CO2遇 Na2O2发生反应：2Na2O2 2CO2=2Na2CO3O2，该反应放热，使脱脂棉的温度很容易达到其着火点，且生成的O2助燃，故脱脂棉会剧烈燃烧起来。在上述反应中只有Na2O2中的氧元素的化合价发生变化，故Na2O2既是氧化剂，又是还原剂。答案：(1)2HCaCO3=Ca2CO2 H2O(2)反应生成O2反应放热(3)2Na2O22CO2=2Na2CO3O2Na2O2Na2O2文档编码:CQ9S9H2D6J9

中蜡烛火焰熄灭；关闭活塞()时，A中反应自行停止。试根据上述实验事实，回答以下各问题：(1)A 中发生的化学反应是_。(2)在装置 B中的淡黄色粉末是_。(3)在干燥管C中的白色固体应为_。解析：此题以蜡烛火焰的明亮和熄灭为突破口。明亮一定是通入了O2，而熄灭一般是CO2。由此可确定B中是 Na2O2(淡黄色粉末)和 CO2的反应；从而可知A是产生 CO2的简易启普发生器，C中是一个不与CO2反应的白色固体，即是中性或酸性的固体干燥剂。答案：(1)CaCO32HCl=CaCl2 CO2 H2O(2)Na2O2(3)CaCl2或 P2O5(二)氢氧化亚铁的制备方法教材中有关Fe(OH)2的制备方法，实际上只能观察到瞬间的Fe(OH)2白色沉淀(几乎分辨不出)。要较长时间观察到白色沉淀的生成，关键是降低反应体系中氧气的存在量和操作过程中氧气的引入量。方法 1：装置如图甲所示。在试管中加入适量的5%FeSO4溶液，并覆盖一层苯，再用长滴管注入不含O2的 1 mol L1 NaOH溶液。由于苯的液封作用，防止了生成的Fe(OH)2被氧化，因而可较长时间观察到白色的Fe(OH)2沉淀。方法 2：装置如图乙所示。实验时，先打开活塞K，再将分液漏斗中的旋塞打开，使稀硫酸与铁粉作用，用产生的H2排出装置中的空气；然后闭关K，使生成的H2将试管中的FeSO4溶液压入 NaOH 溶液中，则可较长时间观察到生成的Fe(OH)2白色沉淀。若拔去广口瓶上的橡胶塞，则白色沉淀迅速变成灰绿色，最后变成红褐色。图甲图乙文档编码:CQ9S9H2D6J9 HE4Y3R5T8F8 ZX4K5L8S7W6文档编码:CQ9S9H2D6J9 HE4Y3R5T8F8 ZX4K5L8S7W6文档编码:CQ9S9H2D6J9 HE4Y3R5T8F8
