实验步骤如下:①切取一小块金属钠,用滤纸完全吸干煤油,再除去表面的氧化层,放进干燥的E中;
②打开分液漏斗的活塞,使B中的反应进行一段时间后,再点燃E处的酒精灯。
实验现象如下:钠在充满C02气体的玻璃管中剧烈燃烧起来,产生大量的白烟;玻璃管中有黑色物质生成;待玻璃管冷却后,管壁上附着一层白色物质。
请回答下列问题:
(1)C中盛放的试剂是 ,作用是 。D中盛放的试剂是 ,作用是 。
(2)B中的反应进行一段时间后,再点燃E处的酒精灯的目的是 。
(3)该同学将白色物质和黑色物质分别溶于水,发现黑色物质不溶于水,白色物质能溶于水。由此,该同学得出结论,该黑色物质是Na与C02反应生成的碳单质,则其他生成物还应该有 。
(4)请设计一实验方案验证玻璃管内Na与C02反应生成的白色物质的成分,并写出实验步骤、现象和结论 。
(5)若先点燃E处的酒精灯,再打开分液漏斗的活塞,写出此时玻璃管E中可能发生的反应的化学方程式 。 查看习题详情和答案>>

Dear Mr. Heppell,
I’m Sabrina Akhtar studying in a high school and I’ve noticed that forests are disappearing.
You know, more and more forests are disappearing around the world each year. This is because of many different reasons including farming, tourism pollution, etc. If we stop doing these things, there will be a good future for people of tomorrow.
Now I’m writing to ask you to help stop forests from disappearing. You can help by getting shops to stop selling paper made from trees and changing to tree-free paper ( paper not made from trees ). This will help forests so much. There are many things we can do to help protect forests. By changing the little things, we can make a big difference.
If you would like to contact me, please see the above address or e-mail me at shazadinol @ hotmail. co. uk. Thank you for taking your time in reading this letter.
Yours sincerely
Sabrina Akhtar
