实验目的制取氧气实验用品高锰酸钾,试管,铁架台,酒精灯,集气瓶实验步骤1
将适量高锰酸钾放入试管2.将试管固定在铁架台上,用酒精灯加热3.收集氧气检验氧气把带火星的木条放在集气瓶口,木条燃烧,表明氧气集满实验结论高锰酸钾受热分解可产生氧气注意:1.词数:100 左右;2.可适当增加细节,使行文连贯
3.参考词汇:高锰酸钾 potassium permanganate;铁架台 iron support;酒精灯 alcohol burner;集气瓶 gas jarOne possible versionHow to produce oxygenHere is a report on a simple chemical experiment,which shows us how we can produce oxygen
Aim:to produce oxygenApparatus:potassium permanganate,test tube,iron support,alcohol burner,gas jarMethod:1.Put a proper amount of potassium permanganate into a test tube
2.Fix the test tube to an iron support and then heat the tube with an alcohol burner
3.After a while,we can collect oxygen with a gas jar
Result:If a lighted pie
