用CO_2给气球充气化学反应促成了一些很不错的实验。通过一个饮料瓶收集利用小苏打和柠檬汁反应生成的二氧化碳气体,让气体通过软饮料瓶排出并进入你准备好的气球。需要准备的材料:A.气球B.大约40毫升水C.饮料瓶D.吸管E.一瓶柠檬的果汁F.1茶匙小苏打实验步骤:在你开始做实验前,要确保气球是伸展开的,让它尽可能地易于充气。把40毫升水倒入饮料瓶。
Gasification of balloons with CO2 gives rise to some very good experiments. Collect carbon dioxide gas from the reaction of baking soda and lemon juice through a drink bottle, allowing the gas to escape through the soft drink bottle and into your prepared balloon. Materials to be prepared: A. balloon B. about 40 ml of water C. beverage bottle D. pipette E. a bottle of lemon juice F.1 teaspoons baking soda Experimental Procedure: Before you start the experiment, make sure the balloon is extended Make it as easy to inflate as possible. Pour 40ml of water into the bottle.
