实验是镁条在空气中点燃,翻译下面的内容即可,我翻译了部分,有错误请帮忙修正,不要太复杂,没有加括号的是没有翻译的,拒绝翻译器
Aim:了解活泼金属与空气加热的反应
Apparatus:酒精灯(Bunsen burner)、坩埚钳(tongs)、火柴(match)、镁条(magnesium)
Method:1、用火柴点燃酒精灯
2、用坩埚钳夹起镁条,放在酒精灯上点燃
Result:发出强光,放热,生成氧化物
Conclusion:活泼金属与空气加热后剧烈反应
另外翻译:接下来,就是见证奇迹的时刻(Next,it's time to witness the miracle)

The experiment is magnesium in lighting up in the air article, understand and lively metal and air heating response. We need to alcohol lamp, crucible clamp, matches and article magnesium. First of all, with the match to light lamp alcohol. Then use crucible clamped up article magnesium. On alcohol light lit. Experimental phenomenon is a strong light, heat, generating oxide. And then found lively and metal and air heating jitters after. Next,Next,it's time to witness the miracle
