九年级化学教材中,蜡烛不完全燃烧实验只能看到生成炭黑而无法看到生成一氧化碳等可燃性气体。用数字化实验探究了蜡烛不完全燃烧,证实不完全燃烧不仅发生在蜡烛与氧气接触不充分的情况下,也发生在氧气接触充分但含量不足时,前者生成一氧化碳的量大约是后者的10倍。 In the ninth grade chemistry textbook, the incomplete combustion test of the candle can only see the generation of carbon black and can not see the generation of flammable gas such as carbon monoxide. In-depth experiments explored the incomplete combustion of the candle, demonstrating that incomplete combustion occurs not only when the candle does not have enough contact with oxygen, but also when oxygen is present at a sufficient but insufficient level, producing about 10 times as much carbon monoxide as the latter .
