8．佳佳和小洁一起用木炭烧火锅时。不小心把水滴到了高温下赤热的木炭上，火苗一下蹿起很高．她们相约对此进行以下探究．提出问题：是否发生了化学反应?如果是，产物是什么?对空气质量有哪些影响?查阅资料：她们得知，高温下碳能与水反应，生成物有多种．猜想：佳佳认为有H_2、CO生成；小洁认为有H_2、CO和CO_2生成．老师认为她们的猜想都合理，可用实验来验证．
8. Jia Jia and Xiao Jie used charcoal to cook the hot pot together. I accidentally dropped the water on the hot charcoal under high temperature. The flames picked up very quickly. They agreed to make the following inquiry. Ask the question: Did a chemical reaction occur? If so, what is the product? What are the effects on air quality? Check out the data: They learned that carbon can react with water at high temperatures and there are many types of products. Conjecture: Allison believes that H_2 and CO are generated; Xiaojie thinks that H_2, CO, and CO_2 are generated. The teacher thinks their conjecture is reasonable and can be verified by experiment.
