as long as the calculation of the chemical equation is investigated, the details are as follows: according to the difference of the gas, the volume of the reacted gas is 448-112 = 336ml. It shows that the mixed gas of CO reacting oxygen and hydrogen is 336ml. According to the chemical equation of the reaction: 2h2 + O2 = = 2H2O, it can be seen that two parts of hydrogen and one part of oxygen just completely react

您好，您的问题我已经看到了，正在整理答案，请稍等一会儿哦~
：此题只要考察化学方程式的计算，具体如下：根据气体的差量可知：反应掉的气体的体积为：448-112=336ml。说明共反应掉氧气与氢气的混合气体为336ml。根据反应的化学方程式：2H2+O2==2H2O可知：两份的氢气与一份的氧气恰好完全反应
第三小题的 c
和第四小题的abc
麻烦都用英文回答
谢谢

再麻烦做一下第四题的abc吧 顺便标明一下序号 ，谢谢
老师请问下大概还需要多久？
老师还在吗？
