用原子守恒怎样解题啊?急死
现有NO2、O2的混合气体12ML,通入足量水中,充分反映后逸出气体2ML（同温同压下）,则原混合气体中含氧气的体积是?
由参加反应的NO2和O2中所含N原子数与O原来之比为2:5,
剩余气体可能是O2,也可能是NO,社原混合气体中含O2的体积为XML,
则1.若剩余O2,则反映的NO2为(12-X)ML,反映的O2的(X-2)ML,有(12-X):[2(X-2)+2(12-X)]=2:5 得x+4
2.若剩余NO,则反映 的NO2为(6-X)ML,反映的Q2为XML,有(6-X):[2X+2(6-X)]=2:5 得x=1.2
我笨
为什么要列这样的式子呢
(12-X):[2(X-2)+2(12-X)]=2:5
