If ten volumes of dihydrogen gas reacts with five volumes of dioxygen gas, how many volumes of water vapour would be produced?

Answer

Ten volumes

Explanation

Reasction of hydrogen with dioygen can be written as:
`2H_(2(g))+O_(2(g))to 2H+_(2)O_(g)`
Now , two volumes of dihydrogen react with one volume of dihydrogen to produce two volumne of water vapour .
Hence , ten volume of dihydrogen will react with five volumes of dioxygen to proove ten volumes of eater vapour.
