1.26 If 10 volumes of dihydrogen gas reacts with five volumes of dioxygen gas, how many volumes of water vapour would be produced?
For the given situation we have the reaction:
Here, 2 volumes of dihydrogen gas react with 1 volume of dioxygen to produce 2 volumes of water vapour.
So, if 10 volumes of dihydrogen gas react with 5 volume of dioxygen then it will produce ( volumes of water vapour.
