Question : 26 of 36
Marks: +1, -0
If ten volumes of dihydrogen gas reacts with five volumes of dioxygen gas, how many volumes of water vapour would be produced?
Solution:  
2H2(g)+O2(g)2H_{2(g)} + O_{2(g)} → 2H2O(g)2H_2O_(g)
2 volume + 1 volume → 2 volume
10 volume + 5 volume → 10 volume
Thus, 10 volumes of H2OH_2O vapour will be produced.
