Question : 26

Total: 36

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) → 2H2O(g)
2 volume + 1 volume → 2 volume
10 volume + 5 volume → 10 volume
Thus, 10 volumes of H2O vapour will be produced.
