So I did some Calculations and I might be wrong but in the Process of breaking down Tungsten tri-oxide plus 6 Hydrogen Gas into Tungsten Dust plus 9 buckets of water, the following equation looks like: 6H^2+4WO^3==Mixing==>W+9H^2O. Where does the extra 6 hydrogen come from to form the extra water …

2 H + 1 O = 3 H2O, so 2 + 1 = 3. So 6 H + 4 WO3 = 1 W + 9 H2O. so 6 + 4 = 1 + 9 = 10 Simple Maths based on Unit amounts and not mass or Volume.
