Hydrogen part 1 Production Hydrogen gas may be produced by several methods. It is commercially obtained by electrolysis of water. It also is made industrially by the reaction of steam with methane or coke: CH4 + H2O → CO + 3H2 C + H2O → CO + H2 CO + H2O → CO2 + H2 Equilibrate the equation: Do the same with next 2 reactions!
