It establishes that: Metal + H2O (g) — ? • Active 2 years, 10 months ago. Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. Generally metal react with steam to form metal oxide and hydrogen gas. Even when this is done, the iron does not glow and burn like magnesium does. 4 moles of steam (H 2 O) are required to convert 3 moles of Fe into its oxide. Iron reacts to form i r o n ( I I , I I I ) oxide [ F e O + F e 2 O 3 ] and H 2 gas.
