Question

what happen when iron reacts with steam write a balanced chemical equation for the reaction​

Answer 1

Answer:

Explanation:

Iron can oxidize to Fe+3 or Fe+2, and you mostly get iron hydroxides and hydrogen gas:

oxidation of Fe to Fe+3 gives you:

2 Fe + 6 H2O → 2 Fe(OH)3 + 3 H2

… or Fe+2:

Fe + 2 H2O → Fe(OH)2 + 2 H2

These iron hydroxides are pretty INsoluble in water, so they precipitate out.

Note that these are dependent on pH. In an acidic solution, you won’t have hydroxides forming.

Iron in water with an electrolyte present, such as sodium chloride, will rust quickly, reacting with dissolved oxygen to produce iron (III) oxide:

4 Fe + 3 O2 → 2 Fe2O3
