Question

3) Write the equations of the reaction of Al, Zn and Fe with Steam. ​

Answer 1

•When zinc reacts with steam, zinc oxide and hydrogen gas are produced.

Zn(s) + H2O(g) -> ZnO(s) + H2(g)

•Aluminium reacts with water to produce hydrogen gas

2Al(s) + 3H2O(g) -> Al2O3(s) + 3H2(g)

•When red hot iron reacts with steam to form iron (II, III) oxide and hydrogen

3Fe(s) + 4H2O(g) steam -> Fe3O4 (s) + 4H2(g)
