Question

Write equations for the reactions of
(i) iron with steam
(11) calcium and potassium with water​

Answer 1

Answer:

1. Fe + H2O ------> Fe3O4 + H2

2. Ca + H2O ------> (CaOH)2 + H2

K + H2O ------> KOH + H2

Answer 2

Iron (Fe) + H2O(steam) = Fe3O4(solid) + H2(hydrogen gas)

Calcium (Ca) + H20(liquid) = Ca(OH)2 (aqueous)+ H2 (gas)

K(potassium) + H20 (liquid) = KOH (aqueous) + H2 (hydrogen gas)
