Reactions of Iron with Steam:
When iron reacts with steam, it forms iron(III) oxide and hydrogen gas. The chemical equation for this reaction is:
3Fe(s) + 4H2O(g) β Fe3O4(s) + 4H2(g)
Reactions of Calcium and Potassium with Water:
When calcium reacts with water, it forms calcium hydroxide and hydrogen gas. The chemical equation for this reaction is:
Ca(s) + 2H2O(l) β Ca(OH)2(aq) + H2(g)
When potassium reacts with water, it forms potassium hydroxide and hydrogen gas. The chemical equation for this reaction is:
2K(s) + 2H2O(l) β 2KOH(aq) + H2(g)
