Question

Write chemical equations for the reactions taking place when: (i) Manganese dioxide is heated with aluminium powder. (ii) Steam is passed over red hot iron.

Accepted Answer

(i) $3	ext{MnO}_2(s) + 4	ext{Al}(s) ightarrow 3	ext{Mn}(l) + 2	ext{Al}_2	ext{O}_3(s) + 	ext{Heat}$ (ii) $3	ext{Fe}(s) + 4	ext{H}_2	ext{O}(g) ightarrow 	ext{Fe}_3	ext{O}_4(s) + 4	ext{H}_2(g)$
