Question

Give the reaction of steam with ?

(a) Magnesium

(b )Aluminium

(c ) Iron

Answer 1

1. The reaction of steam with Magnesium :

$M{g}_{\left(s\right)}+H_{2}O{}_{\left(g\right)}⟶MgO{}_{\left(s\right)}+H_{2\left(g\right)}$

2.The reaction of steam with Aluminium:

$2Al+6H_{2}O⟶2Al\left(OH\right){}_3+3H_2$

3.The reaction of steam with Iron:

$3F{e}_{\left(s\right)}+4H_{2}O{}_{\left(g\right)}⟶F{e}_3{O}_{4\left(s\right)}+4H_{2\left(g\right)}$
