Question

iron react with icecream to give out magnetic oxide of iron and hydrogen please explain ​

Answer 1

Answer:

3Fe(s)+4H

2

O(g)→Fe

3

O

4

(s)+4H

(g)

When ‘iron’ reacts with steam it forms “iron (II, III) oxide” and also released “hydrogen gas”.

Here “iron (II, III) oxide” can be formulated as \mathrm{Fe}_{3} \mathrm{O}_{4}Fe

3

O

4

therefore the reaction must be:

\bold{\mathrm{Fe}(\mathrm{s})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \rightarrow \mathrm{Fe}_{3} \mathrm{O}_{4}(\mathrm{s})+\mathrm{H}_{2}(\mathrm{g})}Fe(s)+H

2

O(g)→Fe 3 O 4 (s)+H 2 (g

Now to balance this reaction we need to add coefficient with each one of the reactant and product to make sure that the ‘number of atoms’ will be same at both sides.

Hence the balance chemical equation will

Answer 2

Answer:

Which of the following oxide(s) of iron would be obtained on prolonged reaction of iron with steam? Explanation: Prolong heating of red hot iron with steam form Fe3O4 with hydrogen gas.

First of all, the basic equation will be:

Fe + H₂O → Fe₂O₃ + H₂

The balanced equation will be:

2 Fe(s) + 3 H₂O(g) → Fe₂O₃(s) + 3 H₂(g)
