Q.3 Which the following statements about the given reaction are correct: 3Fe(s) + 4H2O(g)- Fe203 (S) + 4H2(g)
i) Iron metal is getting oxidized
ii) Water is getting reduced
iii) Water is acting as reducing agent
iv) Water is acting as oxidizine agent
a) (i), (ii) and (iii) b)(iii) and (iv)
c) (i), (ii) and (iv) d) (ii) and (iv)

The statements which are correct are;

c) (i), (ii) and (iv)

Explanation:

The chemical equation is presented as follows;

2Fe(s) + 3H₂O(g) → 3Fe₂O₃(s) + 3H₂(g)

Therefore, we have;

i) The iron gains oxygen atoms and therefore gets oxidized

The iron loses 3 electrons each to become oxidized to Fe³⁺ in Fe₂O₃

ii) The water loses oxygen and therefore it is getting reduced

iv) The water donates oxygen and therefore it is acting as the oxidizing agent

The correct options are (i), (ii) and (iv).

neutrons are in the middle of the atom and the electrons, which are much smaller.
