Question

In the reaction Fe2O₃ + 3H₂ → 2Fe + 3H₂O, which substance is the reducing agent?

1) Fe2O₃
2) H₂
3) Fe
4) H₂O

Answer 1

In the reaction Fe2O₃ + 3H₂ → 2Fe + 3H₂O, H₂ is the reducing agent.

Step-by-step explanation:

In the reaction Fe2O₃ + 3H₂ → 2Fe + 3H₂O, H₂ is the reducing agent.

A reducing agent is a substance that donates electrons and gets oxidized in a reaction. In this reaction, hydrogen gas (H₂) is being oxidized to form water (H₂O). Since it is losing electrons, it is the reducing agent.

On the other hand, Fe₂O₃ is being reduced to form iron (Fe). It gains electrons and is therefore the oxidizing agent.
