Question

what is redox reaction 1substance oxidsed and the substance reduced.2the oxidising agent and the reducing agent in the following reaction....FE2O3+3CO_2FE+3CO2

Answer 1

When reduction and oxidation reaction occur simultaniously the it is known as redox reaction.
Sub oxi.-2CO
Sub red.-Fe2
Oxi agent - Fe2
Red agent-3CcOo

Answer 2

Redox reaction is a reaction in which both Reduction and Oxidation takes place simultaneously.
1.C has been oxidised from +2 to +4 and Fe is reduced from +3 to +2
2.CO is the oxidising agent and Fe2O3 is the reducing agent
