Fe is oxidised. Oxidation can be identified in 3 main ways:
- Loss of electrons
- Gain in Oxygen
- Loss of Hydrogen
In the above, elemental iron gains oxygen so it is oxidised. Some elements such as oxygen and hydrogen are taken to have a fixed oxidation state when in a compound. For Oxygen it is -2 and Hydrogen it is +1. An element by itself has no oxidation state, so it is taken to be 0. Using this you can calculate the oxidation state of the iron. Given that there are 3 oxygen ions in Fe2O3, so 3 x -2 = -6 oxidation state. Given that Fe2O3 is not charged a +6 charge is required to balance the -6. So this +6 is divided across the 2 iron ions to have +3 charge each. So the overall oxidation state change for iron is from 0 to +3.

Would burning of matchstick be a chemical reaction?
yes it will be a chemical reaction..as the head of the match stick is being oxidized to burn. so here the oxidation reaction will take place.
Why is gasoline a chemical energy?
Gasoline is a combination of several hydrocarbons which when oxidized (chemical reaction) release heat energy.
What is oxidized and what is reduced in the following reaction Al3 Br2-- 2 AlBr3?
The reaction as written isn't balanced. It should be 2Al + 3Br2 ==> 2AlBr3In this case Al is oxidized and Br2 is reduced
What element is oxidized in this reaction FeO CO--Fe CO2?
The material that is oxidized in the given reaction is Iron. Fe2O3 is iron oxide which can occur naturally as the mineral magnetite.
Which of the following tends to increase the rate of a chemical reaction?
Increasing the temperature of the reactants can increase the rate of the chemical reaction.
Is something that is easily oxidized a physical or chemical property?
Oxidation is a chemical reaction, so it is a chemical property.
Which component is affected when a catalyst is added to a chemical reaction?
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.
