In this reaction, Cr2O3 is the oxidizing agent which will oxidize Al to Al2O3.

Al is the reducing agent that will reduce Cr2O3 to Cr.

An oxidizing agent has the property of oxidizing another molecule (giving it one or more oxygen atoms) by being reduced.

A reducing agent has the property of reducing another molecule (by removing one or more oxygen molecules) by being oxidized.

Cr2O3+ 2Al -----------> 2Cr+ Al2O3

Cr2O3--------2Cr.
( oxidation no. of cr +3 to +1 means hain of electron so it act as oxidizing agent)

similarly,

2Al------> Al2O3
( oxidation no. of Al +1 to +3 means loss of electron so it act as reducing agent)

A pure element unbound or in a diatomic state, such as cl2, always has an oxidation number of ________. a. 1 b. 2 c. magnitude e
nignag [31]

A pure element unbound or in a diatomic state, such as cl2, always has an oxidation number of 0 (zero).

<h3>Why does pure element or a diatomic molecule has zero oxidation state?</h3>

In a neutral substance with atoms of only one element, the oxidation number of an atom is zero. As a result, the oxidation number of the atoms in O2, O3, P4, S8, and aluminum metal is 0. The oxidation numbers for an element in its normal state will be zero. O2 and Cl2 are diatomic gas molecules that occur naturally, thus when they are in that state, they have an oxidation state of zero. Metals like zinc will also have an oxidation number of zero if they are in their natural solid state.

O2 and Cl2 are neutral diatomic, hence they will always have a zero oxidation state. It is impossible for one oxygen atom to have a negative 2 charge while the other has a positive 2. The oxidation states should be 0 if the elements are solids, liquids, or any type of diatomic molecule.
