Hi everyone.
00:01
So in this question, a strip of aluminum metal react with oxygen gas to produce aluminum oxide.
00:06
So write down the balanced chemical equation and what is the oxidizing agent in the redox reaction? so student, let us understand the concept in this question, that is the oxidation, reduction, oxidizing agent and reducing agent.
00:19
So one by one we can discuss about this.
00:22
So oxidation is the process in which increase in oxidation number of an element or in terms of electron loss of electrons that is known as oxidation.
00:29
Coming to, the reduction reduction is the process in which a decrease in oxidation number of an element or in terms of electron gain of electrons that is known as reduction oxidation and reduction both are opposite right and a redox reaction is the reaction in which both oxidation and a reduction that can take place simultaneously so this type of reaction that is known as redox reaction in which both oxidation and reduction that can take this simultaneously so now let us understand about the oxidizing agent so oxidizing agent are those species which can oxidize other but it's self -reduced and reducing agent are those which can reduce other but itself oxidized right so let us see the reaction so here when aluminum solid react with oxygen gas they can form aluminum oxide now we have to balance this reaction so i'm using the stockometric coefficient four in aluminum stockometer coefficient two in aluminum oxide and stockometry coefficient three in oxygen so that we have four aluminum atom on both side and six oxygen atom on both side of this reaction now this reaction is balanced.

Now let us find out the oxidation number of each element in this reaction.
01:36
So oxidation number of aluminum that is zero...
