Question

please tell me why the different different reactants give the same product on oxidation????

plzzz

Answer 1

 redox (or oxidation-reduction) reaction is a type of chemical reaction that involves a transfer of electrons between two species. 

What is a "species"?

\text{Fe}_2 \text{O}_3+2 \text{Al} \rightarrow 2 \text{Fe}+\text{Al}_2 \text O_3

\text{Fe}_2 \text{O}_3\text{Al}\text{Fe}\text{Al}_2 \text O_3

We can tell there has been a transfer of electrons if there is any change in the oxidation number between the reactants and the products.
