The carbon and hydrogen atoms are 'competing' for electrons

Answer: The carbon and hydrogen atoms fight for the electrons.

Explanation:

Redox reactions are defined as the reactions in which reduction and oxidation reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of this substance is increased and the substance gets oxidized.

[tex]X\rightarrow X^{n+}+ne^-[/tex]

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of this substance gets reduced and the substance gets reduced.

[tex]X^{n+}+ne^-\rightarrow X[/tex]

In a redox reaction, one atom loose electrons and another atom gains electrons.

For the given chemical reaction:

[tex]C(s)+H_2O(g)\rightarrow CO(g)+H_2(g)[/tex]

Oxidation half reaction:  [tex]C(s)\rightarrow C^{2+}+2e^-[/tex]

Reduction half reaction: [tex]2H^++2e^-\rightarrow H_2[/tex]

As, carbon is loosing electrons. so, it is getting oxidized and hydrogen is gaining electrons. So, it is getting reduced.

Hence, the carbon and hydrogen atoms fight for the electrons.
