Answer:
Redox reaction.
Explanation:
Hello,
In this case, the required chemical reaction is:
[tex]H_2(g)+O_2(g)\rightarrow H_2O(g)[/tex]
Which balanced is:
[tex]2H_2(g)+O_2(g)\rightarrow 2H_2O(g)[/tex]
Thus, if we write the oxidation numbers:
[tex]2H_2^0(g)+O_2^{-2}(g)\rightarrow 2H_2^{+1}O^{-2}(g)[/tex]
Hence we evidence how the hydrogen is oxidized from 0 +1 and oxygen is reduced from 0 to -2, therefore the hydrogen is a reducing agent and the oxygen is an oxidizing agent. Thereby, this is a redox reaction.
Best regards.
