In a hydrogen fuel cell, hydrogen gas and oxygen gas are combined to form water. Write the balanced chemical equation describing this reaction using the lowest whole‑number coefficients.classify each reaction as a redox reaction or a non‐redox reaction. redox non‐redox

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.
