Answer:

D. [tex]2NaBr + Cl_2\rightarrow 2NaCl + Br_2[/tex]

Explanation:

Hello!

In this case, for the given set of chemical reactions, it is possible to infer that D. is a categorized as redox due to the following:

Since both chlorine and bromine remain as diatomic gases, their oxidation states in such a form is 0, but as anions with lithium cations they have a charge of - according to the following reaction and half-reactions:

[tex]2NaBr + Cl_2\rightarrow 2NaCl + Br_2[/tex]

[tex]Cl_2^0+2e^-\rightarrow 2Cl ^-\\\\2Br^- \rightarrow Br_2^0+2e^-[/tex]

Unlike the other reactions whereas no change in the oxidation states is evidenced.
