Question

Please help! assign oxidation numbers to all the atoms in the following equation, write each half reaction, and then identify which element is oxidized and which is reduced.

Answer 1

Cl2 (0)+ 2H(1+)Br(1-) --> 2H(1+)Cl(1-) +Br(0)

Oxidized= HCl, Cl is oxidized

Reduced=Br, 2HBr is reduced

Oxidized Half-Reaction= Cl + 1e--> Cl

Reduced Half Reaction= Br --> Br+ 1e

Step-by-step explanation:

Chlorine loses its electron when it bonds with hydrogen= oxidation

Bromine gains electrons when it breaks its bond with hydrogen= reduction

Answer 2

Step-by-step explanation:

Cl2 would be 0 and in 2HCl it would be -1 so it is reduced

In br First it would be -1 then 0 so it oxidized
