The oxidation states of iron atoms in compounds $ \left(\mathrm{A}\right),\left(\mathrm{B}\right) \mathrm{and} \left(\mathrm{C}\right)$, respectively, are$ \mathrm{x},\mathrm{y} \mathrm{and} \mathrm{z}$. The sum of $ \mathrm{x},\mathrm{y} \mathrm{and} \mathrm{z}$ is
Oxidation State:
Step 1: Compute the oxidation state of iron in the given compound
Step 2: Compute the sum of
Hence, the sum of is .
