The following question has four choices out of which ONLY ONE is correct.

The oxidation number of carbon in CH₂O is

For the reaction between KMnO₄ and H₂O₂, the number of electrons transferred per mole of H₂O₂ is:

Oxidation and reduction always occur simultaneously, hence, the word “redox” was coined for this class of chemical reactions. In the following redox reaction, identify the species undergoing oxidation and reduction:

3Fe₃O₄(s) + 8 Al (s) → 9 Fe (s) + 4Al₂O₃(s)

Oxidation number denotes the oxidation state of an element in a compound ascertained on the basis that electron in a covalent bond belong
