Question

what are the Redox reaction ? identify the substance that are oxidised and substance that are reduced in the following reactions :.

a) 2H2s(g)+so2(g) -->3s(s)+2H2oO(l)

b)cuo(S)+H2(g)-->Cu(s)+H2O(l)

c)MNO2(s)+4HCl (l)-->MNCl2(s)+2H2O(l)+Cl2(g) ^​

Answer 1

An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
