Q.

what are redox reactions ??

Answer 1

Answer:

Redox reaction is a reaction in which oxidation and reduction take place stimulatanously.

Explanation:

what is oxidation reaction ?

~the reaction in which oxide is consumed and H2 is liberted is called Oxidation reaction.

CH4(methane) -----> C+ 2H2

heat 600°c

What is reduction reaction ?

~It is just opposite of oxidation. ie H2 is consumed and O2 is liberted.

H2 + CL2 -----> 2HCL

(Hydrogen gas) + (chlorine gas) ------> (hydrochloric acid)

________________________

Combined oxidation and reduction -

CuO + H2 -----> Cu + H2O

(copper oxide) + (hydrogen)---> (copper) + (water)

Answer 2

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.
