Question

what is redox reqction?identify the substance oxidised and the substance reduced in the following reactions:1)mno2 + 4hcl ------ mncl2 + 2 h2o + cl2 2)cup + H2 ----- cu +h2o

Answer 1

In a reaction when both oxidation takes place means when oxygen is added or hydrogen is reduced and reduction takes place means oxygen is reduced or hydrogen is added then the reaction is known as redox reaction.

1. MnO is reduced to MnCl and HCl is oxidised to H2O.
2..CuO is reduced to Cu and H2 is oxidised to H2O.

hope this helps you..
plz mark it as a brainliest answer..

Answer 2

Hey buddy✌✌.

_____________________
1) substance oxidized >> HCL.
And substance reduce >> MnO2.

2) reduction occur >> cuO to cu.
and oxidation occur >> H2 from H2O.

Dear:) hope its helps ⛄☃️
