00:01 Hello everyone in this question they have given reaction first let me write this those reaction they have given here in first reaction they have given ch4 plus water which gives carbon monoxide plus plus 3h2 plus 3h2 and second reaction here they have given that is 2agno3 2agno3 is going to be reacted with copper it produce cuno3 twice that is copper nitrate plus 2ag and third reaction they have given zn plus 2hcl which gives zncl2 plus h2 zncl2 plus h2 and fourth reaction here they have given that is h plus plus cr2 it is cr2cr 2cro4 2cro4 2 minus which gives cr2o7 2 minus plus plus h2o plus h2o so here they have asked that in first part they have asked that here which which are the following reaction is going to be represent oxidation and reduction reaction so the answer for this question is the equation first second and third that is equation a b c are going to be represent oxidation and reduction reaction so that is equation a b c d is not a equation d is not going to be represent oxidation and reduction reactions here oxidation state h plus in a reactant side is going to be same in product side that is by option d in the equation 4 that is a equation d is not a represent oxidation reduction reactions and second part of this question here they have asked that here they have asked that which one is undergoes oxidation and which one is undergoes reduction so let us consider in equation a equation first equation here ch4 ch4 here undergoes oxidation and and h2o is undergoes reduction h2o undergoes reduction so why because here copper in this in ch4 carbon is a carbon is minus 4 oxidation state here it comes in product side here it is plus 2 oxidation state here to here what happens it is going to be undergoes oxidation so that is why here in ch4 carbon here ch4 is going to be undergoes oxidation and whereas water molecules undergoes reduction so secondary in secondary reaction here agno3 is undergoes reduction agno3 undergoes reduction and here copper undergoes oxidation copper undergoes oxidation here copper is plus 0 oxidation state from here to here what happens here oxidation state increases by 2 units in cuno3 twice the oxidation state of copper is plus 2 so that is why…
