Best ResponseYou've already chosen the best response.0\[CuS + NO _{3}^{} > Cu ^{2+}+ \S _{8}+NO\]

Best ResponseYou've already chosen the best response.0sry thats S8 in the product side

Best ResponseYou've already chosen the best response.0re u sure equation i correct as if u see in the reaction O is not balanced first try to balance it

King

Best ResponseYou've already chosen the best response.0no my sir said that fr O we should balance using H20 and then add H+ ion to reactant side to balance H...oh yeah this is a acid base reaction

Best ResponseYou've already chosen the best response.0hey is thiss redox reaction? right in which medium u have to do balancing?

heena

Best ResponseYou've already chosen the best response.0i mean acidic medium or basic medium u are provided this info?

Best ResponseYou've already chosen the best response.0ok so first write down half oxidation and half reduction reaction if u are having problem in this step say ok i ll help u

Best ResponseYou've already chosen the best response.0i dont understand hw to do this prob.if u could explain i could try the remaining..as fr the prob i know that Copper loses 2 e and i am not sure if Nitrogen loses 1 e or gains 5 e bcuz N oxidation state is +5 in reactant side

heena

Best ResponseYou've already chosen the best response.0u know NO3 here it charge is +5 and in product ide NO its charge is 2 means from being +5 to 2 is reduction right means its half reduction reaction

Best ResponseYou've already chosen the best response.0rry actauly O have 2 charge always wid it ok its not evrytime gonna shown u

King

Best ResponseYou've already chosen the best response.0wat abt remaining can u do this 1 fr me wid steps so i can apply and do fr my other 2

King

Best ResponseYou've already chosen the best response.0and in NO N charge is +2 not 2 so its oxidation

heena

Best ResponseYou've already chosen the best response.0ok now see half reduction reaction half oxidation reaction NO3 > NO CuSS8 +5 > +2 2>0 [charge]

heena

Best ResponseYou've already chosen the best response.0now we will balance NO3 > NO H+ + NO3 > NO + H2O ( by adding water balance this equation)

Best ResponseYou've already chosen the best response.0\[Cr _{2}O _{7^{2}}+I ^{} >Cr ^{3+}+I _{2}\]

King

Best ResponseYou've already chosen the best response.0i multiply I by 2 in reactant side,and Cr by 2 in product side first

heena

Best ResponseYou've already chosen the best response.0first u say den i ll solve

King

Best ResponseYou've already chosen the best response.0then i find that Cr undergoes reduction by gaining 3 e as it is +6>+3 and I undergoes oxidation by losing 2 e +2>0

King

Best ResponseYou've already chosen the best response.0so i cross multiply and get 28H+ + 2Cr2O7 + 6I >4Cr3+ +3I2 + 14H20

King

Best ResponseYou've already chosen the best response.0but charges are not balanced so what to do?

heena

Best ResponseYou've already chosen the best response.0i m gettin 14H+ + cr2o72> 2Cr3+ + 7/2H2O + 15e

King

Best ResponseYou've already chosen the best response.0if u put 7/2 H20 then masses are not balanced

King

Best ResponseYou've already chosen the best response.0and in ure equation charges are not balanced

heena

Best ResponseYou've already chosen the best response.0wen u do blcing in equtaion masses dont make any effect ok only mole volume dey do so

King

Best ResponseYou've already chosen the best response.0no but my sir wants masses and chrges both balanced

heena

Best ResponseYou've already chosen the best response.0iabove eqn is wrong 7H+ + cr2o72> 2Cr3+ + 7/2H2O + 8e +5 5 the only prob is sigm is different in charge :(

Best ResponseYou've already chosen the best response.2Eh... It's based on change in oxidation number..

heena

Best ResponseYou've already chosen the best response.0but the way d way i m doing here wats troubling here @callistion can u guide?

Callisto

Best ResponseYou've already chosen the best response.2+6, 1, +3, 0 are oxidation numbers.. and one marked with pencil is the change
