sry thats S8 in the product side

re u sure equation i correct as if u see in the reaction O is not balanced first try to balance it
 2 years ago

KingBest ResponseYou've already chosen the best response.0
no 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

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

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

ok so first write down half oxidation and half reduction reaction if u are having problem in this step say ok i ll help u

KingBest ResponseYou've already chosen the best response.0
i 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
 2 years ago

heenaBest ResponseYou've already chosen the best response.0
u 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

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

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

and in NO N charge is +2 not 2 so its oxidation

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

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

ok luk at this prob i noted down oxidation and reduction reactions but still its coming wrong

\[Cr _{2}O _{7^{2}}+I ^{} >Cr ^{3+}+I _{2}\]
 2 years ago

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

heenaBest ResponseYou've already chosen the best response.0
first u say den i ll solve
 2 years ago

KingBest ResponseYou've already chosen the best response.0
then 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

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

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

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

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

and in ure equation charges are not balanced

wen u do blcing in equtaion masses dont make any effect ok only mole volume dey do so
 2 years ago

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

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

ok u done this with ion electron method

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

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

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

heenaBest ResponseYou've already chosen the best response.0
yea i get that thing wat u done but i m thig wat i have done wrong here (:
