Cu2+SO4 2- + Zn0 gives Zn2+So42- +C0
Cu2+ +2e- gives Cu0 {reduction}
Zn0 - 2e- gives Zn2+ {oxidization}
Therefore,
Oxidizing Agent= CuSO4
Reducing Agent= Zn
As Oxidization and Reduction are taking place simultaneously 
CuSO4 +Zn gives ZnSO4 + Cu is a REDOX REACTION.]]> 2020-07-22 05:58:45 UTC https://padlet.com/subhoshree15/9DQuestion4/wish/659891812 https://padlet.com/subhoshree15/9DQuestion4/wish/659891977 Redox as Zno +co gives zn + co2 as zn loses oxygen and co gains oxygen to form co2 so as zno loses oxygen so it is reduction and co gains oxygen it is oxidation. Hence a redox reaction has taken place.
Oxidizing agent:ZnO
Reducing agent:CO]]> 2020-07-22 05:59:05 UTC https://padlet.com/subhoshree15/9DQuestion4/wish/659891977 https://padlet.com/subhoshree15/9DQuestion4/wish/659892217 Zn + 2HCl gives ZnCl2 + H2

Zn0 + 2H1+Cl- gives Zn2+Cl- + H2
Zn - 2e- gives Zn2+  Oxidation
H1+ + e- gives H20    Reduction 
Since there are oxidation and reduction reactions happening simultaneously it is a redox reaction.

Oxidising agent is zinc 
Reducing agent is Hydrochloric acid]]> 2020-07-22 05:59:32 UTC https://padlet.com/subhoshree15/9DQuestion4/wish/659892217 https://padlet.com/subhoshree15/9DQuestion4/wish/659895103 2NH3 + 3Cl2 gives N2 + 6HCl
Here, reduction is taking place as HCl is formed, which means hydrogen is added to chlorine.
Oxidation is taking place, in nitrogen as Ammonia is broken down and it forms nitrogen and hydrogen which means hydrogen is removed. 
Hence, oxidation and reduction has taken place simultaneously, a redox reaction has taken place.
Oxidizing agent: 
Reducing agent: Ammonia]]> 2020-07-22 06:04:52 UTC https://padlet.com/subhoshree15/9DQuestion4/wish/659895103 https://padlet.com/subhoshree15/9DQuestion4/wish/659896857 This is reduction of oxygen bcause sulphur is combining with oxygen, sulphur is reducing oxygen oc its fair state the balanced equation is 2so2]]> 2020-07-22 06:07:45 UTC https://padlet.com/subhoshree15/9DQuestion4/wish/659896857 https://padlet.com/subhoshree15/9DQuestion4/wish/659897043 2020-07-22 06:08:02 UTC https://padlet.com/subhoshree15/9DQuestion4/wish/659897043 https://padlet.com/subhoshree15/9DQuestion4/wish/659900621 Try writing the valency of elements by criss cross method and the valency of elements 0
Try balancing the equation]]> 2020-07-22 06:13:36 UTC https://padlet.com/subhoshree15/9DQuestion4/wish/659900621 https://padlet.com/subhoshree15/9DQuestion4/wish/659902775 Oh sry didnt see u typed thanks]]> 2020-07-22 06:17:17 UTC https://padlet.com/subhoshree15/9DQuestion4/wish/659902775
