Oxidation:- it loses electrons
Reduction:- it gains electrons
Answer:
6.1×10^8
Explanation:
The reaction is;
Sn^2+(aq) + Cd(s) -----> Sn(s) + Cd^2+(aq)
E°cell = E°cathode - E°anode
E°cathode= -0.14 V
E°anode= -0.40 V
E°cell = -0.14-(-0.40)
E°cell= -0.14+0.40
E°cell= 0.26 V
But
E°cell= 0.0592/n log K
E°cell= 0.0592/2 log K
0.26= 0.0296log K
log K = 0.26/0.0296
log K= 8.7838
K= Antilog (8.7838)
K= 6.1×10^8
Very little electric force is required to cause electron flow in conductors. This is due to electrons called "free electrons", which exist in the atoms of conductors. "Free electrons" are electrons that are very weakly bonded to the atom. ... Metals such as copper, silver, and gold are good conductors.
Well, atoms are loosely bound and free to move through the material. Almost all, or just most, atoms will hold on to electrons very tightly and are insulators.
Answer:
The balanced half reaction in an acidic medium is :
Explanation:
While balancing the half-reaction in an acidic medium, we will first balance oxygen atoms by adding water:
1) Adding 1 water molecule on product side to balance oxygen atoms.
Now balance hydrogen atom by adding 
.
2) Adding 2 hydrogen ions on reactant side to balance hydrogen atoms.
Now balance the charge adding electrons on the side where positive charge is mor.
3) Adding 1 electrons on reactant side to balance charge of the overall reaction:
The balanced half reaction in an acidic medium is :
Answer:
1) Heat
Explanation:
Heat Transfer: The movement of heat from a warmer object to a colder one
