Answer:
The equations are:
3Mn + 2NO3- + 8H+ -----------> 3Mn2+ + 2NO + 2H2O
2Mn2+ + 5IO4- + 3H2O ---------> 2MnO4- + 5IO3-+ 6H
Ecell = 1.6 V - 1.51 V = 0.09 V
Using the equation of Nernst ,
ΔG = -nFEcell
where n= number of electrons transferred = 10 mol
F = Farraday's constant = 96485 C/mol
Ecell = 0.09V
Now, ΔG = -10 * 96485 C/mol * 0.09 V
ΔG = -86836.5 J/mol (\because C*V =J)
ΔG = -86.84 kJ/mol
Now, Ecell = (0.0591/n)*log K
0.09 = 0.0591/10 *logK
0.09 = 0.00591 * log K
log K = 0.09 / 0.00591
log K = 15.23
K = 10-15.23
K = 5.89*10-16
Answer:Air would be considered a part of the macroscopic domain.
Explanation:
Because moisture in the air, icebergs, and the ocean represents water in the macroscopic domain.
Answer:
Endothermic. Endothermic phase changes take in heat from the surrounding environment; they include melting, sublimation and boiling. ... For example, the forces that hold iron atoms together are strong, so it takes high temperatures to melt iron.
Explanation:
