I believe it’s c for warm front then f for cold front. I hope that helps!
amount of CaO that would be produced when 35.5g of CaCO3 decompose on heating (Ca= 40, O = 16, C = 12, H = 1
just put the values to have answer
At anode,
Cd-----> + 2
At cathode,
+ 2e -----> Ni
Overall reaction,
+ Cd(s) ------> + Ni K=1.17
(aq) (aq) (s)
By nernst equation,
E= - Log K
Where,
F=96500c/mol
M=2
T=298K
E=Zero at equilibrium
R=8.314 J
0= - Log(1.17)
= 0.150v
what is nernst equation?
The Nernst equation is a chemical thermodynamical relationship used in electrochemistry that enables the determination of a reaction's reduction potential (half-cell or full-cell reaction) from the standard electrode potential, absolute temperature, the number of electrons involved in the oxydo-reduction reaction, and activities (often approximated by concentrations) of the chemical species undergoing reduction and oxidation, respectively. It was given the equation's original name in honor of the German physical scientist Walther Nernst.
The link between cell potential, standard potential, and the behaviors of electrically active (electroactive) species is described by the Nernst equation. It links the standard cell potential to the effective concentrations (activities) of the reaction's constituent parts.
