Answer: a contest in which you are eliminated if you fail to spell a word correctly.
As you go from left to right and down to up on the periodic table, atomic radius decreases. This would make helium the smallest and francium the largest.
Answer: 0.124 V
Explanation:

To calculate standard Gibbs free energy, we use the equation:

Where,
n = number of electrons transferred = 4
F = Faradays constant = 96500 C
= standard cell potential = ?
Putting values in above equation, we get:


Thus the standard potential E°, for this reaction is 0.124 V
Answer:
(C). is the answer, I think
