Explanation:
When a specie tends to lose electrons in a chemical reaction then it means oxidation has taken place. When a specie tends to gain electrons then it means reduction has taken place.
So, for the given reactions the value of are as follows.
,
,
(a) Therefore, according to the given reactions the process is reduction.
(b) Here, n = 2
So, value of is as follows.
= +146680 V
= -65620 V
(c) As per the calculated values, is the best reducing agent and is the best oxidizing agent.
Also, more positive is the value more good it acts as an oxidizing agent. Hence, it is able to favor reduction.
Therefore, will more strongly favor reduction.

Explanation:
Approximately 2 mL of Solution A (on the left) is added to a sample of Solution B (on the right) with a dropping pipet. If a precipitate forms, the resulting precipitate is suspended in the mixture. The mixture is then stirred with a glass stirring rod and the precipitate is allowed to settle for about a minute.
Solution A: 0.5 M sodium hydroxide, colorless
Solution B: 0.2 M nickel(II) nitrate, green
Precipitate: light green
Ni(NO3)2(aq) + 2 NaOH(aq) —> Ni(OH)2(s) + 2 NaNO3(aq)

Answer:
Ca is larger than the Ca2+ because Ca2+ has a greater positive charge and electrons repel the nucleus.
The answer is number 2. That releases massive amounts of radiation and by the way, that is how atomic bombs are made to detonate.
