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.
I don’t know but I think it would be products... that’s the best I can give. I’ll look more into it
Answer:
180.845 mol
Explanation:
Molar mass of Ca: 40,078 g/mol
Molar mass of C: 12,0107 g/mol
Molar mass of O: 15,999 g/mol
Molar mass of CaCO3: (40,078+12,0107+3×15,999) 100,0857 g/mol
The number of moles= mass of bag in g ÷ molar mass of CaCO3
⇒ n= (18.1×1000)÷100,0857 = 180.845 mol
