Answer:
0.47V
Explanation:
2 Al(s) + 3 Mn2+(aq) → 2 Al3+(aq) + 3 Mn(s)
n= 6 ( six moles of electrons were transferred)
Q= [Red]/[Ox] but [Red]= 1.5M, [Ox] = 0.12 M
Q= 1.5/0.12= 12.5
From Nernst equation:
E= E°cell- 0.0592/n log Q
E°cell= 0.48 V
E= 0.48 - 0.0592/6 log (12.5)
E= 0.47V
Answer:
The amount of sodium in this sample = 32.4 grams
Explanation:
Mass of Sodium = 23 g/mol
Mass of Chlorine = 35.5 g/mol
Mass of NaCl = 35.5 g/mol
Fraction of Na in NaCl = 
=0.648
We are given a sample of 50 grams of sodium chloride.
The amount of sodium in this sample = 
The amount of sodium in this sample = 
The amount of sodium in this sample = 32.4 grams
Answer: ear a prime corn-producing area to minimize transportation costs of raw materials.

Half-life is the time required for the amount of something to fall to half its initial value. This term is usually used in nuclear physics to describe how quickly unstable atoms undergo decay, or how long stable atoms survive, radioactive decay, and it is also used more generally of any type of exponential or non-exponential decay.
In simpler terms: this is when an isotopes radioactivity is cut in half
