Answer:
A nonpolar molecule has no separation of charge
Explanation:
 
        
             
        
        
        
In order to find molarity, you must first find the number of moles that was dissolved.
Now, Moles = Mass ÷ Molar Mass
                    
⇒  Moles of NaCl  = 2.922 g ÷ 58.44 g/mol 
                       
                               = 0.05 moles
∴ the Molarity of the NaCl is 0.05 M [Option 1]
        
             
        
        
        
There is thermal energy, but temperature is also a measure of the average kinetic energy, so either of those should be acceptable answers for the question.
        
             
        
        
        
Answer:
0.3793 M
Explanation:
The unknown metal is zinc. So the equation of the reaction is;
Zn(s) + Cu^2+(aq) -------> Zn^2+(aq) + Cu(s)
From Nernst equation;
E = E° - 0.0592/n log Q
 [Cu2+] = 0.050179 M
n = 2
[Zn^2+] = ?
E = 1.074 V 
E° = 0.34 - (-0.76) = 1.1 V
Substituting values;
1.074  = 1.1 - 0.0592/2 log [Zn^2+]/0.050179
1.074 - 1.1 = - 0.0592/2 log [Zn^2+]/0.050179
-0.026 = -0.0296  log [Zn^2+]/0.050179
-0.026/-0.0296 = log [Zn^2+]/0.050179
0.8784 =log [Zn^2+]/0.050179
Antilog(0.8784) = [Zn^2+]/0.050179
7.558 =  [Zn^2+]/0.050179
 [Zn^2+] = 7.558 * 0.050179
 [Zn^2+] = 0.3793 M
