I believe it’s A but I could be wrong
 
        
                    
             
        
        
        
 means 0.5 raise to the power of n. "To the power of" means an action of multiplication of 0.5 to n times.
 means 0.5 raise to the power of n. "To the power of" means an action of multiplication of 0.5 to n times.
The different values of n are given in the table. Substituting these values:
For A:
n = 1 (given)

For B:
n = 2 (given)

For C:
n = 3 (given)

For D:
n = 6 (given)

For E:
n = 8 (given)

Hence, the values are:
A = 0.5
B = 0.25
C = 0.125
D = 0.015625
E = 0.00390625
 
        
                    
             
        
        
        
Ku[Fe(CN)6] is potassium ferrocyanide
[Co cl2(en)2] cl is cis-dichlorobis cobalt
hope it helps
        
             
        
        
        
Yes that is definitely true
 
        
             
        
        
        
Answer:
The pH of the HCl solution is 3.9
Explanation:
Knowing the molar mass of HCl (36.5g/mol) it is possible to calculate the number of moles of HCl in the solution,
 of HCl
 of HCl
HCl is a strong acid and when added to water will form H+ and Cl-, thus the moles of HCl are equal to moles of H+ in 354 mL of water

The concentration of protons in the solutions is  .
.
The expression used to calculate the pH is
![pH = -Log ([H^{+}]) = -Log (1.16x10^{-4} M) = 3.9](https://tex.z-dn.net/?f=pH%20%3D%20-Log%20%28%5BH%5E%7B%2B%7D%5D%29%20%3D%20-Log%20%281.16x10%5E%7B-4%7D%20M%29%20%3D%203.9)
Hence, the pH of the HCl solution is 3.9 and Pepsi has a pH of 3.4 approximately, so they have almost the same pH.
