OPTION C IS YOUR ANSWER!.
<h3>
Answer:</h3>
pH = 5
<h3>
Explanation:</h3>
<u>We are given;</u>
- Concentration of a solution HI as 0.00001 M
We are required to calculate the pH of Hydronium ions.
- When the acid dissociates in water to;
HI + H₂O → H₃O⁺(aq) + I⁻(aq)
- The concentration of H₃O⁺ ions is 0.00001 M\
- We need to know that pH = -log[H₃O⁺]
Therefore;
pH =-log 0.00001 M
= 5
Thus, the pH of the hydronium ions is 5
As we know that spring force is given by

here we know that
F = 700 N
also we know that
k = 3500 N/m
now from above equation we will have

now we will have


so here we can say that end of the spring will be compressed by 20 cm
