Answer:
11.76
Explanation:
Potassium hydroxide is a strong base that dissociates completely according to the following reaction.
KOH(aq) → K⁺ + OH⁻
Then, the concentration of OH⁻ will be 0.00580 M.
The pOH of the solution is:
pOH = -log [OH⁻]
pOH = -log 0.00580 = 2.24
We can calculate the pH using the following expression.
pH + pOH = 14
pH = 14 - pOH = 14 - 2.24 = 11.76
Using the titration formula, we know that:
(2.0 M)(volume of acid)=(3.0 M)(250 mL)
volume of acid = (3.0)(250)/(2.0) = 375 mL

Explanation:
As long as the plunger creates a complete seal around the toilet exit to shove or pull out the waste that is clogging the system it wouldnt matter the size as long as it fulfills its given task.
Answer:
"The higher the spring constant, the stiffer the spring. The spring constant is not the same value for different elastic objects. For a given spring and other elastic objects, the extension is directly proportional to the force applied. For example, if the force is doubled, the extension doubles."
