7.5x10^14 Hz. I just worked it out on paper.
Step by step explanation
1.First take a bottle and fill it with water
2.mark points on the bottle in any level four directions perpendicularly
3.make a hole in the points you have marked
Observation
The liquid exerts pressure equally and perpendicularly in all directions
Hope this answer helps
The correct answer is Conference committee.
Answer is: pH value of morphine is 10.64.<span>
Chemical reaction: </span>C₁₇H₁₉NO₃ + H₂O → C₁₇H₁₉NO₃H⁺ +OH⁻.<span>
Kb(</span>C₁₇H₁₉NO₃) = 10∧(-5,79) = 1,62·10⁻⁶.<span>
c(</span>C₁₇H₁₉NO₃<span>) = 0,115 M.</span><span>
Kb(</span>C₁₇H₁₉NO₃) = c(OH⁻) · c(C₁₇H₁₉NO₃H⁺) ÷ c(C₁₇H₁₉NO₃).<span>
c(OH</span>⁻)
= c(C₁₇H₁₉NO₃H⁺) = x.
1,62·10⁻⁶<span> = x² ÷
(0,115 - x).</span><span>
Solve quadratic equation: x = c(OH</span><span>⁻) = </span><span>0,000431 M.
pOH = -log(</span>0,000431 M<span>) = 3,36.
pH = 14 - 3,36 = 10,64.</span>
