Answer:
6.22 × 10⁻⁵
Explanation:
Step 1: Write the dissociation reaction
HC₆H₅COO ⇄ C₆H₅COO⁻ + H⁺
Step 2: Calculate the concentration of H⁺
The pH of the solution is 2.78.
pH = -log [H⁺]
[H⁺] = antilog -pH = antilog -2.78 = 1.66 × 10⁻³ M
Step 3: Calculate the molar concentration of the benzoic acid
We will use the following expression.
Ca = mass HC₆H₅COO/molar mass HC₆H₅COO × liters of solution
Ca = 0.541 g/(122.12 g/mol) × 0.100 L = 0.0443 M
Step 4: Calculate the acid dissociation constant (Ka) for benzoic acid
We will use the following expression.
Ka = [H⁺]²/Ca
Ka = (1.66 × 10⁻³)²/0.0443 = 6.22 × 10⁻⁵
Answer: The correct answer is "wind direction".
Explanation:
Coriolis effect: This is an apparent deflection of moving air or water caused by the rotation of the earth.
Currents are created by wind. Their directions are determined by Coriolis effect.
Currents are created by wind. The earth is in constant motion. It describes the rotation of the earth which steers winds and the surface current. The ocean surface currents are deflected by Coriolis effect.
The direction of the wind blows from north and south towards equator.
Therefore, the Coriolis effect influences wind direction.
