The Coriolis effect influences _____. neither wind speed nor wind direction wind speed both wind speed and wind direction wind d
Alona [7]

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.

The equilibrium constant for the dissociation of acetic acid at 25oC is 1.85x10-5. What will be the equilibrium concentration of
Gre4nikov [31]

Answer:

Equilibrium concentration of H^{+} is 1.4\times 10^{-3}M

Explanation:

Construct an ICE table to calculate changes in concentration at equilibrium.

   CH_{3}COOH\rightleftharpoons CH_{3}COO^{-}+H^{+}

I:     0.1                                                          0                     0

C:     -x                                                          +x                   +x

E:    0.1-x                                                       x                      x

\frac{[CH_{3}COO^{-}][H^{+}]}{[CH_{3}COOH]}= K_{a}(CH_{3}COOH)

(species inside third bracket represent equilibrium concentrations)

\frac{x^{2}}{0.1-x}=1.85\times 10^{-5}

or, x^{2}+(1.85\times 10^{-5})x-(1.85\times 10^{-6})=0

So, x=\frac{-(1.85\times 10^{-5})+\sqrt{(1.85\times 10^{-5})^{2}+(4\times 1.85\times 10^{-6})}}{2}M

or, x=1.4\times 10^{-3}M

So, equilibrium concentration of H^{+}=[H^{+}]=x=1.4\times 10^{-3}M
