During the first half of the 20th century, the theory of plate tectonics was developed. Evidence supporting this theory included
Makovka662 [10]

A) GPS monitoring and satellite imagery of crustal movements

Explanation:

The most recent evidence supporting the theory of plate tectonics is the use of  GPS monitoring and satellite imagery of crustal movements.

GPS denotes Global Positioning Systems.

Satellite imagery is a recent advancement in the study of moving plates.

  • The global positioning system uses the position of a system of satellites in space to delineate positions on earth.
  • It works on the principles of triangulation and this helps to fix positions of objects on the earth surface.
  • With this, the change in position of the plates can be recorded by known fixed positions of objects.
  • Satellite imagery helps to map changes in terrain with time.
  • Images can be correlated through time and the shift in terrains delineated.

A generic weak acid with formula HA has a Ka = 2.76 x 10-8. Calculate the Kb for the conjugate base of the acid.
Reika [66]

Answer:

3.62x10⁻⁷ = Kb

Explanation:

The acid equilibrium of a weak acid, HX, is:

HX + H₂O ⇄ X⁻ + H₃O⁺

Where Ka = [X⁻] [H₃O⁺] / [HX]

And basic equilibrium of the conjugate base, is:

X⁻ + H₂O ⇄ OH⁻ + HX

Where Kb = [OH⁻] [HX] / [X⁻]

To convert Ka to Kb we must use water equilibrium:

2H₂O ⇄ H₃O⁺ + OH⁻

Where Kw = 1x10⁻¹⁴ = [OH⁻] [H₃O⁺]

Thus, we can obtain:

Kw = Ka*Kb

Solving for Kb:

Kw / Ka = Kb

1x10⁻¹⁴ /  2.76x10⁻⁸ =

3.62x10⁻⁷ = Kb
