Over the course of two years the top layer of soil at a Michigan farm is blown away
Colt1911 [192]

For each of the situations below, state whether it describes erosion, weathering, or possibly both.

Answer:

Erosion

Explanation:

The blowing away of the top layer of the soil at a Michigan farm is best described as scenario that shows wind erosion.

Erosion is the removal of the top layer of the earth on which plant grows. In short is the washing away of soil by stream or blowing away by wind.

When soil is blow away, it is a pure case of erosion. The process of erosion usually follows weathering or sometime occurs together with it.

Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.

Often times, the process of weathering and erosion occurs together. It is loose weathering products that are carried away during erosion.

In the soil layer at Michigan, the process of erosion by wind is current taking place by ablation.

A naturally occurring oil co-distills with water to produce an oil/water distillate that is 20% oil by weight. If the molecular
Gelneren [198K]

Answer:

Explanation:

Partial pressure of oil = mole fraction of oil x total pressure

mole fraction of oil = mole of oil / mole of water + mole of oil

= mole of oil = mass of oil / molecular weight of oil

= 20 / 100 = .2

mole of water = 80 / 18

= 4.444

mole fraction of oil =  .2 / .2 + 4.444

= .2 / 4.644

Partial pressure of oil = mole fraction of oil x total pressure

= (.2 / 4.644 ) x 760 mm

= 32.73 mm Hg .
