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.
Answer:
I guess covalent bond is formed
The empirical formula is N₂O₅.
The empirical formula is the <em>simplest whole-number ratio of atoms</em> in a compound.
The ratio of atoms is the same as the ratio of moles, so our job is to calculate the <em>molar ratio of N:O</em>.
I like to summarize the calculations in a table.
<u>Element</u> <u>Moles</u> <u>Ratio¹ </u> <u> ×2² </u> <u>Integers</u>³
N 1.85 1 2 2
O 4.63 2.503 5.005 5
¹To get the molar ratio, you divide each number of moles by the smallest number (1.85).
²Multiply these values by a number (2) that makes the numbers in the ratio close to integers.
³Round off the number in the ratio to integers (2 and 5).
The empirical formula is N₂O₅.
