The soil formation basically results from the weathering of rocks.
Explanation:
<u>Weathering of rocks and the formation of soil:</u>
The soil is mainly formed from different nutrients, and minerals. As different living organisms lives inside the soil. Weathering of rocks leads to deposition of nutrients, minerals, and water molecules inside the different layers. The process takes place when the different molecules are carried from one point to the another on the surface of the planet, this results in the creation of different layers of soil over time.

Answer: Hydrogen molecules will have greatest average speed.
Explanation:
The formula for average speed is :
R = gas constant
T = temperature
M = Molecular Mass
Now putting all the values:
Thus average speed of hydrogen is 8 times the average speed of oxygen. Thus hydrogen molecules will have greatest average speed
The moles can be defined as the mass of the substance with respect to molar mass. The moles of potassium nitrate is 1 mol.
<h3>How to calculate moles of a substance?</h3>The moles of a compound can be calculated from:
The molarity can be defined as the moles of solute in a liter of solution.
The molarity can be expressed as:
The molarity of potassium nitrate solution is 2 M, and the volume is 500 mL.
The moles of potassium nitrate is given as:
The moles of potassium nitrate in 2 M, 500 mL solution are 1 mol.
