Answer:
Explanation:
m / z = 20 , 21 , 22
m / 1 = 20 , 21 , 22
m = 20 , 21 , 22 .
ratio of isotopes = 112 : 0.21 : 11.1
Average atomic mass = (112 x 20 + .21 x 21 + 11.1 x 22) / (112 + .21 + 11.1 )
= (2240 + 4.41 + 244.2) / 123.31
= 2488.61 / 123.31
= 20.18

See explanation
Explanation:
Sublimation refers to the movement of molecules directly from solid into the vapor or gas phase while deposition refers to the movement of molecules directly from the gas phase into the solid phase. The two are opposite to each other.
Frost is formed in a situation where a substance cools to a temperature that is lower than its dew point. In this situation, the vapour is directly deposited on a surface to form a frost without passing through a liquid phase. Hence the name, deposition.
This is a standard algebraic equation.
First, multiply each side by N:
0.00102 * N = 102
Now, divide both sides by 0.00102:
N = 100000
Option C: the electrons are embedded in a positive sphere.
As we know that was a wrong model and nowadays the electrons are considered to be around the nucleus, in regions called orbitals.
According to the research, fatty acids, which are long molecules in the form of a hydrocarbon chain, are a component of lipids.
<h3>What are lipids?</h3>
They are hydrophobic and water-insoluble molecules that are formed from the esterification of alcohols with fatty acids.
Lipids are a vital part of the diet of living beings since many vitamins are assimilated in the presence of certain lipids and many fatty acids are essential for animal metabolism.
Therefore, we can conclude that according to the research, fatty acids, which are long molecules in the form of a hydrocarbon chain, are a component of lipids.
