Answer:
Based on Pauling Scale, electro negativity of Cl = 3.2, Na = 0.9 and H = 2.1
Explanation:
Thus, Electronegativity difference in Cl2 = 3.2 -3.2 = 0
Electronegativity difference in NaCl = 3.2-0.9 = 2.3
Similarly, Electronegativity difference in HCl = 3.2 - 2.1 = 1.1
Thus, among the listed molecules following is the decreasing order of electronegativity difference: NaCl> HCl > Cl2
Recent data show that phenotypic variation categories such as skin color or facial form most often used to define race.
<h3>What is phenotypic variation?</h3>
Phenotypic variation can be defined as the difference in the observable characters or attributes (phenotypes) of each organism in a specific population such as:
Based on recent data from scientific research, phenotypic variation categories such as skin color or facial form most often used to define race.
