Answer:
CO
Explanation:
Henry's law constant reflects the solubility of a gas in water. The larger the kH, the more soluble is the gas. There is a rule that states that "like dissolves like", meaning polar is soluble in polar and nonpolar is soluble in nonpolar. Since water is polar, we have to consider the nature of these gases.
<em>Xe</em> nonpolar
<em>Cl₂</em> nonpolar
<em>CO</em> polar
<em>CO₂</em> nonpolar
<em>CH₃CH₃</em> nonpolar
CO is the only polar gas, so it has the largest kH.

Answer: A.
fossil
B.
rock layer
Explanation:
Relative aging or dating can be define as the technique for determination of the age of the rock and fossil. It is a method of determining the chronological order of the past events by comparing the stratigraphic column of rocks and sediments with each other. This method can only give relative age of one object in comparison with the other but does not give the absolute date.
We are going to use Avogadro's constant to calculate how many molecules of
carbons dioxide exist in lungs:
when 1 mole of CO2 has 6.02 x 10^23 molecules, so how many molecules in
CO2 when the number of moles is 5 x 10^-2
number of molecules = moles of CO2 * Avogadro's number
= 5 x 10^-2 * 6.02 x 10^23
= 3 x 10^22 molecules
∴ There are 3 x 10^22 molecules in CO2 exist in lungs
