Final answer:

To arrange the gases in the mixture from highest partial pressure to lowest partial pressure, consider their relative amounts: O2, N2, CO2, He.

Step-by-step explanation:

The partial pressure of each gas in a gaseous mixture is determined by the amount of that gas present in the mixture. To arrange the gases in the mixture from highest partial pressure to lowest partial pressure, we need to consider their relative amounts. The given gases are He, O2, N2, and CO2.

First, let's look at their percentages in the atmosphere. Oxygen (O2) has the highest percentage at 20.9%, followed by nitrogen (N2) at 78.6%, carbon dioxide (CO2) at 0.04%, and helium (He) at a trace amount.

Based on their percentages, we can arrange the gases from highest to lowest partial pressure as follows: O2, N2, CO2, He.

Final answer:

The gases are arranged from highest to lowest partial pressure as follows: nitrogen (N2), oxygen (O2), helium (He), and carbon dioxide (CO2), based on typical atmospheric composition and Dalton's Law.

Step-by-step explanation:

The question asks to arrange the gases helium (He), oxygen (O2), nitrogen (N2), and carbon dioxide (CO2) in the order of highest to lowest partial pressure. The partial pressure of a gas in a mixture can be determined using Dalton's Law and atmospheric composition data. Based on the composition of air, the primary gases are nitrogen at 78.6%, oxygen at 20.9%, and carbon dioxide at 0.04%. There is no given percentage for helium, but typically it is a trace gas with a very low percentage. Therefore, using this information, we can arrange the gases from highest to lowest partial pressure as: N2, O2, He, CO2. This order assumes that He has a higher partial pressure than CO2, which is not guaranteed without specific data but is inferred based on typical atmospheric composition where trace gases would exceed the very low percentage of CO2.
