Question

Which of the following lists the correct sequence of gases, from most to least, in terms of percentage within the homosphere?

A) Oxygen, Nitrogen, Argon, Carbon Dioxide
B) Nitrogen, Oxygen, Carbon Dioxide, Argon
C) Argon, Carbon Dioxide, Oxygen, Nitrogen
D) Carbon Dioxide, Nitrogen, Oxygen, Argon

Answer 1

The correct sequence of gases, from most to least abundant in the homosphere, is Nitrogen, Oxygen, Argon, Carbon Dioxide.

Step-by-step explanation:

The correct sequence of gases, from most to least abundant in the homosphere, is Nitrogen, Oxygen, Argon, Carbon Dioxide. According to the given information, approximately 78% of the atmosphere is nitrogen, making it the most abundant gas. Oxygen is the second most abundant gas, with about 21% concentration. Argon is the third most abundant gas, with a concentration of 0.9%. Carbon dioxide is the least abundant gas in the homosphere, with a concentration of 0.03%.
