Answer 2

Gases lighter than air:

The gases that are lighter than air are:

A. Sulfur (IV) oxide and sulfur (VI) oxide Sulfur (IV) oxide (SO2) and sulfur (VI) oxide (SO3) are both heavier than air. They have a higher density than air and therefore do not rise or float in the atmosphere. [[1]]

B. Ozone (O3) and fluorine Ozone (O3) is heavier than air and does not rise or float in the atmosphere. Fluorine (F2) is also heavier than air. Both of these gases have a higher density than air, so they do not exhibit the property of being lighter than air. [[2]]

C. Nitrogen (IV) oxide and carbon (II) oxide Nitrogen (IV) oxide (NO2) and carbon (II) oxide (CO) are both heavier than air. They have a higher density than air and do not rise or float in the atmosphere. [[3]]

D. Neon and nitrogen (IV) oxide Neon (Ne) is lighter than air and can rise or float in the atmosphere. Nitrogen (IV) oxide (NO2) is heavier than air and does not exhibit the property of being lighter than air. [[4]]

E. Chlorine and oxygen Chlorine (Cl2) is heavier than air and does not rise or float in the atmosphere. Oxygen (O2) is also heavier than air. Both of these gases have a higher density than air, so they do not exhibit the property of being lighter than air. [[5]]

Based on the information provided, the correct answer is D. Neon and nitrogen (IV) oxide. Neon is lighter than air and can rise or float in the atmosphere, while nitrogen (IV) oxide is heavier than air and does not exhibit the property of being lighter than air.
