Select the diagram that correctly illustrates a mixture of oxygen, 02, and nitrogen, N2, gases.

o= atom of one element
•=atom of a different element
•first image shoes • and o together speed apart
•second image shows only o in groups of two together
•third image shows both • and o together in groups of two
•third image shows two groups of o together and two groups of • together

The second image with only o in groups of two together would correctly illustrate a mixture of oxygen (O2) and nitrogen (N2) gases.

Are you sure explain please

I apologize for the confusion in my previous response. The correct choice would be the third image, which shows both • (representing nitrogen) and o (representing oxygen) together in groups of two. This represents a mixture of oxygen and nitrogen gases. Each group of two would represent either O2 (oxygen) or N2 (nitrogen). Thank you for pointing out the error.
