The microscopic pictures i, iii, iv, v, and vi are associated with the descriptions a, d, a, c, and b, respectively. Picture ii does not match with the given options.
To associate each description with the pictures we need to remember that:
- Gas is a state in which atoms or molecules move freely around. The gases tend to expand to occupy all the space of the container.
- A solid is a state in which the atoms or molecules are very close to each other and cannot move freely, so they will not tend to occupy all the space as the gases do.
Now, let's evaluate each description.
Picture i
In this image, we can see the movement of diatomic gases (or gaseous compounds) composed of the same element. An example of this can be nitrogen gas (N₂), oxygen gas (O₂), hydrogen gas (H₂), and others.
So, this is related to option a: a gaseous compound.
Picture ii
In this, we can see a mixture of gaseous compounds composed of different elements, denoted by different colors (blue and orange). An example can be the mixture of monoxide carbide (CO) with nitrogen (N₂).
Hence, this is associated with a mixture of two gaseous compounds. There is no option related to this image.
Picture iii
In the image, we can see a mixture of monoatomic and diatomic gases. The diatomic gases are composed of two different elements (blue and orange colors).
Therefore, this is related to option d: a mixture of gaseous elements and gaseous compounds.
Picture iv
This image is similar to picture i, but in this, the gaseous compounds are composed of two different elements.
Hence, this description is related to option a: a gaseous compound.
Picture v
In this, we can see that the atoms are close to each other, which corresponds to a solid-state.
Then, this is related to option c: a solid element.
Picture vi
We can see the presence of a mixture of two gaseous elements (both monoatomics), because of the two different colors.
So, this is related to option b: a mixture of two gaseous elements.
Therefore, the descriptions of the pictures i, iii, iv, v, and vi are related to options a, d, a, c, and b, respectively. Picture ii does not match with the given options.
