a. A gaseous mixture that is a homogeneous mixture of two different compounds would have molecules of both compounds randomly dispersed throughout the mixture. The molecular-level (microscopic) drawing for this would show the different molecules of the two compounds coexisting in the same space, with no visible boundaries between them.
A gaseous mixture that is a homogeneous mixture of a compound and an element would have molecules of the compound and atoms of the element randomly dispersed throughout the mixture. The molecular-level (microscopic) drawing for this would show the different molecules of the compound and atoms of the element coexisting in the same space, with no visible boundaries between them.
b. A gaseous element would have atoms of the element randomly dispersed throughout the gaseous state, with no visible boundaries between them. The molecular-level (microscopic) drawing for this would show the atoms of the element coexisting in the same space.
A liquid element would have atoms of the element in close proximity to each other, but still able to move and flow freely. The molecular-level (microscopic) drawing for this would show the atoms of the element in a relatively close-packed arrangement, but with some space between them.
A solid element would have atoms of the element in a rigid, fixed arrangement with no movement. The molecular-level (microscopic) drawing for this would show the atoms of the element in a close-packed arrangement with no space between them.
