Consider the reaction represented by the space-fill models shown. Drag the correct label to each box.

Blank 1 represents the substance(s) on the left.

Blank 2 represents the arrow in the middle.

Blank 3 represents the substance(s) on the right.

Blank 1: Reactants

Blank 2: Arrow (Reaction)
Blank 3: Products

In order to provide the correct labels for each blank, I would need more information about the reaction and the corresponding space-fill models. Could you please provide additional details or the images of the space-fill models?
