Responses
An illustration shows two horizontal tape diagrams made up of equally sized rectangles. Each rectangle is labeled 16. The top tape diagram is labeled hydrogen atoms and is 2 rectangles long. The bottom tape diagram is labeled oxygen atoms and is 1 rectangle long.

To represent the ratio of two hydrogen atoms to one oxygen atom in a water molecule with a tape diagram, we need to use rectangles to represent the atoms.
The correct answer is the image that shows two horizontal tape diagrams made up of equally-sized rectangles. The top tape diagram is labeled "hydrogen atoms" and is two rectangles long. Each rectangle in the top diagram is labeled "2". The bottom tape diagram is labeled "oxygen atoms" and is one rectangle long. The rectangle in the bottom diagram is labeled "1". This represents the ratio of two hydrogen atoms to one oxygen atom.
