Question

A molecule of ethanol has two carbon atoms, six hydrogen atoms, and one oxygen atom. A ball-and-stick model of a molecule of ethanol is made from the following components:

one red ball
two black balls
six white balls
eight sticks

What do the black balls in the model represent?

(1 point)
Responses

hydrogen atoms
hydrogen atoms

carbon atoms
carbon atoms

bonds between atoms
bonds between atoms

Answer 1

The black balls in the model represent carbon atoms.

Answer 2

The black balls in the model of ethanol represent carbon atoms. To determine this, we can look at the given information that states a molecule of ethanol has two carbon atoms. Since there are two black balls in the model, it can be concluded that they represent the carbon atoms. Therefore, the correct answer is "carbon atoms".
