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 oxygen atoms oxygen atoms bonds between atoms
The black balls in the model represent carbon atoms.
The black balls in the model of a molecule of ethanol represent carbon atoms.
The black balls in the ball-and-stick model of a molecule of ethanol represent carbon atoms. To determine this, you can count the number of carbon atoms in the molecule and compare it to the number of black balls in the model.
In ethanol, there are two carbon atoms. Since there are two black balls in the model, it indicates that each black ball represents a carbon atom.
Therefore, the correct answer is: The black balls in the model represent carbon atoms.
