hydrogen atoms

Answer 1

The black balls in the model represent carbon atoms.

Answer 2

what is the answer

Answer 3

The answer is carbon atoms.

Answer 4

The black balls in the model represent carbon atoms.

Answer 5

The black balls in the ball-and-stick model of a molecule of ethanol represent carbon atoms. In order to determine this, we need to understand the composition of ethanol. Ethanol has two carbon atoms, six hydrogen atoms, and one oxygen atom. The model includes one red ball to represent the oxygen atom, six white balls to represent the hydrogen atoms, and eight sticks to represent the bonds between atoms. Since ethanol has two carbon atoms, there are two black balls in the model, which means the black balls represent the carbon atoms.
