Molecules and Structures Quick Check 1 of 41 of 4 Items 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 carbon atoms carbon atoms oxygen atoms oxygen atoms hydrogen atoms hydrogen atoms bonds between atoms
The two black balls in the model represent carbon atoms.
The black balls in the model of ethanol represent carbon atoms.
To determine what the black balls in the model represent, we need to understand the composition of ethanol. Ethanol consists of two carbon atoms, six hydrogen atoms, and one oxygen atom.
In the ball-and-stick model, each ball represents an atom, and each stick represents a bond between atoms. Since the black balls are not specified, we can conclude that the black balls in the model represent the carbon atoms in ethanol.
Therefore, the correct answer is: The black balls in the model represent carbon atoms.
