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 bonds between atoms Skip to navigation

Answer 1

In the ball-and-stick model of a molecule of ethanol, the black balls represent carbon atoms. Therefore, the correct answer is:

carbon atoms

Answer 2

Use the model of a molecule to answer the question. H H | | H — C — C — O — H | | H H How many atoms of carbon does this molecule have? (1 point) Responses 2 atoms 2 atoms 6 atoms 6 atoms 4 atoms 4 atoms 1 atom 1 atom Skip to navigation

Answer 3

In the given model of the molecule, there are 2 carbon atoms indicated by the two "C" symbols in the structure.

Therefore, the correct answer is:

2 atoms
