A ball-and-stick model of a molecule of formaldehyde, CH2O, is made from the following components: one black ball, one red ball, two white balls, and three sticks. What do the sticks represent? A. oxygen atoms. B. carbon atoms. C. bonds between atoms. D. hydrogen atoms.

The sticks in a ball-and-stick model represent C. bonds between atoms. They illustrate how atoms are connected in the molecule. In the case of formaldehyde (CH2O), the sticks represent the covalent bonds between the carbon, hydrogen, and oxygen atoms.
