Answer 1

To correctly describe a model of methanol (CH3OH), we can break down the molecular formula:

• C (carbon): 1 atom → 1 gray sphere
• H (hydrogen): 3 atoms → 3 white spheres
• O (oxygen): 1 atom → 1 red sphere

Putting this together, a model of methanol, CH3OH, would consist of:

• 1 gray sphere (for carbon)
• 3 white spheres (for hydrogen)
• 1 red sphere (for oxygen)

Thus, the option that correctly describes a model of methanol is:

one gray sphere, three white spheres, one red sphere.
