one gray sphere, four white spheres, one red sphere

Answer 1

To describe a model of methanol (CH3OH), we need to break down its molecular formula:

• C (Carbon) = 1 atom
• H (Hydrogen) = 3 atoms
• O (Oxygen) = 1 atom

Using the colors from the table provided:

• Carbon (C) = gray
• Hydrogen (H) = white
• Oxygen (O) = red

Now, assembling these components together, we have:

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

So, the correct option that describes a model of methanol, CH3OH, is:

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

This matches the description given above, hence the answer is:

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