Answer 1

To find the correct description of a model of methanol (CH₃OH), we should break down the molecular formula.

• Methanol consists of:
  • 1 carbon atom (C)
  • 4 hydrogen atoms (H)
  • 1 oxygen atom (O)

Now let's correlate this with the color codes provided:

• Carbon (C) is represented by a gray sphere.
• Hydrogen (H) is represented by a white sphere.
• Oxygen (O) is represented by a red sphere.

Putting it all together, a methanol molecule will have:

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

Therefore, the correct description of a model of methanol, CH₃OH, is:

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