D. 16


Sagot :

Sure, let's analyze the compound 4CH4 step by step to determine the number of hydrogen atoms.

1. Understand the formula: The compound is written as 4CH4. This indicates we have 4 molecules of CH4.

2. Know the composition of one CH4 molecule: A single CH4 molecule consists of one carbon (C) atom and four hydrogen (H) atoms.

3. Calculate hydrogen atoms in one CH4 molecule: Each CH4 molecule contains 4 hydrogen atoms.

4. Multiply by the number of CH4 molecules: Since we have 4 CH4 molecules in the given compound, we multiply the number of hydrogen atoms in a single molecule by 4:
- 4 hydrogen atoms/molecule * 4 molecules = 16 hydrogen atoms.

So, there are 16 hydrogen atoms in the compound 4CH4.

Therefore, the correct answer is:
016
