Let's analyze the chemical formula for naphthalene, which is [tex]\( C_{10}H_8 \)[/tex].
In this formula:
- The subscript of carbon (C) is 10.
- The subscript of hydrogen (H) is 8.
When looking at the compound [tex]\( 4C_{10}H_8 \)[/tex]:
- The coefficient is 4, indicating that there are 4 molecules of [tex]\( C_{10}H_8 \)[/tex].
So, for [tex]\( 4C_{10}H_8 \)[/tex]:
- The coefficient is 4.
- The subscript of carbon is 10.
- The subscript of hydrogen is 8.
Therefore, the correct answers are:
- The coefficient is [tex]\(\boxed{4}\)[/tex].
- The subscript of carbon is [tex]\(\boxed{10}\)[/tex].
- The subscript of hydrogen is [tex]\(\boxed{8}\)[/tex].
