Let's break down the given chemical formula step by step:
1. The chemical formula for naphthalene is [tex]\( C_{10}H_{8} \)[/tex].
2. When we have [tex]\( 4C_{10}H_{8} \)[/tex]:
- The coefficient is the number that appears before the chemical formula. It indicates the number of naphthalene molecules we have. In this case, the coefficient is 4.
- The subscript for carbon (C) is the small number that comes immediately after the carbon symbol within the chemical formula. Here, the subscript for carbon is 10.
- The subscript for hydrogen (H) is the small number that comes immediately after the hydrogen symbol within the chemical formula. Here, the subscript for hydrogen is 8.
Thus, for the formula [tex]\( 4C_{10}H_{8} \)[/tex]:
- The coefficient is 4.
- The subscript of carbon is 10.
- The subscript of hydrogen is 8.
To summarize:
- 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].
