Select the correct answer from each drop-down menu.

The chemical formula for naphthalene is [tex]C _{10} H _8[/tex]. It's used to make mothballs and pesticides.
In [tex]\Delta C _{10} H _8[/tex], the coefficient is [select], the subscript of carbon is [select], and the subscript of hydrogen is [select].



Answer :

Let's break down the chemical formula for naphthalene, which is [tex]\( C_{10} H_8 \)[/tex].

1. Coefficient:
In a chemical formula, the coefficient is the number that appears before the entire molecule. If no number appears, it is implied to be 1. Hence, the coefficient in [tex]\( \Delta C_{10} H_8 \)[/tex] is 1.

2. Subscript of Carbon:
The subscript of an element in a chemical formula indicates the number of atoms of that particular element in one molecule of the compound. For carbon (C) in [tex]\( C_{10} H_8 \)[/tex], the subscript is 10.

3. Subscript of Hydrogen:
Similar to carbon, the subscript for hydrogen (H) in the formula represents the number of hydrogen atoms in one molecule of the compound. For hydrogen (H) in [tex]\( C_{10} H_8 \)[/tex], the subscript is 8.

Therefore, the complete answer is:
The coefficient is 1, the subscript of carbon is 10, and the subscript of hydrogen is 8.
