Question

select the correct answer from each drop - down menu.
the chemical formula for naphthalene is $c_{10}h_8$. its used to make mothballs and pesticides.
in $4c_{10}h_8$, the coefficient is , the subscript of carbon is , and the subscript of hydrogen is .

Explanation:

Step1: Identify the coefficient

The coefficient is the number before the chemical formula. For $4\text{C}_{10}\text{H}_{8}$, this is 4.

Step2: Identify carbon's subscript

The subscript for carbon is the small number after $\text{C}$ in the formula. This is 10.

Step3: Identify hydrogen's subscript

The subscript for hydrogen is the small number after $\text{H}$ in the formula. This is 8.

Answer:

Coefficient: 4, Subscript of carbon: 10, Subscript of hydrogen: 8
