Question

select the correct answer from each drop-down menu. the chemical formula for naphthalene is c₁₀h₈. its used to make mothballs and pesticides. in 4c₁₀h₈, the coefficient i , the subscript of carbon is , and the subscript of hydrogen is . 1 4 8 10 reset next

Explanation:

Step1: Identify the coefficient

In a chemical formula like \( 4\text{C}_{10}\text{H}_8 \), the coefficient is the number in front of the formula unit. Here, the number before \( \text{C}_{10}\text{H}_8 \) is 4, so the coefficient is 4.

Step2: Identify the subscript of carbon

In \( \text{C}_{10}\text{H}_8 \), the subscript for carbon (C) is the number after C, which is 10.

Step3: Identify the subscript of hydrogen

In \( \text{C}_{10}\text{H}_8 \), the subscript for hydrogen (H) is the number after H, which is 8.

Answer:

The coefficient is 4, the subscript of carbon is 10, and the subscript of hydrogen is 8.
