Question

4cf₂cl₃, carbon, fluorine, chlorine, 4, 8, 12

Explanation:

Step1: Analyze the formula \(4CF_2Cl_3\)

The coefficient is 4, and for each \(CF_2Cl_3\) molecule, we count the number of each atom. For fluorine (F), in one \(CF_2Cl_3\) there are 2 F atoms. So we multiply the number of F atoms per molecule by the coefficient.

Step2: Calculate the number of F atoms

Number of F atoms = coefficient × number of F per \(CF_2Cl_3\) = \(4\times2 = 8\)

Answer:

8
