sci,
s,cl

Explanation:

Step1: Analyze prefixes

In naming covalent compounds, prefixes indicate the number of atoms. "Hexa -" means 6.

Step2: Determine formula

For sulfur hexachloride, "sulfur" is \(S\) (1 atom as no prefix for first element if 1) and "hexachloride" means 6 \(Cl\) atoms. So formula is \(SCl_{6}\).

Answer:

C. \(SCl_{6}\)
