Verified step by step guidance1
Identify the chemical formula given: SO_3.
Determine the elements present: S is sulfur, and O is oxygen.
Recognize that the compound consists of sulfur and oxygen only, so it is a molecular (covalent) compound, not involving silver (Ag).
Recall the naming rules for molecular compounds: use prefixes to indicate the number of atoms and name the first element followed by the second element with an '-ide' suffix.
Apply the rules: 'S' is sulfur, 'O_3' means three oxygen atoms, so the correct name is 'sulfur trioxide'.
