Suffix with sulf-
Answer:
-IDE
Hint:
Think of the ending used in chemistry for binary compounds, like what you’d find in sodium chloride or hydrogen sulfide.
Explanation:
The clue asks for a suffix that follows "sulf-" to form a complete word. In chemistry, "sulfide" is a common term where "-ide" is added to "sulf-" to name compounds like hydrogen sulfide. The answer is simply the suffix itself, "-ide," which appears in many chemical names for binary compounds. Think of it as the ending that turns "sulf-" into a recognizable scientific term.
