Which is a compound?
Think it through first, then pick an option.
- a Iron
- b Silver
- c Wax
- d Sulfur
Answer and explanation
Correct answer: c Wax
Wax is made of carbon and hydrogen; breaking it gives more than one element, so the board key calls it a compound. It is the only one of the four.
Why the other options are wrong
- a Iron: Iron is an element: breaking it gives nothing but iron, so it is not a compound.
- b Silver: Silver is an element, so it is not a compound.
- d Sulfur: Sulfur is an element, so it is not a compound.
