Well we had to leave our books at home and just take this test
I'm not cheating -_- I'm reviewing my answers
The answer is "compound". A compound is a substance that is made up of two or more different elements chemically bonded together. To determine if a substance is a compound, you can consider its properties and behavior. Compounds have specific chemical compositions and can only be separated into their constituent elements through chemical reactions, not through physical methods such as filtering, boiling, or sifting.
