21. It is a molecule. Since it can be broken down into smaller components, then it must be made of molecules.

22. Copper. The blue-green color comes from the copper atoms reacting with water and carbon dioxide in the air to make copper hydroxycarbonate.

24. The second bucket has the more powerful cleaner. Remember, concentration is what is important. Both buckets have the same amount of ammonia in them, but the ammonia in the second bucket is contained in a smaller volume. Thus, the second bucket is more concentrated in ammonia.

25. Rust is not attracted to a magnet because when an atom is a part of a molecule, the molecule does not take on the characteristics of the atom. Instead, the atoms in the molecule join together in such a way as to give the molecule its unique characteristics; hence, the iron in the steel of my car attracts the magnet, while the iron oxide of the rust has no such characteristic.
