Answer: Jose is correct because air is a mixture of gases ( both elements and compounds).
Step-by-step explanation:
An element consist of only one type of atom and a compound made up of 2 or more types of elements joined together ( by ionic or covalent bonds).
Whereas air around us is a mixture of gases (both elements and compounds) like nitrogen, oxygen, argon, and carbon dioxide, and very small amounts of other gases and water vapors
Hence, Jose is correct because air is a mixture of gases ( both elements and compounds).
