Carbon dioxide (CO2) is a chemical compound. A molecule of it is composed of a lone carbon atom and two oxygen atoms, each connected to the carbon atom by a covalent bond. A link can be found below to the relevant Wikipedia post on this significant atmospheric gas.
Element: oxygen, potassium Compound: sodium chloride, potassium dichromate Mixture: air, orange juice
A.) compound
Sand is a mixture of silicon dioxide and small amounts of other minerals, but silicon dioxide itself is a compound made of silicon and oxygen atoms. Carbon dioxide, on the other hand, is a separate compound made of carbon and oxygen atoms.
Silicon dioxide is a compound, not an atom, element, or mixture. It is composed of silicon and oxygen atoms bonded together in a specific ratio to form a single chemical substance.
Obsidian is a naturally occurring volcanic glass composed primarily of silicon dioxide, which is a compound made up of the elements silicon and oxygen. Therefore, obsidian is not an element but a mixture of elements in compound form.
