because the atoms are chemically joined and you cannot use the physical methods eg) evaporatoion, distillation, etc. to separate them
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.
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.
No, carbon dioxide is not a mixture. It is a compound composed of one carbon atom and two oxygen atoms. It is a pure substance.
Carbon dioxide is a compound. It is made up of the elements carbon and oxygen in a 1:2 ratio. It is a covalent compound that has simple molecular structure.
