Question

co2 ga is made up of two substances but it is not a mixture explain? why

Answer 1

In mixture the different substances are not chemically fused while in a compound the different elements making it are chemically fused. Mixtures can be separated by simple mechanisms such as handpicking, heating and filtering while elements in compounds can be separated through chemical reactions.Mixtures can varied in quantity of the constituting substances easily while in compounds you cannot vary the amount of the elements.

Substances making up a mixture maintain their individual chemical and physical properties while compounds have different chemical and physical properties from the elements that make them.

Examples of mixtures - air, beans and sand, salt water, flour and nail fillings.

Examples of compounds - Sodium chloride, carbon dioxide and water.

Carbon dioxide is a compound because:

i) It has different chemical and physical properties from the carbon and oxygen the makes it.

ii) You can only separate carbon from oxygen in carbon dioxide using a chemical reaction.

Answer 2

Carbon dioxide gas is made up of two substance but it is not a mixture because it from a new substance that is CO2 that substance is called compound so that's why carbon dioxide gas is not a mixture.
