Question

Give two reasons to support the statement that carbon dioxide is a compound and not a mixture

Answer 1

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.

Answer 2

a compound is formed when 2 elements combine in a chemical reaction. The compound formed cannot be seperated into the constituent elements by any physical method, unlike mixtures. it doesn't show the properties of the elements combined in it (individual properties). hence as it shows all these characteristics, carbon dioxide is a compound.

I hope you find the answer useful!
