CO2 is a pure substance and so is homogeneous. Hint: if it has a chemical formula then it is a pure substance.
Diamond is formed from carbon with some inclusion of trace minerals, for colour.
This yield is very low - 13 %.
Carbon disulfide is the chemical compound made up of linear S=C=S molecules
Carbon disulfide has many industrial applications. Frequently used in fumigation and also as an insecticide, carbon disulfide is not used in the dry cleaning industry.
homogeneous
Homogeneous because you can't see the carbon in the sand.
homogeneous
Neither. Carbon dioxide is a pure substance, not a mixture.

Carbon disulfide is CS2
heterogeneous
No
It is heterogeneous mixture because the carbon dioxide is not completely dissolved, and easily spotted.
carbon disulfide
CS2 stands for carbon disulfide; the 2 is written as a subscript and stands for a chemical compound which contains a carbon atom and two sulfur atoms.
