Carbon disulfide is a pure substance, not a mixture. It is a homogeneous compound composed of carbon and sulfur atoms in a fixed ratio.
No. It will be a homogeneous mixture of gases.
CO2 is a pure substance and so is homogeneous. Hint: if it has a chemical formula then it is a pure substance.
Air in your house is a homogeneous mixture because its components (oxygen, nitrogen, carbon dioxide, etc.) are uniformly distributed throughout the space.

Pure substance; it is one form of pure carbon.
No, carbon mixed with sand is not a homogeneous mixture. It would be considered a heterogeneous mixture because the carbon and sand do not completely mix at a molecular level and can be visibly distinguished from each other.
Carbon disulphide will evaporate from the mixture of sulphur and carbon disulphide as it has a lower boiling point compared to sulphur.
Neither. Carbon dioxide is a pure substance, not a mixture.
Neither. Carbon dioxide is a pure substance, not a mixture.
No. It will be a homogeneous mixture of gases.
It is heterogeneous mixture because the carbon dioxide is not completely dissolved, and easily spotted.
