Carbon Dioxide is not a mixture. It is a chemical compound composed of two oxygen atoms and one carbon atom.
Neither. Carbon dioxide is a pure substance, not a mixture.
Neither. Carbon dioxide is a pure substance, not a mixture.
It is heterogeneous mixture because the carbon dioxide is not completely dissolved, and easily spotted.
No. It will be a homogeneous mixture of gases.
Air in your house is a homogeneous mixture because its components (oxygen, nitrogen, carbon dioxide, etc.) are uniformly distributed throughout the space.
CO2 is a pure substance and so is homogeneous. Hint: if it has a chemical formula then it is a pure substance.
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.
Club soda is a homogeneous mixture because its components (water, carbon dioxide, and salts) are evenly distributed throughout the solution, resulting in a uniform appearance and consistent properties.
Carbon disulfide is a pure substance, not a mixture. It is a homogeneous compound composed of carbon and sulfur atoms in a fixed ratio.
A fizzy cool drink in a closed bottle is a heterogeneous mixture because you can observe different components within the bottle like bubbles of carbon dioxide in the liquid. When poured into a glass, it appears homogeneous due to the mixing of components, but it is still technically a heterogeneous mixture at a molecular level.
homogeneous
Air, like other phases that contain only gas, is usually a homogeneous mixture. If the air contains solid particulates, such as soot, or liquid particulates, such as rain drops, the air is a heterogeneous mixture.
