It is heterogeneous mixture because the carbon dioxide is not completely dissolved, and easily spotted.
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.
