Dry ice, or solid carbon dioxide, has the molecular formula co2. how should you classify it?
element
compound
mixture
colloid
suspension

Answer;

A compound

Explanation;

A compound is a substance formed when two or more chemical elements are chemically bonded together. In other words a compound consists of atoms or ions of two or more different elements in definite proportions joined by chemical bonds into a molecule.

- In our case; solid carbon dioxide contains three atoms, that is two oxygen atoms and one carbon atom that are chemically combined, thus it is a compound .

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
