Carbon dioxide is a pure substance. A pure substance can be an element or a compound. Carbon dioxide is a pure compound, consisting of two kinds of atoms that are bonded together. An element consists of merely one kind of atom. For example, oxygen is an element.
Carbon Dioxide (CO2) is a colorless, odorless, faintly acidic-tasting, and nonflammable gas at room temperature. Solid carbon dioxide, also known by the trade name Dry Ice, sublimes (converts directly from a solid to a gas) at -78 Â°C (-109V) or above. Carbon dioxide is a molecular solid with a molecular formula CO2. The linear molecule consists of a carbon atom that is doubly bonded to two oxygen atoms, O=C=O. IMPORTANT: Although both gases are common products of combustion, DO NOT confuse non-toxic carbon dioxide with poisonous, deadly carbon monoxide.
