Carbon dioxide is a colorless, odorless gas found in our atmosphere. Its chemical formula is CO2, which means it is one carbon atom bonded to two oxygen atoms. CO2 is used in the carbonation of soda drinks and is found in solid form as dry ice.
Accordingly, is carbon dioxide gas liquid or solid?
Carbon dioxide is colorless. At low concentrations the gas is odorless however, at sufficiently-high concentrations, it has a sharp, acidic odor. Carbon dioxide has no liquid state at pressures below 5.1 standard atmospheres (520 kPa).
Why Carbon dioxide is a gas?
The reason why carbon dioxide is a gas and silicon dioxide is a solid is because their chemical structures are different. Carbon dioxide is a linear structure with two double bonds between carbon and oxygen. It is a small molecule and non-polar with only weak bonds between the molecules. Hence it is a gas.
