Question

state the physical and chemical properties of carbon diaxide

Answer 1

Explanation:

Physical properties

Carbon dioxide is colorless. At low concentrations the gas is odorless; however, at sufficiently-high concentrations, it has a sharp, acidic odor. At standard temperature and pressure, the density of carbon dioxide is around 1.98 kg/m3, about 1.53 times that of air.

chemical properties -

At room temperatures (20-25 oC), carbon dioxide is an odourless, colourless gas, which is faintly acidic and non-flammable. Carbon dioxide is a molecule with the molecular formula CO2. The linear molecule consists of a carbon atom that is doubly bonded to two oxygen atoms, O=C=O.

Water solubility: 0.9 vol/vol at 20 oC

Concentration in air: 370,3 * 107 ppm

Solid: Temperature < -78 oC
