what is carbon dioxide ????
Answers
Answer ❤️
Carbon dioxide is a colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas.

Molar mass: 44.01 g/mol
Formula: CO2
Boiling point: -78.46 °C
Triple point temperature: -56.6 °C
ChemSpider ID: 274
Soluble in: Water
Lewis structure
For Lewis structure of CO2, you will now have two Oxygen atoms forming double bonds with a Carbon atom. As all the valence electrons of all the atoms are used, there are no lone pairs of electrons or non-bonding pairs of electrons in the molecule.
Molecular geometry
linear
The molecular geometry of CO2 is linear with symmetric charge distribution about the carbon atom. Therefore CO2 is non-polar
Density
around 1.98 kg/m3
At standard temperature and pressure, the density of carbon dioxide is around 1.98 kg/m3, about 1.53 times that of air. Carbon dioxide has no liquid state at pressures below 5.1 standard atmospheres (520 kPa).
Intermolecular forces
CO has two C-O bonds. The dipoles point in opposite directions, so they cancel each other out. Thus, although CO₂ has polar bonds, it is a nonpolar molecule. Therefore, the only intermolecular forces are London dispersion forces.
