• what is carbon dioxide?

$\huge\mathfrak\pink{Answer \: ✔}$

• 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

$\huge\mathfrak\purple{Lewis \: structure}$

• The CO2 Lewis structure has two double bonds going from carbon to the oxygen atoms. According to the octet rule, each oxygen atom needs to bond twice and the carbon atom needs to bond four times.

$\huge\mathfrak\purple{Molecular \: Geometry}$

• The initial VSEPR shape for the CO2 molecule is Tetrahedral. For each multiple bond (double/triple bond), subtract one electron from the final total. The CO2 molecule has 2 double bonds so minus 2 electrons from the final total.

$\huge\mathfrak\purple{Density}$

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).
