Explain, why `CO_2` is a gas but `SiO_2` is a solid.

CO_(2) is a gas while SiO_(2) is a solid. Explain.

Assertion (A) : Both CO_2 snd SiO_2 have same structure . Reason (R) : CO_2 is a gas , whereas SiO_2 is a solid .

At room temperature, CO_(2) is a gas while SiO_(2) is a solid because

At room temperature, CO_(2) is a gas while SiO_(2) is a solid because

At room temperature, CO_(2) is a gas while SiO_(2) is a solid because

Explain the following (a) CO_(2) is a gas whereas SiO_(2) is a solid (b) Silicon forms SiF_(6)^(2-) ion whereas corresponding fluoro compound of carbon is not known.

is it true that CO2 is a gas whereas SiO2 is a solid.

Explain why HCl is a gas and HF is a liquid ?

Assertion (A) : CO_2 is a gas but SiO_2 had a three -dimenstional network structurte . Reason (R): CO_2 bonds and SiO_2 has a three-dimensional network structure .

Silicon is the second most abundant element (~27.2%) in the earth's after oxygen (45.5 %) Carbon. Silicon, germanium, tin and lead constitute the group 14 of the periodic table. Chemistry of silicon is distinctly different from that of carbon. For example, under standard conditions CO_(2) is a gas whereas SiO_(2) is a covalent solid. Draw the structures of CO_(2) and SiO_(2)
