Why Is Carbon Dioxide A Gas At Room Temperature And Silicon Dioxide A Solid

Carbon dioxide is a gas at room temperature while silicon dioxide is a solid at room temperature with a melting point of 1770 c.

Why is carbon dioxide a gas at room temperature and silicon dioxide a solid.

Carbon is a non metal with a fairly small atomic radius close to that of oxygen. As co2 is. Carbon dioxide is a linear structure with two double bonds between carbon and oxygen. Thus co2 is a gas at room temperature.

Explain why silicon dioxide is a solid and carbon dioxide is a gas at room temperature. Although c and si are both group 4 elements c is much smaller than si and can form double bonds with two oxygen atoms whereas si is. Then at that temperature molecules of co2 are tightly bonded together to be in solid form. O c o each molecule is attracted to other molecules because of what is called van der waal s forces or london forces.

It is a small molecule and non polar with only weak bonds between the molecules. At a very low temperatures like 80 degrees centigrade co2 can become a solid and it is called dry ice. They have a lot of energy compared to molecules in a solid. In case of sio2 each si atom is linked with o atom with single bond thus forming a network solid with high melting point 4 6k views.

Silicon dioxide is giant molecular. At room temperature co2 has only weak dispersion intermolecular forces holding the molecules together. Carbon dioxide consists of molecules in which a single carbon atom is double bonded to two oxygen atoms. This is at room temperature.

1 educator answer silicon iv oxide has a high melting point whereas carbon dioxide is a gas. Carbon dioxide is simple molecular. In math co 2 math displayed formula. Explain this by comparing their particles and those forces between these particles.
