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

Thus co2 is a gas at room temperature.

Why is carbon dioxide a gas at room temperature and silicon dioxide a solid. At a very low temperatures like 80 degrees centigrade co2 can become a solid and it is called dry ice. Carbon dioxide consists of molecules in which a single carbon atom is double bonded to two oxygen atoms. Carbon dioxide is a gas at room temperature while silicon dioxide is a solid at room temperature with a melting point of 1770 c. Silicon dioxide is giant molecular.

Carbon is a non metal with a fairly small atomic radius close to that of oxygen. 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. Explain this by comparing their particles and those forces between these particles. Carbon dioxide is simple molecular.

1 educator answer silicon iv oxide has a high melting point whereas carbon dioxide is a gas. It is a small molecule and non polar with only weak bonds between the molecules. 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. As co2 is.

Explain why silicon dioxide is a solid and carbon dioxide is a gas at room temperature. At room temperature co2 has only weak dispersion intermolecular forces holding the molecules together. They have a lot of energy compared to molecules in a solid. Hence it is a gas.

Carbon dioxide is a linear structure with two double bonds between carbon and oxygen. O c o each molecule is attracted to other molecules because of what is called van der waal s forces or london forces. This is at room temperature. Then at that temperature molecules of co2 are tightly bonded together to be in solid form.
