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

In math co 2 math displayed formula.

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

At room temperature co2 has only weak dispersion intermolecular forces holding the molecules together. Carbon dioxide is simple molecular. 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.

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. Carbon dioxide is a gas at room temperature silicon iv oxide is a solid with a high. It is a small molecule and non polar with only weak bonds between the molecules. Silicon dioxide is giant molecular.

At a very low temperatures like 80 degrees centigrade co2 can become a solid and it is called dry ice. Carbon is a non metal with a fairly small atomic radius close to that of oxygen. 1 educator answer silicon iv oxide has a high melting point whereas carbon dioxide is a gas. Hence it is a gas.

This is at room temperature. As co2 is. 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.

Explain this by comparing their particles and those forces between these particles. Then at that temperature molecules of co2 are tightly bonded together to be in solid form. Carbon dioxide is a linear structure with two double bonds between carbon and oxygen. Thus co2 is a gas at room temperature.
