What are the properties of a liquid quizlet?
What are the properties of a liquid? Liquids take on the shape of their containers, they are fluid and they have a definite volume. What are the properties of a gas? Gases have no fixed volume of their own, the volume is determined by its container and they are fluid.
What are some properties of solids?
1) A solid has a definite shape and volume. 2) Solids in general have higher density. 3) In solids, intermolecular forces are strong. 4) Diffusion of a solid into another solid is extremely slow.
How can a gas at room temperature become a solid?
Compounds that are gases under normal atmospheric pressure at room temperature will become solid when put under high pressure. You would not be able to make liquid nitrogen at room temperature, because room temperature is way higher than its critical temperature.
How can oxygen become a solid?
Solid oxygen forms at normal atmospheric pressure at a temperature below 54.36 K (−218.79 °C, −361.82 °F). Solid oxygen O2, like liquid oxygen, is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum.
Why does oxygen exist as a gas at room temperature?
Oxygen , due to its small size is capable of forming π bond and hence exist as O=O. i.e. O2 molecule. O2 molecules are hend together by weak van der Waals forces of attaction, hence oxygen exists as a gas.
Why is oxygen inert at room temperature?
O2 is inert at room temperatures Its valency is -2. The structure of oxygen is : oxygen atom is bonded with other atom with double bond . The bond is so strong, that it can’t be easily broken and that energy is not available at room temperature .
Why Dioxygen is a gas and Sulphur is a solid?
The inter-molecular forces are weak vander waals forces. Hence, oxygen is a gas. Thus, each molecule contains 8S atoms linked by S−S bonds. Thus, S atoms are strongly held and sulphur is a solid.
Why oxygen is O2 and Sulphur is S8?
Oxygen molecule has the formula O2 while sulphur is S8. In the molecule of oxygen, the two oxygen atoms are linked to each other by double bond (O=O) i.e., one sigma bond formed by axial overlap and one pi-bond formed as a result of sidewise overlap. Therefore, oxygen exists as a diatomic molecule.
Why Sulphur is written as S8?
Oxygen will form O2, with a double bond between the O atoms. So, elemental sulfur prefers to assemble itself into S8 rings with only single bonds between the S atoms. This is also related to the reason why CO2 is a gas (two C=O. bonds, leading to discrete molecules) and SiO2 is a solid (a network of Si-O single bonds).
Is Sulfur always S8?
Sulphur exists as s3 and s8 and s7,s6.. trisulphur is not ring structure,some sort of ozone like,so unstable at room temparature. S8 is most abundant allotropes of sulphur,why?
How is O2 paramagnetic?
It shows that all the electrons in oxygen are paired, so oxygen should be diamagnetic. The last two electrons go into separate, degenerate π orbitals, according to Hund’s Rule. Thus, oxygen has two unpaired electrons and is paramagnetic.
Is O2 a paramagnetic?
As molecules containing unpaired electrons are strongly attracted by magnetic field, hence oxygen has paramagnetic nature.
Which is paramagnetic O2 or N2?
O2 is paramagnetic because it has two unpaired electrons. Thus, oxygen has two unpaired electrons and is paramagnetic. In N2 molecule, all electrons are paired. That means half of the electrons spin clockwise and half of the electrons spin anticlockwise.
Is O2 2+ paramagnetic or diamagnetic?
Because the O2 molecule has two unpaired electrons, it is paramagnetic.
Which of the following is paramagnetic o2?
Explanation: CN- , CO and NO+ are isoelectronic with 14 electrons each and there is no unpaired electrons in the MO configuration of these species. So these are diamagnetic. O-2 is paramagnetic due to the presence of one unpaired electron.
IS NO+ diamagnetic?
In NO+ , due to loss of 1 electron, the no. of unbonded electrons becomes even. Therefore, all subshells must be completely filled. Therefore, it is diamagnetic.
Which is more stable o2 or o2+ or o2?
1 Answer. O2+ is more stable than O2-. Because According to molecular orbital theory O2+ has 15 electrons &it has one electron in antibonding orbital. In the case of O2- 17 electrons are present &3 electrons are present in antibonding orbitals.
