What is oxygen's freezing point?
oxygen's freezing point is 222.65 degrees Celsius
In a model of Earth and its layers that is determined by physical properties how might the atmosphere be classified?
In a model determined by physical properties, the atmosphere would be classified as a distinct layer surrounding the Earth composed of gases, primarily nitrogen and oxygen, held in place by gravity. It would be differentiated from the other layers based on its unique composition, density, and characteristics such as temperature and pressure.
In a model of Earth and layers that is determined by physical properties how might the atmosphere be classified?
In a model determined by physical properties, the Earth's atmosphere is classified as a layer of gases that surrounds the planet due to gravity. It is composed mainly of nitrogen and oxygen, with trace amounts of other gases. The atmosphere plays a crucial role in regulating temperature and protecting life on Earth by absorbing harmful solar radiation.
What is oxygens appearance?
it only has an appearance when it is in liquid form and then it is a light pink colour
Are chemical properties of oxygen more similar to sulfur or fluorine?
The chemical properties of oxygen are more similar to sulfur than fluorine. This is because oxygen and sulfur are both nonmetals that form similar types of compounds, such as oxides and sulfides, due to their comparable electronegativities and valence electron configurations. Fluorine, on the other hand, is a halogen with different chemical properties compared to oxygen.
Which has the lower freezing point oxygen or ethanol?
Oxygen has a lower point.
What is oxygen's freezing point?
oxygen's freezing point is 222.65 degrees Celsius
What is a chemical property hardness ability to react with oxygen color or freezing point?
Hardness is a physical property that describes the ability of a substance to resist deformation. Ability to react with oxygen is a chemical property that describes how a substance interacts with oxygen. Color is a physical property that describes the visual appearance of a substance. Freezing point is a physical property that indicates the temperature at which a substance changes from a liquid to a solid.
What is oxygen's freezing point or melting point?
The freezing or melting point of oxygen is -218.8 degrees Celsius or 54.36 Kelvin.
Why the appearance and mass of sodium changes when it reacts with oxygen?
When sodium reacts with oxygen, it forms sodium oxide. The appearance changes because sodium oxide is a different compound with different properties compared to pure sodium. The increase in mass is due to the combination of the sodium atoms with oxygen atoms to form sodium oxide molecules.
When you run an electrical current through liquid water the water molecules are split apart to form oxygen and hydrogen gas this changed what properties of the water?
The splitting of water into oxygen and hydrogen gas changes its chemical composition but does not change its physical properties. The resulting oxygen and hydrogen gases can be collected separately but the water will still retain its characteristic properties such as boiling point, freezing point, and density.
What is the freezing point of oxygen in Fahrenheit?
The freezing point of oxygen is around -361.82 degrees Fahrenheit.
How are the properties of ozone and oxygen different?
Oxygen and ozone are completely different in properties. Ozone is a pollutant on breathing, while oxygen is not.
Why oxygen has a lower freezing point then ethanol?
Oxygen has a lower freezing point than ethanol because the molecular structure of oxygen is simpler, with weaker intermolecular forces between oxygen molecules compared to the ethanol molecules. This results in oxygen being a gas at room temperature and having a lower freezing point than ethanol, which is a liquid.
Which has the lower freezing point oxygen or ethanol and why?
Oxygen has a lower freezing point than ethanol. This is because the intermolecular forces in oxygen molecules are weaker than in ethanol molecules, allowing oxygen to freeze at a lower temperature.
Can material that look the same have different chemical properties?
Yes. Nitrogen and oxygen are both colorless, odorless gases. That means they share physical properties (their appearance, or lack thereof), but they have very different chemical properties because they are in different groups of the periodic table.
Why do oxygen gas and ozone have difefrent properties?
Oxygen and ozone have different properties. It is because of their atomic structure.
