Such properties of oxygen as its appearance and freezing point are determined by?
The appearance of oxygen is a colorless and odorless gas. Its freezing point is -218.79°C (-361.82°F). These properties are determined by the molecular structure of oxygen, which exists as diatomic molecules (O2) that have weak van der Waals forces between them.
What is oxygens appearance?
it only has an appearance when it is in liquid form and then it is a light pink colour
The appearance of what element on earth allowed life to flourish?
The appearance of oxygen in Earth's atmosphere allowed life to flourish by enabling aerobic respiration, a process that produces more energy for living organisms compared to anaerobic respiration. Oxygen also played a crucial role in the development of complex multicellular organisms.
What factor caused the appearance of oxygen?
This is generally believed to be due to the appearance of life on earth in the form of stromatolites, a type of cyanobacteria (blue-green algae). These converted carbon dioxide to oxygen by the process of photosynthesis.
Explain why the surface of sodium is only shiny when it is freshly cut?
The shiny appearance of freshly cut sodium is due to its high reactivity with oxygen in the air. When sodium is exposed to air, it quickly reacts with oxygen to form sodium oxide, which creates a dull, opaque layer on the surface of the metal. This layer of sodium oxide obscures the shiny surface of the metal, giving it a dull appearance. Therefore, only freshly cut sodium displays its characteristic shiny appearance before it reacts with oxygen in the air.
What is the appearance of the Oxygen Family?
Clear

Is oxygen lustrous?
No, oxygen is not lustrous. It is a colorless, odorless, and tasteless gas at room temperature, and it does not have a shiny or reflective appearance.
Is there a picture of what a bad oxygen sensor looks like compared to a good oxygen sensor?
The outward appearance of a defective oxygen sensor is no different than the appearance of a brand new one. The components that fail are internal and cannot be repaired ... direct replacement is the only fix.
What is oxygens appearance?
it only has an appearance when it is in liquid form and then it is a light pink colour

Scientists hypothesize that oxygen begin to accumulate in earth's atmosphere after the appearance of living with the ability to?
Photosynthesize.
What evidence points to the date of the appearance of the first oxygen-producing organisms?
iron oxides in rock
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.
What factor caused appearance of oxygen?
When it gets cold out side and someone breathes and sees their breath they are viewing oxygen. They see it do to the particles of moisture in the air and the cold verses hot air.
What does appearance of a blue or pink color in thioglycolate tube mean?
To indicate a presence of free residual oxygen.
What was the appearance of aerobic life made possible by?
The appearance of aerobic life was made possible by the evolution of oxygenic photosynthesis, which involved the conversion of sunlight and carbon dioxide into energy and oxygen. This process resulted in the accumulation of atmospheric oxygen, creating an environment suitable for aerobic organisms to thrive.
