Oxygen is released by thermal decomposition of potassium chlorate (potassium trioxochlorideV) using a negative catalyst manganese(IV) dioxide in total absence of any reductant.
2 KClO3(s) → 3 O2(g) + 2KCl(s)
Oxygen is formed by the fusion of hydrogen or of helium in the core of a star.
What else can I help you with?
A gas in the air formed by the addition of an oxygen atom to an oxygen molecule?
Ozone is a gas formed by the addition of an oxygen atom to an oxygen molecule (O2). Ozone plays a crucial role in the Earth's stratosphere by acting as a shield against ultraviolet radiation from the sun. However, at ground level, ozone can be a harmful air pollutant.
Why are silicon and oxygen concentrated near earth surface while iron is concentrated at the core?
Silicon and oxygen are more volatile elements that were present in the primordial materials that formed the Earth's crust. They remained near the surface as the Earth differentiated. Iron, being a denser element, sank towards the core during the Earth's formation due to its higher density compared to silicon and oxygen.
When copper is heated in oxygen the compound formed is?
When copper is heated in oxygen, the compound formed is copper oxide.
What is formed by adding a third oxygen atom to an oxygen molecule?
Adding a third oxygen atom to an oxygen molecule forms ozone (O3). Ozone can be found in the Earth's stratosphere where it plays a key role in filtering out harmful ultraviolet radiation from the sun.
What process do scientists think provided earth with an oxygen-rich atmosphere?
Scientists believe that stromatolites were responsible for providing an oxygen-rich atmosphere in precambrian times. Stromatolites are structures formed of sediment. The cyanobacteria that formed these structures were photoautotrophs that used sunlight, carbon dioxide and water to produce their food and a byproduct of oxygen.
What gas is formed by a discharge from oxygen?
Oxygen formed on earth by compound of nuclear fission of sun with helium and hydrogen.
How much oxygen was there when the earth formed?
at lest 99.9%
Why is the earth covered with water?
The earth formed and let of carbon, oxygen, and other gases. Those gases collected and formed the atmosphere. When the Earth cooled, some hydrogen and oxygen bonded to make water vapor. Soon we had lakes, then oceans, and then life.
What layer did oxygen eventually formed the protected earth from harmful rays?
The OZONE LAYER becuase is made of oxygen that why
What is eventually oxygen formed an layer that protected earth from harmful rays?
Ozone
A product formed by the process of photosynthesis that is needed for all animal life on earth is?
Oxygen
Is formed when two atoms of oxygen combined in an molecule?
O2 molecule / a non polar covalent compound is formed
What is Earth Gas?
earth gases are that naturaly formed on earth eg. oxygen and the one in are gas boilers that people pump out of the ground is methane.
Is oxygen formed in nature?
Oxygen is not formed in nature, but rather it is produced through processes such as photosynthesis by plants and cyanobacteria. These organisms use sunlight to convert carbon dioxide into oxygen as a byproduct. Oxygen can also be released through chemical reactions in the Earth's atmosphere.
Why is ozone helpful to life on earth?
Ozone is a tri oxygen molecule. It is formed in a natural process by the action of UV light on oxygen molecule.
Which of the following was not characteristics of earth before the oceans formed?
Land was not covered by water, there were no marine organisms present, and the atmosphere did not have oxygen.
How are nitrogen oxygen and argon formed?
Nitrogen, oxygen, and argon are formed through various processes in the universe. Nitrogen mostly originates from the fusion of carbon and helium in stars, while oxygen is primarily formed during the later stages of stellar evolution through nucleosynthesis processes. Argon is mainly produced through the radioactive decay of potassium-40 in rocks on Earth.
