What is the oxidation number of an elementary substance?
The oxidation number of an elementary substance is zero because there is no transfer of electrons between atoms of the same element in a compound. Each atom in an elementary substance is considered to have an oxidation number of zero.
Is ozone a mixture?
Ozone is a molecule, neither a solution nor a mixture. In the ozone layer, it is one component of a mixture of gasses.
Is ozone a heterogeneous mixture?
No, ozone is a pure substance composed of three oxygen atoms bonded together (O3), so it is not a heterogeneous mixture.
What substance is made up of three oxygen atoms?
Ozone is a substance made up of three oxygen atoms. It is a molecule composed of three oxygen atoms bonded together. Ozone is commonly found in the Earth's atmosphere, where it plays a crucial role in the ozone layer that protects us from the sun's harmful ultraviolet radiation.
Why is an ozone molecule a compound?
An ozone molecule (O3) is considered a compound because it is made up of two different elements, oxygen (O) and forms a distinct molecule with a fixed ratio of their atoms. Each oxygen atom forms a covalent bond with the other two oxygen atoms, making it a chemically distinct substance.
What is the oxidation number of an elementary substance?
The oxidation number of an elementary substance is zero because there is no transfer of electrons between atoms of the same element in a compound. Each atom in an elementary substance is considered to have an oxidation number of zero.
What is the leading substance in ozone layer depletion?
CFC's are leading substance in ozone depletion. They decompose ozone.
What is the substance that has contributed most to ozone depletion?
The substance that has contributed the most is CFC. they react with ozone and deplete it.
What substance is the most harmful to the ozone?
It is CFC. It destroys the ozone.
Is ozone a solution?
No, ozone, a form of the element oxygen, is a pure substance.
What substance is a major threat to the ozone layer?
CFC's are a major threat to ozone. They react with ozone to deplete it.
What is ozone depleting substance?
There are many ozone depleting substances. These substances are the ones that can cause damage to the ozone layer.
What is an ozone depleting substance ods-?
Ozone depleting substances cause damage to the ozone layer. CFC's are greatest of them.
Which substance is considered to be a factor affecting Earth's ozone layer?
Chlorofluorocarbons (CFCs) are substances that have been identified as a major factor affecting Earth's ozone layer. When released into the atmosphere, CFCs break down and release chlorine atoms that can destroy ozone molecules.
What chemical is in chlorine?
There is no other substance in chlorine except chlorine, which is an elementary substance.
Chimecal reaction between nitrogen oxide and ozone?
Nitrogen oxide is formed after reaction with ozone. It is also an ozone depleting substance.
What substance depletes ozone in the stratosphere?
CFC's and HCFC's
