Oxygen gas is never found in a monomer (O), but is always found in either the dimer form (O2), or the trimer form ozone (O3).
O2 can be made by heating potassium chlorate(v) and manganese(iv) oxide.This can be used to make oxygen for scince experiments.This is because Potassium chlorate is a compound containing pottasium, chlorine and oxygen, with the molecular formula KClO3.Manganese(IV) oxide is the inorganic compound with the formula MnO2.
Oxygen ( O2 ) : 21 % ; Nitrogen ( N2 ) : 78 % ;
O2 is a molecule made up of two oxygen atoms. Oxygen itself is an element, but when it combines with another oxygen atom to form O2, it is considered a molecule.
If you start with 4 H2O2 molecules, you would end up with 2 O2 molecules. This is because for every 2 molecules of H2O2 that decompose, 1 molecule of O2 is produced.
O3 or ozone is a molecule composed of three atoms of oxygen.
The solution is made up of 20% O2 and 80% N2 based on the volumes provided.
To top up your O2 mobile phone, you can dial 4444 from your O2 mobile phone and follow the prompts to add credit. You can also top up online, through the O2 website, or at a participating retailer.
Three O2 is a gas. you just add an atom and its a trioxide
Al2O3
The chemical formula for oxygen is O2, which means it is made up of two oxygen atoms bonded together.
The composition of normal atmospheric air is N2 - 78%, O2 - 21% and other miscellaneous gasses make up the balance. SO,Any O2 concentration greater than 22-23% would be O2 considered enriched.
Oxygen ( O2 ) : 21 % ; Nitrogen ( N2 ) : 78 % ;

Air is made mostly of oxygen (O2) and carbon dioxide (CO2).
O2
because there are many elements and compounds in that make it up, eg, CO2 is a compound, but O2 is an element. This means its a mixture not an element.
