Yes. The molecules have the formula O2.
Mainly hydrogen - which is currently the most abundant element in the Universe.
Oxygen gas is made up of one substance = oxygen. So oxygen gas is not a compound
Many gases are made of molecules and exist at room temperature. The atmosphere is mainly oxygen and nitrogen, both these have molecules with two atoms. O2 and N2. Then there are small amounts of other gases like carbon dioxide CO2, methane CH4, sulphur dioxide SO2. So there are plenty of molecules.
In a container of oxygen gas, there are only oxygen atoms present. Oxygen gas consists of molecules made up of two oxygen atoms bound together (O2).
Oxygen gas - O2 Hydrogen gas - H2
Yes, oxygen gas is a homogeneous mixture in its pure form. It is made up of oxygen molecules (O2) that are evenly distributed throughout the gas, resulting in a uniform composition.
No elements can be made from molecules, because molecules are made from elements instead. If the question is really, "What elements normally occur in nature as diatomic molecules?", the answer is hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine.
the answer is ozone...O3 water vapour (2 hydrogen, 1oxygen)
There is no such thing as 02 gas. Perhaps you meant O2 gas, which is oxygen gas, consisting of molecules made of two oxygen atoms bonded together. O2 is essential for respiration in living organisms and combustion in fires.
Oxygen is considered an element because it consists of atoms with the same number of protons in their nucleus. While oxygen gas in the atmosphere is made up of diatomic molecules (O2), each molecule contains two oxygen atoms bonded together. These individual oxygen atoms are still considered elements because they cannot be broken down into simpler substances by ordinary chemical reactions.
6H2 + 6O2 ---> 6H2O + 3O2 This reaction leave excess unreacted oxygen behind.
None Oxygen is oxygen, so to speak. It is an element itself, so is not a compound made of other elements.
