Oxygen can be found in H20 (water). It can be separated through electrolysis
The equation for the electrolysis of water is 2[H20]+energy = 2[H2] + 02
oxygen, and water can be found in the air
which of these elements must be in organic compuonds oxygen hydrogen carbon helium or iron
Some oxygen gas is dissolved in the water and can be extracted via gills.
A pearl is not extracted from the earth. They are found in oyster's shells. The term for it is harvesting oysters.
No
They come from naturally found elements and compounds, although they are then extracted from them using man made techniques, you never find them naturally. Gasoline is extracted from oil and polyester is also extracted, they are not naturally found.
Yes, copper is found in its natural state as a metal mineral in the Earth's crust. It is often found in combination with other elements such as sulfur, oxygen, and other metals, and must be extracted through mining and refining processes.
fff
the moder answer id elemenys and compuonds
namely Hydrogen, Oxygen, Sodium, Chlorine and some others
Oxygen is extracted, by the lungs, from the air taken in, and carbon dioxide is released from them. So, there are really two products - oxygen and carbon dioxide.
Helium is chemically inert and does not form any compounds.
