Two sets A and B are disjoint if they have no elements in common (their intersection is the null set).
show more Ozone, O3(g), is a form of elemental oxygen that is important in the absorption of ultraviolet radiation in the stratosphere. It decomposes to O2(g) at room temperature and pressure according to the following reaction: 2O3(g)>3O2(g) (Delta)H = -284.6 kJ.
The element is oxygen. The molecule or compound formed is O3, called ozone. The mixture this is commonly found in is air. The molecule oscillates between two bondings...O-O=O and O=O-O.The bonding angle is not 180Â°, so the molecule is polar.he ozone layer contains, as does most of the atmosphere, about 78% nitrogen (N2) and 21% oxygen (O2). Ozone (peak value of about 0.0009%) is made from oxygen by the action of UV-C (and more energetic radiation) from our Sun.
