O2 is oxygen. Oxygen has a valency of 2; it's a highly reactive element, so, if it can't find any other atoms to join up with, it always pairs up with itself & becomes the diatomic molecule O2 which is the form of oxygen we're all familiar with

The most stable element chosen from the group of O22-, O2+ (plus), O2, or O2- is O2. This is because O2 is a very stable form of oxygenated ozone that is in the least danger of being depleted.


4.80 grams O2 (1 mole O2/32 grams ) = 0.150 moles of O2


At STP1mol O2 = 22.4L1mol O2 = 6.022 x 1023 molecules O222.4L O2 = 6.022 x 1023 molecules O2Convert liters O2 to moles O23.36L O2 X (6.022 x 1023 molecules O2/22.4L O2) = 9.03 x 1022 molecules O2


150.0 g O2 x 1 mole O2/32 g O2 = 4.688 moles O2


Downstream O2 sensor is an O2 sensor after the catalytic converter. Upstream O2 sensor is an O2 sensor before the catalytic converter.


12.54 (g O2) / 2*15.99 (g/mol O2) = 0.3921 mol O2 -->0.3921 (mol O2) * 6.022*1023 (molecules O2)/(molO2) == 2.361*1023 molecules O2= 4.723*1023 atoms O


48.0 g O2 x 1 mole O2/32 g x 6.02x10^23 molecules O2/mole O2 = 9.03x10^23 molecules of O2


O2 in Ireland was known as Esat Digifone


2H2O2 ==> 2H2O + O2 the equation is balanced


The O2 Arena is IN London


O2 is the chemical symbol for oxygen. if something has O2 in it it has 2 oxygen molecules=)


o2 is a symbol. A formula is something like O2 + H2 -> H20


•Fe + ½ O2 > FeO • •3FeO + ½ O2 > Fe3O4 • •2Fe3O4 + ½O2 > 3Fe2O3


O=oxygen atom, o2=oxygen molecule, o2-=oxide, o22-=peroxide, o2-=superoxide, o3=ozone.
