O2- is an oxide ion which reacts with metal to form oxides of the metal. For example: MgO, Na2O
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.
150.0 g O2 x 1 mole O2/32 g O2 = 4.688 moles O2
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
2H2O2 ==> 2H2O + O2 the equation is balanced
= H2+O2 =2H2+O2=2H2O
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
o2 is a symbol. A formula is something like O2 + H2 -> H20
O2 is the chemical symbol for oxygen. if something has O2 in it it has 2 oxygen molecules=)
O=oxygen atom, o2=oxygen molecule, o2-=oxide, o22-=peroxide, o2-=superoxide, o3=ozone.
The balanced chemical reaction equation says that you get 3 moles of O2.m O2 = ( n O2 ) ( M O2 )m O2 = ( 3 mol O2 ) ( 32.00 g O2 / mol O2 = 96 g O2
