I want to know if ALL equations have to be balanced? Say for example if Hydrogen gas (H2) burns in air (O2) to form water (H2O) I get the following:
H2 + O2 --> H2O. Means that balanced would be 2H2 + O2 --> 2H2O.
I dont understand why this also is not correct:
H2 + O2 --> H2O + O- (anion)
Isnt the above also correct since the Oxygen atom from the reactants is displaced? Doesnt it still abide by the law of conservation?
