Question : Why does O2 seem to just disappear from the balanced reaction?

Answer : Potassium Permanganate is an oxidant which will accept electrons depending on the pH at the time of the reaction. In neutral to alkaline solutions, it will form insolubile manganese oxide (MnO2), accepting three electrons, in acid solutions it will form Mn2+ ions. Oxalate is an organic acid rest with a C-C bond and the sum formula (CO2)2 2-. It reacts as a reductive agent and will donate two electrons and accept negative charged two Oxygen atoms (from the water or the Permanganate), forming two carbonate ions. Strictly speaking, not carbon dioxide but dissolved sodium and potassium carbonate will be the product of the reaction.

Question : It tastes like strawberry and guava fruit. It goes down really smooth. And doesn't really taste like liquor. I had the shot at a bar one night. But I don't remember the name of it. Or what else is in it.
