Okay I turned on my thinking cap a little bit, and I hoping to confirm my hypothesis!
So, I was thinking about Canned Soda, and how the Carbonation rises, and how after time, all carbonation is gone, but there is now Oxygen mingling with the pop.
So seeing as the Law of Conservation of Mass concludes, mass is neither created nor destroyed, what happens to the Carbonation once the chemical reaction between the soda and the Oxygen occurs?

Soft drinks are bottled under pressure.
That's why unopened bottles and cans feel so rigid, but opened containers are easily deformed.
That space above the liquid in an unopened bottle is filled with pressurized CO2.
That gas is in equilibrium with the CO2 that is dissolved in the liquid.
(That means CO2 is constantly escaping into the space, and constantly being redissolved in the liquid, so the mass of dissolved CO2 is constant.)
This makes sure the soda is fizzy when the container is opened.
When the cap is opened the CO2 above the liquid escapes, and causes the psst sound that you hear.
The equilibrium is broken. The CO2 escapes into the atmosphere. On a sensitive enough balance you would observe a decrease in mass of the open soda because of the loss of carbonation. The CO2 hasn't been destroyed, it's just not in the object being measured any longer.
Now about the oxygen. The main change is not chemical, but physical. Because the oxygen in the air is in contact with the soda, some of it will be captured and dissolve in the soda. Like the CO2, an equilibrium will be established and the oxygen will be captured and escape from the surface of the soda.
Fish rely on the oxygenation process to provide the dissolved oxygen they need to "breathe." The amount of dissolved oxygen can be increased by making the water turbulent which is why aquaria and ponds have circulation pumps and water falls and such.
