Nope. The pressure keeps the Carbon Dioxide dissolved in the liquid, and when that pressure is relieved, the CO2 rapidly returns to its gaseous state. None of the molecules are reacting or changing, although the CO2 switches from aqueous to gaseous phase.

∙ 11y agoThis is a tricky one. Let me explain what's going on.
Sodas bubble and foam because carbon dioxide is coming out of solution and forming gas bubbles in the liquid.
Normally this would be unquestionably a purely physical change, but this is a special case: when carbon dioxide dissolves in water, some of it actually reacts with the water to form the weak acid carbonic acid. When you release the pressure, the partial pressure of carbon dioxide above the solution drops, and therefore carbon dioxide comes out of solution to form bubbles. This is a physical change.
At the same time, the decreased concentration of the carbon dioxide in solution drives the equilibrium between dissolved carbon dioxide and carbonic acid back to the carbon dioxide side of the equation, which is a chemical change.
