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.
This 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.
No, opening a soda can is a physical change. The chemical composition of the soda inside the can remains the same before and after it is opened.

Is pouring soda into a cup chemical change?
No, pouring soda into a cup is a physical change because the molecules of the soda remain the same. Chemical changes result in the formation of new substances with different chemical properties.
Is baking soda a physical or a chemical change?
Baking soda undergoing a reaction to produce carbon dioxide gas when heated is a chemical change. This is because new substances are formed during the process.
Why is baking soda is a chemical change and physical change?
Baking soda undergoing a chemical change occurs when it reacts with an acid to produce carbon dioxide gas, changing into a new substance. A physical change involving baking soda might be when it is dissolved in water, as it remains chemically the same but changes form.
Is baking soda mixed iodine solution a chemical change?
Mixing baking soda with iodine solution would not cause a chemical change. It would be a physical change where the substances are still present as they were before mixing, and they can be separated.
Is baking soda reacting with vinegar a physical or chemical change?
The reaction between baking soda and vinegar is a chemical change because new substances are formed during the reaction. Carbon dioxide gas, water, and a salt are produced as a result of the reaction, demonstrating a chemical transformation.
Is vinegar and baking soda a physical change or a chemical change?
It is a chemical change
Is baking soda losing mass when heated a chemical or physical change?
mixing baking soda with water is a physical change b/c you don't change the chemical structure mixing baking soda with vinegar is a chemical change b/c you change the chemical structure ================= It is definitely a chemical reaction resulting in a chemical change.
Is a soda a chemical change?
Soda is not a chemical change it does not change in color, flavor, and texture if it's a chemical change it would do that stuff to change but it isn't read this definition a chemical change is a change that produces new substances with new properties
Is making a volcano with baking soda and water a chemical or physical change?
The vinegar-baking soda reaction is a chemical change.
Is mixing vinegar and baking soda physical change or chemical change?
It is a chemical change
Is Vinegar And backing soda reaction a physical or Chemical change?
Chemical change
Is baking soda mixed with iodine a chemical or physical change?
Chemical Change
Is opening a can of soda a chemical reaction?
Opening a can of soda is not a chemical reaction because no new substances are formed. It is a physical change where no chemical bonds are broken or created. The release of gas when the can is opened is due to the pressure change, not a chemical reaction.
Is soda freezing in the freezer a chemical change?
Soda freezing in the freezer is a physical change and not a chemical change. This is because the liquid is only changing into a solid.
Is pouring soda into a cup chemical change?
No, pouring soda into a cup is a physical change because the molecules of the soda remain the same. Chemical changes result in the formation of new substances with different chemical properties.
Is crushing a soda can a chemical change or a physical change?
Physical
Is putting ice in a soda to make it cold a physical or chemical change?
Putting ice in a soda to make it cold is a physical change. The ice melts into water, but it does not change the chemical composition of the soda itself.
