Both. The chemical change is H2CO3 decomposing into H2O and CO2. The physical change is the dissolved CO2 forming a bubble and "fizzing" up to the surface.
Fizzing is the result of a chemical change - a chemical reaction with gas releasing.

It is a chemical change

yes it is
Physical
Magnesium fizzing in acid is definitely undergoing a chemical change.
It is a sign that a chemical change is taking place, rather than a physical change.
Physical. If a substance releases bubbles, it is converting some of its liquid into a gaseous state. The chemical properties do not change, only its present state. A most common physical change is that of watching ice melt in glass of water.

is a physical change. The popsicle is still a popsicle even if its freezed, nothing has changed with it but its physical appearance :)
Dissolving and fizzing are physical processes.

No, fizzing after mixing two chemicals is a chemical change.

Fizzing is a chemical property.
Pop cans are produced by physical processes.
The bubbles pop when they reach the surface of the liquid, yes. It makes a fizzing noise.
yes it is
There are signs that you can see when a chemical change takes place. It is true that fizzing or foaming is evidence that a chemical change may have occurred.
Drinking pop can change your PH scale if you drink a lot of it
