is diet coke a chemical reaction or physical reaction?

Answer 1

Diet coke in a glass has bubbles coming out – that is a physical change.

Diet coke with a Mentos dropped in makes a mess – that is a chemical reaction

Diet coke with Lemon in it makes my wife happy – that is a survival imperative.

Answer 2

if you're talking about the mentos reaction is a physical change. all the sugar does is displace the dissolved CO2 rapidly. physical changes you can easilty reset. chemical reactions take effort to reset

Answer 3

its not a reaction at all. its a substance. that's like asking if water is a chemical reation.
