Is putting mentos in coke a physical or a chemical change?
its a physical change
Is putting vanilla in coke a chemical or physical change?
Mixing vanilla with coke would be considered a physical change because no new substances are formed. The chemical composition of both vanilla and coke remains the same even after mixing them together.
Is a warm coke bottle fizzes when opened a chemical change?
No, the fizzing of a warm Coke bottle when opened is not a chemical change; it is a physical change. The fizzing occurs because the carbon dioxide gas that was dissolved in the liquid is released when the pressure is reduced upon opening the bottle. This release of gas is a physical reaction rather than a chemical one, as the chemical composition of the Coke remains unchanged.
Would coke turning into a coke-flavored popsicle of coke be a chemical or physical change?
Freezing Coke into a Popsicle would be a physical change. This is because the substance itself isn't changing (the Coke is still Coke, the molecules are just arranged in a slightly different way). One way to think about the difference between chemical and physical changes is by considering the nature of what you've created by causing the change. For example, by burning paper, you create something completely different than the paper itself: carbon dioxide, some water, and some heat. None of those things even resemble paper, so it's a safe bet that it's a chemical change. If you were to tear the paper in half, however, you still have paper. Nothing has fundamentally changed about it, you just have a couple pieces now. This is an example of a physical change. Another way to envision the differences between chemical and physical changes is to consider how to reverse the change. In most cases, if the change can be easily reversed, it is a physical change. In your case, to change the Coke Popsicle back into Coke, you'd simply have to heat it back up. In the case of frying an egg, it's impossible to unfry it. This is a good indication that a chemical change has taken place. Formally, a physical change is any change that does not affect the substance's chemical identity. A chemical change is a change in which bonds are broken and/or formed, changing the chemical identity of the substance.
What happends if you shook a soda can and some of the fizze came out would it be a physical or a chemical change?
Physical because it is changing in the sense that its fizzing your coke was/is coke before and after you opened/shook your can.

When soda goes flat is it a chemical or physical change?
When soda goes flat, it is primarily a physical change. The carbon dioxide gas that makes the soda fizzy escapes into the air, causing the bubbles to disappear. The composition of the soda remains the same, although its texture and taste may change.
Why is Diet Coke and mentos a chemical change?
The surface of a Mentos is not smooth; it has microscopic pits, or nucleation sites, on it. These pits cause the CO2 in Diet Coke to come out of solution very quickly at the bottom of the bottle. The result is rapids release of the CO2 and foam in an explosion. This is actually the physical change that occurs. Due to the addition of caffeine, potassium benzoate, and aspartame with the CO2 in the Diet Coke, the reaction is much greater--this would be the chemical change.The Mythbusters did an entire show devoted to discovering why this happens. See the related link below.
Which chemical use in coke?
Phosphoric acid is used in Coke.
Why does coke change color with chicken in it?
Cause I told the coke to change color
What kind of soda changes the color of a penny?
Coke or sprite will change the color of a penny.
Why is Diet Coke and Mentos a double replacement reaction?
Diet Coke and Mentos create a vigorous physical reaction rather than a chemical double replacement reaction. When Mentos candies are added to Diet Coke, the rough surface of the Mentos disrupts the liquid's surface tension and allows carbon dioxide gas that is dissolved in the soda to rapidly escape, resulting in an explosive fountain of foam. This reaction is primarily a physical one involving nucleation, not a chemical reaction where bonds are broken and formed.
