What type of chemical reaction occurs when you mix Coke with Mentos?

"Why does this work? While there is considerable debate over how and why, here's the hypothesis: Water molecules strongly attract each other, linking together to form a tight mesh around each bubble of carbon dioxide gas in the soda. In order to form a new bubble, or even to expand a bubble that has already formed, water molecules must push away from each other. It takes extra energy to break this "surface tension." When you drop the Mentos into the soda, the Gelatin and gum Arabic from the dissolving candy break the surface tension. Each Mentos candy has thousands of tiny pits all over the surface. These tiny pits are called nucleation sites - perfect places for carbon dioxide bubbles to form. As Mentos hit soda, bubbles form all over the surface of the candy. And, the fact that the Mentos candies sink to the bottom of the bottle gives a double-whammy. When all this gas is released, it literally pushes all the liquid up and out of the bottle in an incredible soda blast."

How does the temperature of coke affect the chemical reaction of coke and Mentos?
no but if it's warm it's not as tasty
What happens when you microwave Diet Coke with Mentos inside of it?
If you put a mentos in the diet coke and put it on the microwave, it will cause a chemical reaction causing your microwave to explode.
What happens if you combine a metos candy with Diet Coke?
If you combine Mentos and Diet Coke, you could get a big boom. The coke will react with the mentos, making a chemical reaction together and create the giant explosion.
What erupts better vinegar with baking soda or Diet Coke with mentos?
Bkng soda vinegar is a CHEMICAL reaction, a chemical change occurs giving CO2 and water. The rate depends on the conc. of your vinegar, temperature and the surface area of the soda (fine powder)Mentos/coke is a PHYSICAL reaction, no chemical change occurs (though sugar dissolves and eventually hydrolyses to glucose, but this is incidental). The same thing happens with Mentos and carbonated water.CO2 dissolved in the coke is released by a process called nucleation on the surface of the mentos.A rough surface is better than a smooth one, so this might be a useful area to investigate for your project.The mentos reaction is probably fastest under most conditions, and you can experiment with temperature, acid strength, different types of Mentos (some are smooth and are rubbish), fizzy drinks with different amounts of sugar dissolved, lots of variables are there if you think about it.
Which soda has a stronger reaction to Mentos?
I strongly believe diet coke has a stronger reaction to mentos!
What are some cool science fair projects?
One cool project is what chemical reaction does mentos and coke make after mixing them!
Is the Mentos and coke experiment exothermic?
No, its an Endothermic Reaction.
What makes the reaction happen in coke and Mentos?
Well mentos have these small pockets on them where the CO2 can gather on and be released very rapidly. This is called nulceation. There is no chemical reaction caffeine, potassium benzoate, aspartame, and CO2 gas contained in the Diet Coke and the gelatin and gum Arabic ingredients of the Mentos all contribute to the jet effect.
What is the replacement reaction to baking soda and vinegar?
I think that Coke and Mentos will do the trick. It has to be REGULAR COKE!The Mint Mentos will work the best.
Why is the coke and Mentos experiemnt a physical reaction?
The Coke and Mentos experiment is a physical reaction and not a chemical one because the chemical compounds involved are not changed. No "chemistry" happens, but only "physics" occurs. Let's look. Carbon dioxide (CO2) gas is dissolved in the Coke, and when the cap is removed, it begins to come out of solution and form bubbles. There is a complex issue regarding exactly where a bubble will form and how it will grow, but bubbles do form and grow. Dump in some Mentos and the surface of each of the Mentos provides a "zillion" sites for bubbles to form. They form quickly, then detach, and more bubbles quickly form. This results in a cascade of bubble formation and the dramatic result we see. And it's all about the CO2 coming out of solution and making bubbles rapidly. Those bubbles carry Coke with them to the top of the bottle as they make their way out, and we see the fountain form. The Mentos and Coke are unchanged, just as the CO2 is unchanged in this physicalreaction.The reaction of Diet Coke and Mentos is a physical reaction. Links can be found below to learn more.
Can you die from eating Mentos and coke?
yes you can because of the chemical reaction between them, your throat will close keeping in the gas and will rupture your stomach.
While shaking the coke with the Mentos will it make a eruption and reaction?
Yes
