Is Mentos and Coke a chemical or physical reaction?
Is Mentos and Coke a chemical or physical reaction?
The Mentos and coke experiment is a physical reaction rather than a chemical reaction. Inside a bottle of coke, there is dissolved carbon dioxide gas which is what makes the soda fizzy when you drink it.
What happens when you mix Coke and Mentos?
When Mentos react with Coca-Cola, the following reaction is explosive, rapidly forming a fountain of pressurised Coke that then spurts out of the bottleneck and shoots into the air. These microscopic irregularities on the Mentos’ surface serve as nucleation sites where carbon dioxide bubbles form.
What is the control in the Mentos experiment?
Drop a roll of Mentos into a bottle of Diet Coke. Make sure you have your sneakers on so you can get out of the way fast! Keep the number of Mentos and the temperature of the soda the same. These are your controls.
What causes the reaction between Mentos and soda?
A Mentos dropped into a bottle of soda acts as a surfactant, meaning it reduces the surface tension of the soda. Water molecules are polar and attracted to each other. Anything that breaks them apart allows for bubbles of carbon dioxide gas to form in the solution.
Will Mentos explode in any soda?
Getting the Best Eruption While you can use any carbonated beverage for the Mentos and soda project, there are a few tips to keep in mind to help get the best eruption: Let the soda warm up to room temperature. Like most chemical reactions, the process occurs more quickly at a warmer temperature.
Do fruit Mentos work with Coke?
A study reveals why Mentos and Coke can be a dangerous combination. When mint or fruit Mentos are dropped into a fresh bottle of Diet Coke, a jet of Coke whooshes out of the bottle’s mouth and can reach a height of 10 metres.
Do Mentos explode in Pepsi?
As the Mentos candy sinks in the bottle, the candy causes the production of more and more carbon dioxide bubbles, and the rising bubbles react with carbon dioxide that is still dissolved in the soda to cause more carbon dioxide to be freed and create even more bubbles, resulting in the eruption.
Which soda will explode the highest with Mentos?
The Diet Pepsi exploded the most.
What type of coke reacts best with Mentos?
Diet Coke
Does the flavor of Mentos affect the explosion?
my results we that the mint and diet coke exploded long and was higher. the fruit flavor mentos exploded a little but since it was a different flavor it didnt explode for long.
What can you use instead of Mentos in Coke?
You can substitute another candy for the Mentos, such as M&Ms or Skittles, but ideally, you want candies that stack into a neat column with minimal space between them, have a chalky consistency, and barely fit through the mouth of a 2-liter bottle.
What is the ingredient in Mentos that makes Coke explode?
carbon dioxide
Why does Coke explode when you shake it?
If you shake a can of soda, you end up with tiny bubbles of carbon dioxide gas that stick to the inside surface of the can. If you open the can, the bubbles expand a lot and they push the soda right out with them, causing a “soda explosion.”
How much coke is in a Mentos?
Use a bottle of Diet Coke. Make sure the soda is at least 85 degree Fahrenheit. Drop seven Mentos into the soda all at the same time.
Does shaking soda keep it from going flat?
Shaking a soda allows it to mix with air molecules trapped in the bottle. These air bubbles are the best possible nuclei for the further growth of bubbles. In other words, if you want to keep your soda from going flat, don’t shake it.
Does shaking a fizzy drink make it flat?
Small bubbles caused by shaking help to hasten the escape of the soda’s carbon dioxide. Once the the can is opened, all of the gas will eventually escape from the liquid as bubbles, and the soda will go “flat.” If the liquid is handled gently, it takes a long time for the dissolved gas to escape.
What happened when you shake the bottle?
If you shake the bottle before opening it, some of the carbon that has been floating at the top of the bottle gets suspended in the liquid. If you or your innocent friend open the bottle at this point, the large bubbles will rise very quickly to the liquid’s surface – resulting in an impressive soda explosion!
Does shaking a soda increase pressure?
You might think the pressure inside the bottle increases when shaken, but it does not.
