What is the reaction between Mentos and Coke called?
soda geyser
A Diet Coke and Mentos Eruption (also known as a soda geyser) is a reaction between the carbonated beverage Diet Coke and Mentos mints that causes the beverage to be expelled from its container.
What is inside Mentos and cola that reacts with each other causing the eruption?
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.
Is Coke and Mentos a synthesis 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 is the purpose of the Coke and Mentos experiment?
Carbon dioxide is the chemical compound that consists of two oxygen atoms bonded to a carbon atom. Carbon dioxide creates the bubbles in soda. The goal of this project is to explore the eruption of carbon dioxide when the candy Mentos dissolves in Diet Coke.
What evidence did the team find that the reaction between the Mentos and soda was a physical change?
Coke and Mentos. Mixing Coke and Mentos looks like a chemical change, but since the gas released is carbon dioxide AND it was present before the foaming happened, it is actually a physical change.
What is the hypothesis for the Diet Coke and Mentos experiment?
Hypothesis: If the amount of soda in the bottle decreases, then the height of the plume and velocity of the liquid will also decrease because there will less liquid with which the Mentos can react.
Why does Mentos only react with Diet Coke?
Diet Coke and Coke Zero react better with Mentos than regular Coke does because of the absence of sugar. A lack of sugar makes the soda mixture less viscous, given the presence of sweeteners, like aspartame, lowering the surface tension even more than usual.
Are Mentos acidic or basic?
Many people speculated that the geyser was the result of an acid base reaction, given the low pH of soda. However, none of the ingredients in mentos are basic, and the experiment works to some degree with any type of soda and any type of candy. Mentos candies are not as smooth as they appear to the naked eye.
What is the conclusion of Mentos and Diet Coke?
Conclusion: The Diet Coke reacted to the Mentos, which means the hypothesis was correct. The question in the hypothesis was answered too, with the answer being no. Regular Coke does not work with Mentos because the Diet Coke uses Aspartame instead of sugar, which regular Coke uses.
What is the control in the Mentos experiment?
Keep the number of Mentos and the temperature of the soda the same. These are your controls.
What is the evidence that the gas made in Mentos soda demo was carbon dioxide?
What is the evidence that the gas made in the mentos + soda demo was carbon dioxide? The evidence is that when the balloon is expanding.
What is the dependent variable in Mentos Coke experiment?
The independent variable to this experiment is the Mento because it could stand alone and it does not depend on. The dependent variable is the the Diet Coke with the mentos because it depends on the mentos to have a chemical response.
What happens when you put Mentos in Diet Coke?
But the amazing eruption that takes place when Mentos are dropped into Diet Coke or other brands of diet soda pop is not a chemical reaction at all! Instead it is a physical reaction. That means that all of the pieces of the reaction are there, but that they are simply rearranged.
What causes Mentos to react to carbon dioxide?
In non-sciency terms, basically, this porous surface creates a lot of bubble growth sites, allowing the carbon dioxide bubbles to rapidly form on the surface of the Mentos. If you use a smooth surfaced Mentos, you won’t get nearly the reaction.
What causes Mentos candy to erupt in soda bottle?
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.
What happens to Mentos when you crush them?
Mentos are also fairly dense and sink rapidly, quickly creating bubbles that seed further bubbles as they rise. Crushed Mentos that fell more slowly created puny fountains that only travelled about 30 centimetres.
