The carbon dioxide molecules attach to the surfaces of the Mentos like they did in the cup of soda. All those Mentos in a lot of soda make a lot of bubbles that rise to the surface and push the soda out in a big woosh!
Why is Coke and Mentos not a chemical reaction?
Dropping Mentos into coke or lemonade allows the dissolved gas within the liquid to come out of the liquid super-fast at these nucleation points on the Mentos surface. Thus the Coke and Mentos reaction is a physical one, not a chemical reaction.
What is a physical reaction example?
Examples of physical reactions are boiling or freezing water, breaking glass, and dissolving sugar in water. In each case, the physical properties change but the chemical properties remain the same.
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 is the conclusion of Mentos and Diet Coke?
The blend of Coke Zero and Mentos just works out the strongest. In conclusion the hypothesis that the diet coke will have the greatest explosion because of the high level of CO2 gas contained in it was correct.
What happens if you put Mentos in Coke and close the cap?
How many Mentos are in Coke?
The goal is to drop all seven Mentos into the bottle of soda at the same time, which is trickier than you might think. One method for doing this is to roll a piece of paper into a tube just big enough to hold the loose Mentos, like a roll of coins.
What are 10 examples of a chemical reaction?
- Burning of paper and log of wood.
- Digestion of food.
- Boiling an egg.
- Chemical battery usage.
- Electroplating a metal.
- Baking a cake.
- Milk going sour.
- Various metabolic reactions that take place in the cells.
How do you know if its a physical or chemical change?
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed.
What is an example of a chemical reaction?
A chemical change happens when a substance’s chemical identity changes. An example of this is rusting. When an iron nail comes into contact with water and is then exposed to the air, it rusts, forming a brown-red substance. This process changes the chemical composition of the original substance.
What are the variables in the Coke and Mentos experiment?
This is the experiment’s variable. The variable could be something like the number of mentos dropped into the bottle, the flavor of diet soda, the size of the bottle, or the temperature of the soda.
Does the flavor of Mentos affect the explosion?
Does the flavor of Mentos affect the explosion? The answer is yes. But it has nothing to do with the mint Mentos’ actual flavor. The mint Mentos mixed with diet coke usually explodes the longer and higher while fruit Mentos has a more delayed and less impressive reaction.
Which soda will explode the highest with Mentos?
The results showed that Diet Coke created the most spectacular explosions with either fruit or mint Mentos, the fountains travelling a horizontal distance of up to 7 metres.
Does the amount of Mentos affect the height of the explosion?
Conclusion: The more mentos you put in a bottle of pop does not necessarily mean a larger explosion. We found that the max amount of mentos with the largest explosion was 4 mentos, it went 350 cm high. With 5 or 6 mentos the explosion went only 330 and 310 cm high.
Does Mentos work with regular Coke?
Any Carbonated Beverage Works The trick works with any carbonated beverage. It works with regular cola, orange soda, root beer, etc. It’s actually very cool when performed with tonic water under a black light because you get a glowing blue fountain.
How many Mentos and Coke are in a volcano?
Drop 4-5 whole Mentos into the bottle all at once. Quickly remove the funnel and back away as the bottle will soon spout off fizzy soda.
Can you freeze Mentos in ice cubes?
Which soda is best for Mentos?
Diet Coke (far right) produces the best effect for the Mentos soda eruption.
How many Mentos come in a roll?
They are typically sold in rolls which contain 14 mint discs, although the “Sour Mix” variety contains only 11 discs per roll. Smaller versions also exist, typically containing 4 to 6 discs per roll.
What are 3 examples of a physical change?
A physical change is a change in appearance only. The matter is still the same after the change takes place. Examples of physical change include, cutting paper, melting butter, dissolving salt in water, and breaking glass.
What is the 5 examples of physical change?
Some common examples of physical changes are: melting, freezing, condensing, breaking, crushing, cutting, and bending. Some, but not all physical changes can be reversed. You could refreeze the water into ice, but you cannot put your hair back together if you don’t like your haircut!
What are the 10 examples of physical changes?
- Crushing a can.
- Melting an ice cube.
- Boiling water.
- Mixing sand and water.
- Breaking a glass.
- Dissolving sugar and water.
- Shredding paper.
- Chopping wood.
What is an example of both a physical and chemical change?
Burning of wood is a example of both physical and chemical change. When wood is burnt the moisture present in it turns to vapour ,it is a physical change while it burns and generate CO2 is a chemical change. Answer: Burning of wood is a example of both physical and chemical change.
Which is not an example of chemical reaction?
The correct answer is option 1 i.e Changing of water to water vapour. Changing water to water vapour is NOT an example of chemical change.
What are signs of a chemical reaction?
- Color Change.
- Production of an odor.
- Change of Temperature.
- Evolution of a gas (formation of bubbles)
- Precipitate (formation of a solid)
