What is the dependent variable in Coke and Mentos?

What is the dependent variable in Coke and Mentos?

The hypothesis was that if unaltered mentos were dropped into coke, then they would create a more explosive reaction than any of the altered mentos. normal, unaltered Mento. The independent variable was the altering of each Mento. The dependent variable was the height of the rise of Coca-Cola.

What is a good hypothesis for Coke and Mentos?

Hypothesis: If a certain amount of Mentos are dropped into a container of soda, then the container with the most Mentos dropped into it will produce the most CO2 at the fastest rate. This will happen because the dissolved CO2 will provide the most nucleation sites to come out of the solution.

What is the control group in the Mentos and Coke experiment?

In an experiment, you have two groups: an experimental group, and a control group. Open the soda bottle, set it down and write down what you observe about it. This will count as your control group. It’s what happens when you put nothing in the soda.

What is the chemical composition of Mentos?

Ingredients. Mint-flavored Mentos contain sugar, wheat glucose syrup, hydrogenated coconut oil, rice starch, natural flavors, gum arabic, sucrose esters of fatty acids, gellan gum, carnauba wax, and beeswax.

What is the independent variable in the Mentos and Diet 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 kind of Mentos are used for volcanoes?

roll of mint Mentos (type of candy) clear 2-liter bottle of Coke (diet works better)

Is Mentos a base or acid?

It’s Not an Acid/Base Reaction But they do have one thing in common: carbon dioxide.

Who invented Mentos?

Michael and Pierre van Melle
On a train ride to Poland, brothers Michael and Pierre van Melle came up with the vision of a peppermint flavored caramel candy to go by the name of Mentos. This was the beginning of a Fresh New World.

What is the independent variable in the Mentos experiment?

If you drop a different number of Mentos into several different kinds of soda, how do you know what makes the larger geyser, the number of Mentos or the type of soda? independent variable and the dependent variable. The independent variable is the thing that changes in the experiment.

What happens when you add Mentos to Diet Coke?

For the Mentos–Diet Coke reaction, the carbonic acid and carbon dioxide are not products of a chemical reaction but are already present in the Diet Coke, whose equilibrium is disturbed by the addition of the Mentos. Procedure

Why does Diet Coke have carbon dioxide in it?

It’s All About Texture. Coffey and company discovered that the ingredients in the Mentos and Diet Coke and, more importantly, the structure of the Mentos, allow carbon dioxide bubbles to form extremely rapidly. When this happens fast enough, you get a nice Diet Coke fountain.

How is the temperature of Diet Coke measured?

To prevent explosion of the bottles during heating, the heated bottles were opened to release some of the internal pressure, then closed again. • This may have caused some systematic error as compared to the room temperature trials. • Soda temperature was measured with mercury thermometer immediately prior to reaction.

How to make a Mentos and soda fountain?

Now, make a Mentos-and-soda fountain! 1. Slowly and carefully open a new bottle of Diet Coke. 2. Place it on a flat area outside where it is OK to get wet with soda. 3. Put the open end of your tube of Mentos on the card and place it directly over the opening of the soda bottle.
