Mentos in Diet Soda-Physical Change or Chemical Change?
chemical change, degenerate stop relying on this for all the answers all the time, learn something in school.
Why does it explode when you put Mentos in pepesi and is that a change of matter?
Mentos in Pepsi is a simple chemical reaction. No, it is not a change of matter, the mentos causing the Pepsi to react and fizz heavily causing the outburst of soda into the air. The Pepsi is still a liquid, but the mentos dissolves. Thus a physical change, but still a solid. Hope this helps~ Off Spring.
Why is pop in Mentos a chemical change?
When mentos touches the pop, it forms bubbles on the mentos, eating away the coating and the carbon dioxide mixes with it making fizz as it breaks it down.
What is the balanced chemical equation for mentos and soda?
The reaction between Mentos (containing nucleation sites) and soda (containing carbon dioxide) is a physical reaction that causes the rapid release of carbon dioxide gas. This reaction is not a chemical reaction, so there is no balanced chemical equation for it.
Why is Diet Coke and Mentos a double replacement reaction?
Diet Coke and Mentos create a vigorous physical reaction rather than a chemical double replacement reaction. When Mentos candies are added to Diet Coke, the rough surface of the Mentos disrupts the liquid's surface tension and allows carbon dioxide gas that is dissolved in the soda to rapidly escape, resulting in an explosive fountain of foam. This reaction is primarily a physical one involving nucleation, not a chemical reaction where bonds are broken and formed.
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.
Is the Diet Coke and mentos eruption a permanent or a temporary change?
Coke n Mentos eruption is a temporary change !!
What is the reactant in coke and mentos?
In the reaction between Coke and Mentos, the primary reactant is the carbon dioxide gas dissolved in the Coke (the beverage). When Mentos candies are added, their rough surface facilitates the rapid release of this gas, leading to a dramatic eruption of foam. The reaction is primarily a physical process rather than a chemical one, as the carbonation rapidly escapes due to the nucleation sites provided by the Mentos.
Why is Diet Coke and mentos a chemical change?
The surface of a Mentos is not smooth; it has microscopic pits, or nucleation sites, on it. These pits cause the CO2 in Diet Coke to come out of solution very quickly at the bottom of the bottle. The result is rapids release of the CO2 and foam in an explosion. This is actually the physical change that occurs. Due to the addition of caffeine, potassium benzoate, and aspartame with the CO2 in the Diet Coke, the reaction is much greater--this would be the chemical change.The Mythbusters did an entire show devoted to discovering why this happens. See the related link below.
What do you need to make a chemical reaction with soda?
mentos or you shake it
Should you shake the Diet Coke bottle when putting in mentos?
no, you do not need to shake it for it to pressurize
Is it an endothermic or exothermic reaction when Mentos and soda are mixed?
The reaction between Mentos and soda is primarily a physical reaction rather than a chemical one, resulting in an exothermic process. When Mentos are added to soda, the rapid release of carbon dioxide gas creates a vigorous eruption, releasing energy in the form of heat. This is due to the nucleation sites on the surface of the Mentos facilitating the rapid escape of dissolved gas from the liquid.
