Recommended: the speed or rate of a chemical reaction is influence by what

One of the most popular science experiments throughout schools is Diet Coke and Mentos. When put together they make an eruption of fizziness. Diet Coke and Mentos form a physical reaction when put together, and I am going to explain how this popular science experiment works. First of all, mentos are a big part of this project. The ingredients of regular mint Mentos are sugar, wheat glucose syrup, hydrogenated coconut oil, rice starch, gum arabic, sucrose esters of fatty acids, gellan gum, and natural flavors (Becker, 2017). Mentos may look smooth when looked at, but they have tiny bumps along the surface when looked at with a microscope.The bumps on the mentos make great nucleation sites. These bumps allow the carbon dioxide gas and water in soda to break apart. When these bonds break it forms the bubbles that cause this big eruption (Buddies, 2012). …show more content…

Mentos already sink quickly due to their density. If dropped in faster, they will sink even faster than just dropping them in. The faster they’re dropped in, the faster the eruption happens. Also, if dropped in all at once, the reaction will be a lot greater (New Scientist). Another thing that affects the reaction is how many Mentos are poured in the bottle of Diet Coke at the same time. The amount of Mentos put in is a big factor in this experiment. The more Mentos that are put in, the bigger the eruption will be because their will be even more nucleation sites for the Diet Coke for nucleation (Eepy Bird). The last thing that can improve this experiment is using rock salt. Using rock salt will make your reactions a lot better and it will go farther (Wayne

    In the experiment “ Talking to plants “ from Mythbusters, potential problems include the use of greenhouses with no sound insulation, a non-homogeneous location and the use of only one specie to infer on a population. In another scientific study, researchers chose to use “ a noiseless growth chamber to prevent any effects from extraneous noise “ and the use “ growth chambers under continuous light at 28 c and 65-75% relative humidity “ in order to maintain a homogeneous location for all plants during the experiment (Jeong et al., 2008) . This helped further explain the findings because with the use of noiseless chambers you can assure that the only noise that the plant was receiving was the one given in the treatment and a valid conclusion

    Here is how I did my experiment. First I formed my hypothesis, and I thought about how I should go about doing it. I decided to use Vinegar (Acetic Acid) and Baking Soda (Sodium Bicarbonate). I used these because they are the basic and well known chemicals used in the "Volcano" project, which is a bubbling, fizzing foam caused by mixing almost any amount of vinegar and baking soda. I first used any amount for a test, in this case it was a one to one ratio.

  • Caffeine Free Soda Experiment

    1522 Words  | 4 Pages

    Per the hypothesis, most of the results in the lab are in accordance with the expected results. It was expected that the subjects drinking caffeine, diet caffeine free soda, and 16 ml/Kg of water would have a higher rate of production than the control group drinking 7.5 ml/Kg of water due to less water being reabsorbed. Results showed an increase in rate of production, most notably in subjects drinking diet caffeine free soda but seemed to decrease towards the end. For the rest of the subjects, the data shows a gradual rise over time with every subject (besides caffeine free) having a higher rate of production than the control group. The subjects drinking caffeine free soda were the only ones to record a lower rate of production than the control group. This could be due to an increase in glucose reabsorption causing water to follow back into the blood stream. The lack of caffeine does not hinder ADH secretion, which will cause an increased permeability to water in the collecting

  • Energy Drinks Experiment Essay

    Energy drinks affect your body in ways people don’t think about. My experiment was created to find out what happens to your heart rate after putting an energy drink into your body. Some of the things I found by doing some research is that you can go to the hospital just for drinking an energy drink alone. Energy drinks contain more caffeine than what the label says. Based on this research a hypothesis was created. The hypothesis was, if you drink an energy drink, then your heart rate will increase due to the amount of caffeine it contains. This hypothesis made the most sense because caffeine has been labeled by doctors to not be the safest substance.

  • Comparison of the Densities of Coke and Diet Coke

    684 Words  | 2 Pages

    In this experiment, there were several objectives. First, this lab was designed to determine the difference, if any, between the densities of Coke and Diet Coke. It was designed to evaluate the accuracy and precision of several lab equipment measurements. This lab was also designed to be an introduction to the LabQuest Data and the Logger Pro data analysis database. Random, systematic, and gross errors are errors made during experiments that can have significant effects to the results. Random errors do not really have a specific cause, but still causes a few of the measurements to either be a little high or a little low. Systematic errors occur when there are limitations or mistakes on lab equipment or lab procedures. These kinds of errors cause measurements to be either be always high or always low. The last kind of error is gross errors. Gross errors occur when machines or equipment fail completely. However, gross errors usually occur due to a personal mistake. For this experiment, the number of significant figures is very important and depends on the equipment being used. When using the volumetric pipette and burette, the measurements are rounded to the hundredth place while in a graduated cylinder, it is rounded to the tenth place.

    In this experiment, the calcium carbonate was in the form of marble chips. The calcium carbonate reacted with hydrochloric acid when the acid was poured into marble chips. Due to calcium carbonate’s higher reactivity, it displaced hydrogen in the hydrochloric acid. As a result, products of calcium chloride, carbon dioxide and water were formed. As the chemical reaction occurred, the water in the measuring cylinder was displaced and gas bubbles that were blowing out represented carbon dioxide.

  • Rate Of Reaction Between Magnesium And Hydrochloric Acid

    1605 Words  | 4 Pages

    Looking at the table of results above and the graph, it is shown that the higher the temperature got, the shorter the reaction time. The obtained results have been plotted on a line graph of the temperature of hydrochloric acid (y-axis) against reaction time (x-axis). This line graph in fig.2 also clearly shows that as the temperature increases, so does the speed of the reaction, shown by a reduction in the time taken. This corroborates the collision theory, where as the temperature of particles increase, the particles gain more kinetic energy and react with each other upon collision. This is shown as to happen in the hydrochloric acid, where the hydrochloric acid particles collide more with the particles of the magnesium ribbon as the temperature was increased. The above graph shows a gradual sloping curve, which gets steeper at higher temperatures. This shows that the reaction will reach a peak rate of activity as the gaps between the temperature and reaction times continue to decrease. The experiment fulfills the aim and clearly shows that as the temperature of a reaction is increased so does it’s rate of reaction, proving the hypothesis to be correct.

  • Essay On Vinegar And Baking Soda

    1309 Words  | 3 Pages

    So what exactly is matter? Matter is anything that has mass and takes up space (blue book). The particle model, however, is different for the four types of matter. For solids, the molecules can only vibrate, but solids have a definite shape and volume. For liquids the molecules are able to slide past one another and has definite volume. Both gas and plasma don't have a definite shape or volume, but in gas the molecules can move freely and bump into each other, and in plasma the molecules have completely broken apart. These molecules are too small to see and are different for every object. So what do particles have to do with vinegar and baking soda reacting? Well acids and bases are made of elements. These elements are made of atoms which are made of molecules. So when you get down to it, the reaction between acids and bases all depend on the particles of the object.
