What Affects Mentos/Diet Coke Reaction?

The experiment is to observe a variety of chemical reactions and to identify patterns in

Procedure: In this experiment, various chemicals were mixed together, to determine a reaction. Using two drops from chemical 1 and two drops of chemical two, unless otherwise stated, then recording the type of physical reaction or color changes that occurred.

The main objective of this experiment is to differentiate between a physical change and a chemical change.

The purpose of the experiment was to help us better understand how water, Coke and Gatorade effected the renal system. The goal was to test and see if my hypothesis were correct regarding the urine specific gravity, urine flow rate, and presents of reagents using the Labstix. My hypothesis for this experiment was that the Gatorade drinkers will have the highest urine flow rate and that non-drinkers would have the highest urine specific gravity. Water is hypo-osmotic and coke contains a high amount of sugar making it hyperosmotic relative to plasma. Gatorade consists of large amounts of electrolytes making it iso-osmatic relative to the plasma. Based on these characteristics of the consumed substances, we are able to study the hormonal effects on the average UFR and USG.

Hypothesis: If the concentration of an substrate is increased then the time it takes for the yeast spheres to rise will decrease because there is more substrate for the enzyme to break down, creating more oxygen, faster.

In Part C of the experiment, the process completed in Part B was performed again on the six Kool-Aid drink samples: black cherry, cherry limeade, grape, mixed berry, strawberry, and tropical punch. The cherry limeade, grape, mixed berry, and tropical punch samples were undiluted stock solutions that were used in the SpectroVis. The black cherry solution was diluted with a 2-fold dilution. The 3 mL of black cherry solution was diluted with 3 mL of deionized water. This was done because the Red 40 dye was too concentrated. The strawberry solution was first diluted by a 2-fold but the absorbances values were too high and fell outside the acceptable range of 0-1. Therefore, 8 mL of strawberry solution was diluted with 12 mL of deionized water. These values for all of the solutions were recorded in Table 5. The solutions were emptied down the sink. All the glassware and cuvettes were rinsed with deionized water and dried. The volumetric flasks and caps were returned to the appropriate containers.

During the experiment, two different techniques to disturb systems at chemical equilibrium are utilized. The first one is changing the concentration of one of more species that are involved

Objective : To demonstrate the differences between physical and chemical changes while observing the laws of conservation of matter and energy.

The diet coke and Mentos experiment has been a favorite of amateur scientists, but how does it work? There have been debates, and scientists have concluded that the diet coke and Mentos is a physical reaction, called nucleation. Nucleation sites are areas that have high surface with low volume. Such places can be your fingerprint, scratches on glass, specks of dust, or even Mentos candy (Eepy Bird). Mentos candies have a pitted surface that’s rough when looked at through a microscope, therefore creating a wonderful place for nucleation to occur. Water molecules like to be next to other water molecules, so if you drop something into the soda, like Mentos, it acts as a site for growth of bubbles. Mentos have a high

This paper is a Science Fair Project about Coke and Mentos Reaction. This essay is not going to tell you about the experiment but rather background information on the subject. The background information is about Mentos reacting in Coke.

Purpose: The purpose of this experiment is to observe a variety of chemical reactions and to identify patterns in the conversion of reactants into products.

The first example of macroscopic change I observed is the color change from the combination of Starch + I2. The second example of macroscopic chemical change is the sediment formed by the combination of MgS04 and NH3. The third example is the foam from the mixture of Na2CO3+ CH3COOH

What is one way you could have increased the rate of the reaction between the Alka Seltzer and vinegar/water solutions in the beaker?

Coca-Cola has been known to cause several health issues such as diabetes, liver problems and heart disease. There has been scientific research that has proven how Coca-Cola effects the human body negatively. For example, a study shows exactly what happens to the human body after an hour of drinking coke.

The soda ash form experiment 3 was obtained. A 250 ml beaker was obtained and rinsed.
