Mentos Experiment

If the 0.2 g, 0.4 g, 0.6 g, 0.8 g, or 1 g (±0.1) of baking soda used in this experiment increases, then the volume (mL) (±0.5) of the carbon dioxide released from the decomposition will also increase.

A pattern that was found is that the water data is more consistent than the data for the juice and the seltzer. We know this because the data for the juice has a 16 second difference. The data for the seltzer came to a difference of 27 seconds. Finally the waters difference is 12 seconds, the most

Human error is easily obtained when working on an experiment with so many different solutions, time measurements, and accuracies of measurements. An easy mistake could have been made while waiting 15-20 minutes for the Carb Cutter to digest. With the time crunch in the Biology Lab, the Carb Cutter may not have been completely digested before rushing to begin the experiment. The results from the experiment showed an increase in absorbance with the Carb Cutter pill, which is not accurate because there is no way that more starch was made in the solution. Given more time for the procedure, this lab experiment may have received more accurate results.

This experiment has a goal of testing a household cleaning theory that dark sodas such as Coca Cola or Pepsi can be used as a cleaning agent and cut through dirt and grease effectively as a cleaner.  For the experiment, the researcher/writer has purchased Pepsi products, Pepsi specifically to use as the cleaning product to test.  The researcher/writer will clean six different types of messes (Food stains of ketchup and mustard on a shirt, kitchen counter grime/grease, bathroom counter soap scum, car windshield and battery corrosion on a car battery and bathroom counter/sink).  Each item will be cleaned with Pepsi and soap and water, with the soap

The purpose of the lab was to mimic the way Mendeleev placed the elements on the periodic table. Mendeleev was a Russian chemist who produced the first orderly periodic table. Frist, the way the periodic table has been classed alongside the atomic sum and the elements with related properties. Second, the objectives are observeing the physical states of common elements, and the progression of the periodic table, lastly speculate by determining the unknown elements established on the observed progression. As a group we tried to find out where the unknown elements should be placed. Finnly, the information that was given to help us with our process was the state, density, hardness, conductivity, melting point, and color.

- Diet coke made the largest Mentos fountain because it had the least amount of soda left over after the reaction.

A rougher candy surface such as, Mentos, means there are more places for bubbles to grow, or more nucleation sites. (brilliant.org) Surfactants are compounds that lower the surface tension between two liquids. (brilliant.org) Dropping Mentos in Coke is an example of a surfactant. The eruptions happen due to nucleation where the Carbon Dioxide in the soda is drawn to the Mentos. (eepybird.com) The pressure of the bottle is trapping the CO2 inside. The CO2 in the soda reacts to the sugar on the Mentos.

It is most likely almost everyone has a favorite beverage. Well beverages produce different amounts of gas. People or families who have a long history of stomach problems look into which kind of drinks produce the most gas. The question is, “How much gas does your beverage produce?” Another question is, “How does the gas produced from a beverage affect your stomach?”(Weathers 1)The hypothesis for this experiment is, “If different types of beverages release different amounts of gas then soda would release the most.” Logically it feels like soda would release the most gas since it is a carbonated beverage. In this experiment you use a variety of beverages.

A chemical change can be caused by combining two compounds, such as baking soda (NaHCO3) and vinegar (CH3COOH). The change that is taking place is because of the chemical property of reactivity. When these two compounds react CO2 is produced. In this experiment we wanted to see how much baking soda, added to 10mL of vinegar, would cause a film canister rocket to shoot the farthest. I predicted that 10mL of baking soda would shoot the farthest because it would be equal to the amount of vinegar in the canister. The independent variable in this experiment was the amount of baking soda and the dependent variable was how far the lid would shoot.

Hypothesis: Reaction 3 will create the highest exothermic reaction in the test tube this is because the chemicals are highly flammable the means they are high in exothermic relations. If we use 4 grams of zinc powder the chemical retain with the copper sulphate solution will create the highest temperature We changed the

Stoichiometry with Kitchen Chemistry By: Meena Roberts Discussion Section: Wednesday at 8:30 Objective: The purpose of the lab was to see how much carbon dioxide was produced in reaction. Procedure: Measured mass of balloon, mass of NaHCO3 and container, mass of container after NaHCO3 was removed, and mass of NaHCO3 in balloon on digital scale in grams(g).

As we all go about our day, we rush to place to place. Around us there are things for sale, people everywhere trying to make money. As we are rushing around, we all tend to get thirsty as we have a thousand things going on. In America we have dozens of choices when it comes to soft drinks, although the two most widely known are Coca-Cola and Pepsi. Many are often stuck between choosing Coke or Pepsi; even though they are slightly different in appearance, taste, and price it makes a world of difference to the customer.

Introduction: In 1866 an Austrian monk, Gregor Mendel, presented the results of painstaking experiments on the inheritance patterns of garden peas. Those results were heard, but probably not understood, by Mendel’s audience. Now, more than a century later, Mendel’s work seems elementary to modern–day geneticists, but its importance cannot be overstated. The principles generated by Mendel’s pioneering experimentation are the foundation for genetic counseling so important today to families with health disorders having a genetic basis. It’s also the framework for the modern research that is making inroads in treating diseases previously believed to be incurable. In this era of genetic engineering the

Each trial consisted of two hours of steady state cycling at 70% VO2 peak immediately followed by an all out time trial. Study A compared placebo (no caffeine), caffeine before the trial (precaf), during trial (durcaf), and cola as a replacement for a 6% CHO (carbohydrate/sugar) sports drink just before the final time trial. Study B was similar to study A, but moved up the cola drink intake to allow the athletes to consume the cola at a rate that simulated race conditions. Study B also compared decaffeinated 6% CHO cola (control), caffeinated 6% CHO cola (Caf), decaffeinated 11% CHO cola (extraCHO), and caffeinated 11% CHO (Coke). This allowed determination of whether effects were from caffeine, increased sugar content, or some combination.

Question 6: You look in the refrigerator and find an orange drink you had forgotten was there. The drink now has an off-taste and it bubbles. What is the most likely explanation for the changes in the drink?
