Alka-Seltzer Rockets Instructor: Mr. Thompson Due 4/1/16 Science Research Jamal Matthews Jeremy Alpert Sophia Tannenbaum Abstract Alka-Seltzer® is a tablet that can be taken to relieve stomach pain from indigestion. Our experiment was designed to test the hypothesis that if the amount of Alka-Seltzer® increased, then the time it would take for the cap to pop off the film canister would decrease. In our experiment, we changed the amount of Alka-Seltzer® from zero tablets, to one quarter tablet, to one half tablet, and then to one full tablet. We placed the Alka-Seltzer® tablet into a film canister, poured ten milliliters of water into the canister and then capped the …show more content…
The bicarbonate then reacts with the hydrogen from the citric acid, and this reaction makes water and carbon dioxide. By mixing water with the Alka-Seltzer® tablet, the whole reaction process is started, and that process ultimately results in bubbles of carbon dioxide gas being given off. When the film canister is capped, this gas that is being given off is suddenly contained inside an enclosed space. The pressure inside the canister then rises until there is too much force for the lid to stay sealed (attached to the canister). The built up pressure is strong enough, and exerts enough force to push the canister quickly into the air, forming the …show more content…
Thrust is able to happen because of Newton’s third law of motion: for every action, there is an equal and opposite reaction. In a rocket that is going into space, there is gas that is pushed out of the engine in one direction, and the thrust is applied in the other direction, to lift the rocket off the ground and up into the sky. Similarly, in an Alka-Seltzer® rocket the thrust is provided by the gas (carbon dioxide), but because the gas is enclosed, it is not able to escape. When the gas finally does escape, it functions as the counter-force, and enables the canister to separate from the cap and fly into the
Alka-Seltzer is a medical drug that serves as a pain reliever and for heartburn. (Rowland) It may also be used for indigestion, body aches, and different types of pain. (Rowland)You should completely dissolve the tablet in a glass of water before taking them. (Rowland)Next it will go through a chemical reaction that produces lots of carbon dioxide. (Rowland) For this reaction to occur the tablet must come in contact with hydrogen.

A common over-the-counter medication for symptoms such as headache, stomach ache, and heart burn is Alka-Seltzer tablets.1 One of three ingredients found in the tablets is acetyl salicylic acid (C8H12O4) to relief head ache pains. The other two components are sodium bicarbonate (NaHCO3) and citric acid (C6H8O7) which are utilized under the acid-base chemistry rule in order to produce the fizzing sensation needed to produce excess CO2 to aid in heartburn and stomach aches.1 The Brønsted-Lowery Acid-Base Rule simply states properties of both types of substances and how they will react with when added to a solution. A base will accept a proton donation while an acid will donate the proton.2 Utilizing all of this information an experiment was conducted
I have been a snob. It is quite soft, but solid. It reacts with hydrochloric acid. like this 2 CaCO3 + 2 HCl â’ CO2 + CaCl2 + H2O. producing carbon dioxide, which is what we measured in the experiment. There are different factors affecting the rate of this reaction, such.
After reading more about Red Bull, I began to notice their success as a company. Their strengths include their marketing and distribution power. Since the beginning, Red Bull has always paid close attention to their branding strategies. “The importance Red Bull gave to marketing was obvious from the fact that it spent over 30% of its annual turnover on marketing, while competitor’s only spent 10%” reported the Amity Research Center. Along with branding, differentiation was used with the can sleek style and creative logo. This was nothing like the world has ever seen, ultimately creating a unique brand for themselves.
The experiment, focuses on the effects of acidic drinks on teeth. In this experiment, the scientist is trying to answer which liquids; Arnold Palmer, Coffee, Coca Cola, V8 Splash Tropical Blend, and crest pro-health toothpaste, affect your tooth enamel the most. The Independent Variable are four ounces of each liquid, and the dependent variable is the staining of teeth. The Constants are the toothpaste, toothbrush, the amount of time the eggs stay in the liquid, and the type of eggs used. The units used while measuring the effect of liquids on teeth is ounces.
A bottle rocket is a type of model rocket using water as its reaction mass. They are usually made with an empty two-liter plastic soda bottle. The water is used to pressurize air in the bottle for launching. Which is released rapidly through an opening as it tries to escape. A rocket is subjected to the forces of thrust, lift, drag, and gravity just like airplanes. Thrust is the force that causes
In undertaking the experiment, the hypothesis “if the number of Alka Seltzer tablets reacted increases, then the maximum rate of reaction will increase,” was formed. When graphing the relationship between the maximum rate of reaction and the number of Alka Seltzer tablets reacting, Graph 7 produced a line of best fit with a constant increasing slope that passed through the origin (0,0). This is characteristic of linear graphs, which have the general equation, y=mx, where m is the slope, a constant term, and y and x are changing variables that are directly proportional (i.e. y ∝x). Hence, it can be deduced that Graph 7 is a linear graph, and that there is a linear relationship between the maximum rate of reaction and the number of Alka Seltzer tablets, where they are directly proportional. That is, as the number of Alka Seltzer tablets increased, the maximum rate of reaction increased, supporting the hypothesis. As the true value of the maximum rate of reaction per Alka Seltzer tablet was not known, and a value for comparison was unavailable, the accuracy of the results could not be determined. However, due to the scatter in Graphs 2 to 7, it was evident that the results had low precision. In future, repeating the experiment using different and/or new apparatus will aid in detecting systematic errors and improve the accuracy and validity of the results.
This hot gas is pushed out through the back and it makes the rocket move forward. This is using Newton's third law of
“Powder” is a story about an adolescent boy and his father on a ski trip, whose relationship is not always apparent between the two. The standard role of the father and son has been reversed in this story. The adult in the relationship is not always who it expects to be; in this situation, the boy is more like a man, and the father is more like the boy. There is a reflection of a modern day “broken” home situation between the parents, who seem to be on the verge of a divorce. They story is told from a first-person perspective of the boy. This way we see the boy’s thoughts and feelings about his emotional position. The father has promised the mother that he will have the son back on time for Christmas Eve dinner. Keeping this promise is important for the father because he seems to want to prove himself to the mother.
(Antacids help neutralize stomach acidity, which can cause heartburn.)” (Science Buddies, Carbonation Countdown: The Effect of Temperature on Reaction Time). To take the Alka-Seltzer tablet you have to dissolve it in water causing a chemical reaction to form and the whole solution begins to fizz. The fizz occurs
The rate at which Alka-Seltzer tablets reacts with water Statement of problem The aim of the experiment is to find out the rate at which Alka-Seltzer tablets react with water. The input variable that I will change is temperature. The output variable will be measured by the time it takes for the Alka-Seltzer tablets to dissolve.

This along with the lighter construction of a two-stroke makes it the preferred motor used in small vehicles and tools (Two Stroke Engine). A two-stroke engine is operated by first drawing the mixture of fuel and air into the chamber by the vacuum caused by the upward stroke of the piston. During the downward piston stroke, the poppet valve is forced closed due to the increased pressure within the chamber. The mixture is compressed in the chamber throughout the stroke. As the stroke ends, the intake port is exposed allowing the mixture to escape into the main cylinder, expelling the exhaust gasses in the process and some of the fuel mixture as well. Momentum then causes the piston to rise, compressing the mixture as another stroke is beginning. Once the stroke reaches its peak, the spark plug will ignite the mixture causing the fuel to expand driving the piston down thus completing the cycle while additionally initiating a new
