The science project I am going to conduct contains me trying to find which amount of surface area of an Alka-Seltzer tablet gives off the most gas bubbles once I drop the tablet into water. The Alka-Seltzer tablets will be crushed into different equal surface areas ranging from crushed to cut in halves or in quarters. After that I will then add the Alka-Seltzer tablets inside of the balloon.(¨Bubbles, Gas, and Balloons¨) I am going to measure the amount of gas bubbles the Alka-Seltzer tablet gives off by attaching a balloon to the top of my Erlenmeyer flask and then measure the circumference.
ALKA-SELTZER The Alka-Seltzer tablet is a medicine tablet taken by people as an antiacid to help calm down stomach acids which can lead to heartburn.(¨Carbonation Countdown¨) The Alka-Seltzer tablet is also used as a pain reliever. The pain reliever has aspirin and citric acid in it while the antiacid also has citric acid but instead of aspirin the antiacid has sodium bicarbonate, which is also known as baking soda. The Alka-Seltzer tablet was first created by a chemist working for the company Miles Laboratory named Joseph Maurice Treener. (¨Who invented Alka Seltzer¨) Treener discovered that if he added sodium bicarbonate to aspirin it would create a tablet that works wonders to

(¨World Book Encyclopedia¨) Over the period of the rest of the 1800s, chemists isolated countless organic substances and discovered that these organic compounds usually consist of carbon conbined with nitrogen, oxygen, and hydrogen molecules in different proportions. Because of this, in the mid-1800s chemists started to include ideas about molecular structures in their hypotheses. Chemists then later on developed a theory called the valence theory to explain how different atoms conbine to create
Kool-aid was invented by a man named Edwin Perkins He was born in the state of Iowa but he eventually went to live in Nebraska. At about 1927 he invented Kool-aid He was inspired by the drink Fruit smack, but because he wanted to lower the cost of shipping he removed all fluids from the drink. This dry powder eventually became Kool-aid. However Kool-aid did not always go by the same name It was originally Kool-Ade but because Ade refers to juice he had to change it tho the name it has today. Eventually Kool-aid got their own mascot the cool-aid man (He often broke through walls), They also had a comic with 7 issues, along with the Atari 2600 came the “Adventures of Kool-aid Man”. Kool-aid can still be bought today and has manny flavors
(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
Random and systematic errors are both factors that can affect the reliability and accuracy of the results respectively. As all the graphs contained outliers, and hence, scatter, this indicates that random errors were present. Such errors may result from the inconsistent masses of the Alka Seltzer tablets. As these tablets were cut manually with a knife, it is unlikely that the mass of each half of an Alka Seltzer tablet would be the same. Thus, when using the tablets to react with HCl, the true number of tablets reacting would have not been the same as the number denoted for the trial, and with each repeated trial for the same number of tablets reacting, the reacting mass and ratio would have not been inconsistent. Consequently, the
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
Regarding the densities of Coke and Diet Coke, I believed that the density of coke would be greater than the density of Diet Coke. Because the content of Coke contains more sugar than Diet Coke, it would contain more mass and since density is mass dependent, Coke would be denser than Diet Coke. From the results of the experiment, there was a slight difference between the densities of Coke and Diet Coke. The measurements obtained from the pipette and the graduated cylinder demonstrated that Coke is denser than Diet Coke while Diet Coke was shown to be denser than Coke using the burette. With the pipette, the average density of Coke is 1.02 and the average density of Diet Coke is 0.99. With the graduated cylinder, the average density is 0.976968 and the average density of Diet Coke is 0.95. With the burette, the average density of Coke is 0.99 and the average density of Diet Coke is 1.0. Among the three instruments, the most precise was the graduated cylinder and the most accurate was the volumetric pipette. Since density is defined as mass/volume, changing the volume of Coke or Diet Coke would have changed.
The Niitsitapi (also called Blackfoot Indians), reside in the Great Plains of Montana as well as Alberta and Saskatchewan located in Canada. Only one of the Niitsitapi tribes are named Siksika, also known as Blackfoot.
Aspirin contains the substance acetylsalicylic acid (ASA), which can relieve inflammation, fever, pain, and known as a “blood thinner”. Aspirin was not officially trademarked until March 6, 1899 when the Imperial Office of Berlin made it official. It has been used for the last 110 years, but its natural form, salicylic acid has been around for thousands by Egyptians, Greeks, and Romans. Aspirin is available in over 80 countries and known as the best non-prescription drug. The most common use of aspirin is to cure headaches and use it as a pain reliever, but aspirin is known to prevent heart attack and strokes. It was first proposed in 1940, but wasn’t confirmed until 1970 when doctors would recommend taking aspirin daily [1].
I shall be measuring how much gas is given off. This will be done by measuring the amount of froth on the surface of the liquid. The oxygen released is collected in the form of these bubbles. The equation for the reaction is: (catalase) [IMAGE] H2O2 2H2O + O2 (hydrogen peroxide) (2 part water) (oxygen) I will change the concentration of H2O2 and O2 (making sure the volume stay the same, when one part of a H2O2 particle is taken, an O2 particle is added. Prediction
Displacement is a method used to find density that is associated with the Archimedes’ principle, which states that when an object is submerged in a liquid, it will displace its’ volume. In this experiment, displacement was used to find the volume of a group of beads, which were small, multicolored, smooth, and round with a large hole in the centers. After finding the volume that the beads displaced, the density was calculated by taking the mass of the beads and dividing it by the volume of the beads. Displacement was used for four trials for each individual, which summed up to twelve times for the group.
This may sound easy but can be very tricky at some times. Flattening out gum can be very hard comparing different gum types. Some types of gum are very pliable and some are not. Such as Trident gum it is not very pliable but double bubble very pliable when flattening out the gum. Another thing you have to care for when flattening is making sure it is flat enough but not too flat. You cannot make a paper thin gum and expect to make a bubble out of it. The last thing that could corrupt your experiment is starting to chew your gum again before blowing your bubble,you do not want to start chewing your bubble gum because then you will have to start over from the first
* Count the number of bubbles seen in 1 minute which is a way of

Heineken’s follows a differentiation business strategy and multi-domestic strategy. Heineken gains a competitive advantage by distinguishing their products by creating Premium Light beer line, portable draught beer system (DraughtKeg), and redesigning their bottles. Heineken Premium Light attracted customers without taking sales away from their other beer selection. The decision regarding the launch of their new product was to raise brand awareness in the U.S. market and react to changes in the growing global market. Major source of Heineken’s revenue comes from their subsidiaries. The mergers and acquisitions of the local beer brands in niche markets such as the recent five brewers in Nigeria have provided a gain in the local market share. Using a multi-domestic strategy, a major source of revenue results from their subsidiaries and they have had an increase in sales since 2006.
For example, a study from the Voice Institute of New York found that drinking alkaline water with a pH of 8.8 can help deactivate pepsin. Pepsin is the main enzyme that causes acid reflux. Another study published in the Shanghai Journal of Preventive Medicine suggests that drinking alkaline water may be beneficial for people who suffer from high blood pressure, diabetes, and high cholesterol. Meanwhile, the study from the University of Alberta concludes, “it would be prudent to consider an alkaline diet to reduce morbidity and mortality of chronic disease that are plaguing our aging
