...William Fort Mrs. Chambers Honors Biology, Period 3 31 August 2016 Alka-Seltzer Lab I. Abstract: In the lab, four Alka-Seltzer tablets were dropped into 150 mL beakers of water at four different temperatures. After the time it took for each tablet to dissolve was recorded, a clear trend was revealed within the data. This trend demonstrated that the water’s temperature corresponded with the rate of which the tablet dissolved; if the water’s temperature was warmer, the Alka-Seltzer would dissolve more quickly. The quickest trial, in 90°C water, took only 20.75 seconds for the tablet to dissolve, compared the longest, in 15°C water, which took 36.65 seconds. This data is applicable to the real world, giving this study scientific importance....

...A chemical reaction is where two or more substances come together and pops, fizzes, and in some cases explode! Alka Seltzer is a type of chemical reaction where you put water and carbon dioxide gas. Equation . When Alka-Seltzer tablets are dissolved in water, bicarbonate forms (from the sodium bicarbonate), which in turn reacts with hydrogen (from citric acid) to form water and carbon dioxide gas. “ In The bicarbonate reaction project you will find out for yourself by plopping Alkaseltzer tablets into water at different temperatures, and timing how long it ta of the bicarbonate reaction? In thiS how is temperature related to this bicarbonate reaction? In order for the reaction shown above to occur, the bicarbonate ions have to come into contact with the hydrogen ions.” Molecules in a solution are in constant motion, and are constantly colliding with one another. The hydrogen and bicarbonate ions must collide at the right angle and with enough energy for the reaction to occur. The temperature of a solution is a measure of the average motion (kinetic energy) of the molecules in the solution. The higher the temperature, the...

...Effectiveness of Antacid Tablets by Trisha Dwivdi, 2002 Abstract The purpose of this project was to figure out if antacid tablets are effective in neutralizing the human stomach. Effective was defined to mean that the tablet did not neutralize too much of the solution or too little of the solution compared to other brands. I titrated a solution that had a pH that was similar to the human stomach and tested four brands of popular antacid tablets. The four brands were Pepcid AC®, Zantac 75®, Rolaids®, and Alka Seltzer®. Rolaids® was the only brand that did not neutralize the solution. The other three antacid tablets did work and I decided that antacid tablets are effective in neutralizing the human stomach since they did not neutralize all of the stomach solution or they did not just neutralize a small amount of it. This experiment was all relative to the other tablets, because I had no background information on what defines an antacid tablet to be effective so I had to base it on the results of the other tablets. Rolaids® took an irregular amount of stomach solution compared to the other tablets to neutralize, so I based my results on this observation. Introduction The purpose of doing this project was to figure out if antacid tablets work effectively since there are many tablets out there on the market. I predicted that the antacid tablets will neutralize the stomach solution I made and therefore be effective. I worked in the Breck School Science Lab under...

...physical and chemical properties of gases and to be able to use these properties to identify these gases. PROCEDURE To start I diluted 6M HCl by pouring 6ml of distilled water in a graduated cylinder. I added drop by drop 3ml of HCl directly from the bottle. The mixture was mixed well and the diluted 9ml solution was added to the test tube. Hydrogen: I placed a place of Zn metal in the test tube with the diluted solution. I then capped the test tube with a rubber stopper with a short, straight plastic gas delivery tube through the center. The test tube was then placed into one of the wells on the well plate. The test tube had to be upright so it was necessary to wrap the tube with a piece of paper towel to hold it into place. Reaction was observed and recorded. A pipette bulb was filled with water and placed on top of the test tube’s gas delivery tube. The well plate with the test tube was placed in the tin while the gas displaced some of the water. When the water in the pipette was completely replaced by the gas I quickly removed it and placed my finger over the opening to prevent any gas from escaping. I lit a match and gently squeezed out some of the gas and observed and recorded the reaction. I then took a marker and marked 3 equal parts on the pipette. The pipette was again filled with water and placed on the gas generation tube like previously. When the bulb was 2/3 filled with gas it was removed and placed in a well with the opening done to be used later...

A chemical change involves the formation of new substances. The properties and composition of the new substances vary greatly with those of the original substance. Physical changes involve changes in physical properties, such as size, shape, and density, or changes in phase (solid to gas, liquid to solid) without undergoing a change in the composition of the substance. This experiment is where the substance in original appearance was changed into another form of substance or solution. The objective was to observe the three solutions when there was a change in chemical...

...an oil spill such as what type of oil was spilled, water temperature, weather conditions, and the impact on the surrounding coastlines. A typical oil spill clean up approach is the controlled burn called IN-SITU Burning. This is where a high volume of oil is gathered together, using the help of ships and fire resistant booms, and then is ignited in a controlled burn. IN-SITU burning is a very fragile process because there are many factors to take into consideration and each burn has to be closely monitored by professionals. Another approach to cleaning up an oil spill is mechanical recovery. This method consists of using boats, booms, skimmers, vacuums, and separators to gather spilled oil on the surface and separate it from the water. Mechanical recovery requires cooperative weather, calm seas, and lots of man power to operate the work boats and equipment used to perform these processes. Mechanical recovery is usually the first and most common line of defense when it comes to oil spills. Dispersants are also commonly used to cope with disastrous oil spills. A dispersant is an agent used to spray on oil slicks to break them up into water soluble molecules and transfer them into the water column where they are then subjected to natural process such as waves and current to further separate the oil. This technique is used to break up large oil slicks that would otherwise wash ashore where it can have a devastating effect on the environment. Dispersants are usually applied...

...Scientific Background: “Chemists have a scaled called the pH scale that is based on hydrogen ion concentration to express the acidity or basicity of solutions. The pH scale is a logarithmic scale; a change of 1 pH unit corresponds to a tenfold change in H3O+ concentration. Each change of 1 in pH scale corresponds to a change of 10 in [H3O+].”(Tro, 2015). Acids are substances that can donate a hydrogen ion in water; bases are substances that can accept a hydrogen ion or produce hydroxide ion in water. The amount of hydrogen ion donated or accepted determines the strength of the acid or base. Variables: The independent variable would be the substances being tested. The dependent variable would be the pH of each substance. The control variables are the temperature, the volume of the pH indicator and the pH indicator itself.

He was worn in August 1911, New York. Ho got a degree from New York University in English. His career started with a job running Schenley Distillers mailroom. Al though it was during the time of depression, Bernbach managed to get to the advertising department after writing an ad for one of the company’s products ("The advertising century," n.d.). Bernbach moved on to several advertising agencies till he had met Ned Doyle and Mac Dane and found DDB. At DDB, Bernbach focused on creating ads for businesses. Dane and Doyle, experts in business, combined their efforts with Bernbach's creativity to push DDb to be the 11th biggest advertising agency in America in 1976. Bernbach passed away in October 1982, only a few years after setting DDB ("The advertising century," n.d.). Bernbach had received many awards during his reputable career. He was nominated into "The Copywriters Hall of Fame" in 1964 and selected as "Man of the Year Advertising Award" in 1963, 1965 and 1966.

...ADVERTISING'S FIFTEEN JIB FOWLES* BASIC APPEALS Emotional Appeals THE NATURE OF EFFECTIVE advertisements was recognized full well by the late media philosopher Marshall McLuhan . In his Understanding Media, the first sentence of the section on advertising reads, "The continuous pressure is to create ads more and more in the image of audience motives and desires ." By giving form to people's deep-lying desires, and picturing states of being that individuals privately yearn for, advertisers have the best chance of arresting attention and affecting communication . And that is the immediate goal of advertising : to tug at our psychological shirt sleeves and slow us down long enough for a word or two about whatever is being sold . We glance at a picture of a solitary rancher at work, and "Marlboro" slips into our minds . Advertisers (I'm using the term as a shorthand for both the products' manufacturers, who bring the ambition and money to the process, and the advertising agencies, who supply the know-how) are ever more compelled to invoke consumers' drives and longings ; this is the "continuous pressure" McLuhan refers to . Over the past century, the American marketplace has grown increasingly congested as more and more products have entered into the frenzied competition after the public's dollars. The economies of other nations are quieter than ours since the volume of goods being hawked does not so greatly exceed demand . In some economies, consumer wares...
