The purpose of our experiment is to test animal behavior and reactions to a change in environment. Our guiding question is, “Why do living organisms respond to environmental factors?” This is basically a question that is asking why living things will react a certain way to environmental changes. The task to answer this question is to experiment with changing environmental factors with pill bugs.
Joy Morounfolu Lab Partner: Ruth Bochung Chem-C 103 Section 1455 10 October 2017 What Is the Percent by Mass of NaHCO3 in Alka-Seltzer® Tablets? Introduction Ever wonder about the chemical makeup of tablets that people take for pain relief? Before a tablet can be successfully made, the limiting and excess reactants must be considered. The limiting reactant will affect the amount of the product that can be made. Another reason why the starting reactants must be determined carefully is to make reduce the amount of the reactant in excess so that reactants are not wasted. This experiment uses an Alka-Seltzer tablet. Alka-Seltzer dissolves in water and is an antacid and a pain reliever1. The Alka-Seltzer tablet has many uses such as relief of headaches, ingestion, heart burns, or even upset stomachs2. The active ingredients in an Alka-Seltzer tablet is aspirin, also known as acetyl-salicylic acid (C8H12O4), citric acid (C6H8O7), and sodium bicarbonate (NaHCO3)2. The aspirin in the Alka-Seltzer tablet helps with pain relief. Because of the acid-base chemistry (Brønsted-Lowry), citric acid and sodium bicarbonate produce O2, which makes the tablet fizz when it is dropped in liquid. The Brønsted-Lowry theory shows how the Brønsted-Lowry acid donates a hydrogen ion while the Brønsted-Lowry base accepts the hydrogen ions3. The remaining NaHCO3 that is in excess post reaction with the citric acid is what is used to neutralize stomach acid which helps relief heart burn2. The problem in
Materials -Twelve sow bugs -Bisected grapes -Chunks of potato -Decaying leaves -Pinch of sow bug food This information would suggest that the sow bugs were not especially interested in food at the time the experiment took place.
4. Materials: Connected Chambers At Least 10 Isopods Warm Water Plastic Water Holder Small Paint Brush Conclusion/Discussion: The important procedures of this experiment was to observe the pill bugs and determine whether they prefer a certain environment over another. The results and data of the lab show and prove that the isopods prefered the room temperature environment over the warm environment. The hypothesis is accepted because it states that if the isopods were given a choice of a room temperature environment or a warm environment, the isopods will choose the room temperature environment, and the isopods chose the room temperature environment. The control of this experiment was the room temperature chamber.
Unfortunately, this topic affects a lot of people, taking away their freedoms. “Among them are… Zondenta McCarter, a sixty six year old woman, a first offender, poor and illiterate, suffering from diabetes, described as naive, trusting and childlike… sentenced to 8 years in prison.” (Schlosser, 4) The author explains that just because she used something once that she’s a dangerous criminal, but if she wasn’t apart of violent crimes she shouldn’t be getting such a harsh sentence. Mark Bennett interviewed some of the criminals, “18 were pill smurfers… single mothers… yet all of them face… sixty to 120 months.” (Bennett, 1-2) None of them were violent crimes, sadly, they get sentences that not only affect them but their families and the world.
The acetaminophen tablets from the Well at Walgreens brand showed a degradation of percent label claim of acetaminophen characterized by a R¬2 value of 0.4728 on a downward sloping treadline. The control percent label was found to be 105.3%. The percentages for weeks 2, 4, 6, and 8 were as
The OTC medication chosen is NiteTime Server, this is a genetic brand pain and fever reliever. It tells what symptoms it relieves such as headache, fever, sour throat, minor aches and pains. The product has as its active ingredient both 650 mg of Acetaminophen for pain reduction and fever reducer. It also has 20 mg of Dextromethorphan HBr which is a cough suppressant. The label clearly defines what the active ingredients do as well as a warning label. Some of the warnings are that taking large doses of Acetaminophen can be sever on the liver. The warnings also mention about not consuming three or more alcoholic beverages with this medication. If a sever sore throat last longer than two days the user is advised to call their doctor. The label
Results and Discussion Goodsense cetirizine tablets were observed to degrade the slowest out of the three brands: Goodsense, Zertec, and Rising. The cetirizine in Goodsense pills was observed to drop to 85.9% label claim after seven weeks of exposure in the environmental chamber (Figure 2). Outliners include data points that are
Introduction: The purpose of the experiment was to compare antacids by the amounts acid they neutralize to find the most effective antacid. Finding the most effective antacid is important because it will help others by allowing them to choose the best product for their heartburn. Titration is the process of which the unknown solutions concentration reacts with a known solution concentration. During the experiment, titration was used to calculate the moles of HCl neutralized by the antacid in this case was gelusil, by knowing the moles of HCl initially added to the flask and moles of HCl neutralized by the NaOH.
Introduction: Since 1979, the Food and Drug Administration (FDA) has required that all prescription drugs have a shelf life (or expiration date) indicated directly on the container label. Similar requirements are in place in the European Union and around the world (1).
These Tests Identify The Causes Of Your Allergy Symptoms If you have problems with allergies, the triggers for your symptoms may be obvious. If you get watery eyes and a scratchy throat every time you're around a cat, you can be fairly certain you're allergic to cats. If you have frequent
I just stepped in what I think is a bag that used to contain some sort of narcotic and a napkin with vomit all over it. I could tell it was a puke-soaked cloth from the way my shoe slightly sunk into the ground and made a noise similar to that of dipping a spoon into a pot of macaroni and cheese. I knew it was a bag that used to contain drugs because this is a California Cchinatown, a.k.a. the land of conspicuous drug deals. I remember I used to see “transactions” all the time right after we moved here. One time, around four years ago, when I was eight, I saw a black man wearing a wifebeater and saggy jeans trade brown paper bags with a Vietnamese man wearing the same thing. They looked around cautiously, got really close to each other and

"Asthma is a common chronic disease worldwide and affects approximately 24 Aspirin induce bronchospasms prevalence is 0.6 - 44% overall and 21.1% in asthmatic patients and 29.9 % in patients with a previous incident of aspirin induced bronchospasm. 5 The wide range is due to patients without a history of asthma or Aspirin induced asthma being less prone while patients with a history if asthma being more apt to aspirin induced bronchospasms especially patients with asthma and nasal polyps.5 NSAIDs like ibuprofen, naproxen, and diclofenac (strong cyclooxygenase inhibitors) have reported cross sensitivities in aspirin intolerant patients of 98%, 100%, 93% respectively.5 However, low inhibitors ( acetaminophen) and non-inhibitors( meloxicam) of cyclooxygenase 1 are better tolerated in patients with cross sensitivity6 ;and only tend to induce bronchospasms at
