Procedure: • Gather a test group of 15 people who have not done any strenuous activity in previous hour, also no caffeine for 8 hours (to get resting heart rate). • Calculate the resting heart rate of the fifteen people, and record. • Take heart rate after twenty minutes have passed, and record. • Collect this data on three different test groups using the three variables of caffeinated beverage. Previous Research: The effects on caffeine have not been a closely researched topic in the scientific world.
Acid Base Titration Purpose: The purpose is to calculate the molarity of a NaOH solution by titrating the base with 5mL of standard HCl solution in each trial. By adding the base with unknown molarity to the acid with 0.10M the molarity of NaOH can be calculated. The base, NaOH, helps bring the pH of the acid, HCl, closer to seven, which neutralizes it. When using the buret the amount of NaOH used is able to be determined. Then by writing a balanced chemical equation and using the titration formula, Nb+Ma+Va=Na+MbVb , the molarity is able to be determined.
These consequences affect all the organ systems in the body. (Carol Mattson Porth, Glenn Matfin 2009) Cause: The presented patient scenario along with the information given indicate that Ms. Smith suffers from ARF that is caused by severe dehydration. This severe dehydration in turn produces Prerenal acute renal failure due to decrease renal blood flow and decrease glomerular perfusion and filtration. Based on the above patient diagnosis the labs would be as follows: K or potassium will be elevated to more than the normal ratio: K >5 Creatinine elevated: >2 Bun elevated: >20 Urea & sulfate will be elevated Sodium levels will be normal or low Calcium will be low & phosphate will be high. Hgb will be low: <12 Urinalysis: patient has low urine output and urine will have low specific gravity.
Given the results, we determined our experimental methods were effective in determining the content of calcium carbonate in the antacid sample. In the future, we will implement a centralized time keeping procedure to ensure increased efficacy of our experimental techniques. Introduction Heartburn condition, also known as pyrosis, non-cardiac chest pain or acid reflux, is a predominant ailment in our society. The condition causes painful burning sensation in the esophagus, and is usually associated with regurgitation of gastric acid. This is mainly due to the premature opening of the lower esophageal sphincter between the esophagus and the stomach.
It increases chances of peptic ulcers and gastric adenocarcinoma. (Suzanne C. Smeltzer & Brenda G. Bare, 2004) The textbook mentions that a simple blood test can detect H. pylori. If you test positive the treatment of choice is multiple antibiotics, a proton pump inhibitor and H2 blockers for fourteen days. Resistance to H. pylori to metronidazole and clarithomycin is on the rise. The article explains in depth the different tests for H. pylori such as another blood test to recheck needs to be done at least six months after treatment to allow antibodies titers to decrease.
LIQUID-LIQUID EXTRACTION OF BENZOIC ACID J Wright Organic Chem Lab 1 Tuesday 1:40-5 Ian Stubbs LIQUID-LIQUID EXTRACTION OF BENZOIC ACID PURPOSE: The purpose of this experiment was to extract benzoic acid from an aqueous of benzoic acid using methylene chloride, use liquid-liquid extraction to calculate the distribution coefficient of benzoic acid and to determine whether a single extraction or multiple extractions are more efficient. Add in the table of physical constants. See the attachment for the lab format. PROCEDURE: Gather a two stock solution that includes; 0.02M of sodium hydroxide (NaOH) aqueous solution and 0.02M of benzoic acid aqueous solution. For a single extraction, use a 50mL graduated cylinder and measure out 50mL of the benzoic acid solution into a 125mL separatory funnel.
A muscle called the urinary sphincter, located at the junction of the bladder and the urethra, must relax at the same time the bladder contracts to expel urine. It can be also said as Cystitis; UTI. Causes The bacterial strains that cause UTIs include: 1. Escherichia (E.) coli are responsible for most uncomplicated cystitis cases in women, especially in younger women. E. coli is generally a harmless microorganism originating in the intestines.

The older son is underweight and has difficulty gaining weight, he does not visit the doctor and treats his allergy and sinus problems with over the counter products. The father goes to the doctors every 3 months for hypertension follow-up. He is prescribed 3 separate medications for hypertension. Today his blood pressure was 134/106. The father is suffering from
At this point the volume of base used to neutralized the acid can be determined. Phenolphthalein is the indicator which is colorless in an acid but changes to a faint and permanent pink color in base. The purpose of this experiment is to prepare a sample for titration with a base, become familiar with a buret while using proper titration technique in reaching an end point. Hypothesis : If I titrate a base of known concentration with an acid of unknown concentration then I can determine the concentration can be calculated because of the titration calculation. Materials : • Vinegar • Two small beakers (150mL) • 250-mL Erlenmeyer flask • 10-mL graduated cylinder • 50-mL buret • Buret clamp • Small funnel • M NaOH Hazards : • Chemical spill • Broken glass
