experimentation. Following the use of the indicator‚ a 50 mL burette with 50 mL of sodium hydroxide (NaOH) was used to drip minute amounts of concentration to each of the three 25 mL of HCl that contained the dissolved Gelusil antacid tablet. The first beaker turned slightly pink with 7.5 mL of NaOH. It contained 0.018 moles of HCl. The second beaker also showcased slight hints of peak with 7.0 mL of NaOH. It contained 0.020 moles of HCl. The third beaker‚ which was not averaged into the experiment‚ turned

Collisions in Two Dimensions Abstract: This lab was conducted to investigate the theories of conservation of momentum and kinetic energy in different types of 2D collisions. In order to do this‚ both an elastic and inelastic collision was conducted on an air table with pucks. A video was taken and analyzed to determine velocity‚ allowing for future finding of momentum and kinetic energy values. By finding these‚ it was possible to determine which kind of collision took place. With low values of

collected in lab #1 shows the relationship of surface areand volume in the artificial cells to the diffusion rate using the phenolphthalein-NaOH agar and the HCl solution. Lab #2 was a model of diffusion and osmosis‚ in which we filled the model cells with different solutions and determined the rate of diffusion. In lab #3‚ the results demonstrated the interactions between selectively permeable membranes‚ water‚ and solutes and how they are important in cellular and organismal functions. In lab #1‚ the

known as S. typhimurium‚ is a Gram-negative‚ rod-shaped‚ flagellated‚ facultative anaerobe microorganism. S. typhimurium can be found in animal feces and raw contaminated foods such as poultry‚ beefs‚ sea foods‚ tainted fruits and vegetables (3‚ 5). Some of the vectors of S .typhimurium are birds‚ reptiles‚ and aquatic vertebrates (5). After the consumption of the bacterium‚ S. typhimurium is found living and growing in the mammalian GI tract.

Beer’s Law And Calorimetry Beer’s Law And Calorimetry Adriane Bellard Ocean County College Beer’s Law is also referred to as the Beer- Lambert law or the Bouguer- Beer Law. The principle is based on an electromagnetic radiation that is passed through a sample‚ wavelength is detected by the sample. As a result strength of transmitted light is gradually reduced. The measurement of the reduced strength of radiation is supported by the spectrophotometer. Based on Beer’s Law the strength

This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating

The 1980s: A time of the Yuppies‚ Brat Packs‚ and Rock and Roll In the great words of Ferris Bueller‚ “Life moves pretty fast. You don’t stop and look around once in awhile‚ you could miss it” ; the infamous 80s went by fast‚ but with the invention of the internet in the 80s‚ we can reminisce and unveil the distinct fashion‚ arts and music of the decade. Fashion from the 1960s/70s evolved into the 1980s. America’s wealth prospered‚ a decade consisting of traditionalism‚ luxury‚ and consumerism
