Joshua McMahon IB Chemistry Matt Chase 3A 2/13/15 Finding the PH of different concentrations of orange juice. Research Question By diluting concentrated orange juice with water‚ can you significantly change the PH value? Introduction Across the world‚ it is thought and widely accepted to believe that Orange juice is the cure to many terrible diseases. However‚ this may not be true anymore. It has been said that Oranges are very high in vitamin C‚ therefore one should drink it every morning

factories‚ electrical power plants and automobiles. Two main pollutants are sulfur dioxide (SO2) and nitrogen dioxide (NO2)‚ which reacts with substances in the atmosphere‚ such as water and oxygen‚ to form acid rain. While rain water has a pH of 5.6‚ acid rain has a pH of 5 or less‚ which is acidic enough to harm plant life. Due to the reactivity of acid rain‚ the cell processes of plants are disrupted‚ and the cells die or become unable to function properly. Although this greatly damages ecosystems‚

Lab Report 3 In this lab‚ we will take a trip to the planetarium lab and will learn about Right ascension and declination‚ and altitude and zenith. After looking at the different points shown‚ we will log the altitude and zenith in the chart in our lab manual. Now we will look at the same points and label the right ascension and declination. Then we will learn about the easiest way to locate the star Polaris. As we started the first program‚ we answered a few questions to make sure we knew

have several different grades of files and buffers. That’s why we carry files with abrasive qualities from 80 grit all the way to 360 grit. Often‚ you will use more than one single grit file for a single treatment. All technicians should be able to finish a treatment using the correct and safe techniques that leave the clients nails looking good. Cutting corners and bad technique will result in a poor finish. As a technician you will use files and buffers during: Manicures‚ Pedicures‚ Gel enhancements

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

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Laboratory Report The Plasma Membrane I. Introduction The Plasma membrane is the edge of life‚ the boundary that separates the cell from its surroundings. It controls the traffic of materials in and out of the cell. (Reece‚ 2011). It is incredibly thin that is very vital in maintaining the integrity of the cell. Not only does the plasma membrane bind the other organelles‚ it also forms a dynamic structure which gives them their remarkable activity and selectivity. (Hickman‚ 2008). Diffusion
