    1. The color of Max’s urine tells Tracy what the concentration is because the darker the urine color, the more concentrated it is. The clearer it is, the less concentrated it is. Urine pigment correlates with specific gravity because the more concentrated (darker) a urine sample is, the higher the specific gravity will be as well. 2. Based on the urine color and specific gravity, Tracey is able to conclude Max’s hydration status during the different recorded stages. Before he exercises, Max’s…

    A graduated cylinder was used to measure 200mL of distilled water into an Erlenmeyer flask and then 40mL of 0.6 M NaOH was added to the distilled water in the flask. The flask was then plugged with a rubber stopper and shook in order to mix the solution. A buret was then washed, rinsed with distilled water, and then 5 mL of the NaOH diluted solution. After the cleansing of the buret, it was then filled up with the NaOH diluted solution. The dilution of the solution was calculated to find the…

    • 4 Pages

    A different type of Japanese bamboo had been studied by Phong et al. (2012). Moso bamboo was harvested and processed using several methods to obtain the fiber. In alkali extraction method, the bamboo was cut into thin slabs with length and thickness of 25 cm and 3 mm, respectively. The slabs were immersed in different concentration NaOH solution (1%, 2%, 3%) at 70 ⁰C for 10 h. This study showed that only 1% NaOH resulted in higher mechanical properties. The roller looser was then used to produce…

    Conclusion: I predicted that liquid A was glycerine due to a calculated density of 1.38 g/mL. However I was wrong the actual density of liquid A was 1.38 g/mL and the substance was actually corn syrup. Therefore the percent of error for the density of liquid is 1%. For liquid B I had predicted that its substance would be Glycerine due to the calculated density of 1.19 g/mL. I was incorrect for the density of liquid B which was actually 1.26 g/mL, but because the calculated and actual densities…
