    Spokane‚ Washington. Viney and Fenton (1998) defined the term electrophoresis as‚ “the migration of charged particles through a static medium under the action of an applied electric field (p. 576). Just from this definition‚ it is clear that numerous physics concepts can be used to help explain why electrophoresis works. First‚ I will discuss charge and electric fields and how these principles are utilized in gel electrophoresis. This will be followed by a

    and therefore the crude solid must be purified. This purified product is what is later put into the analgesic. In this experiment‚ the procedures that are important are vacuum filtration and recrystallization which are both used to obtain the Acetaminophen product. When collecting products‚ it is important to know how much product is left and what is lost through the experiment. To do this‚ the balanced equation will be looked at and then the theoretical yield will be calculated. In order to calculate

    Conclusion: Category 1: Momentum was found that after the collision was less than before the collision by 10%. This was not what has been expected‚ so the difference was fairly significant. This happened because of friction‚ when the two pucks collided‚ they have lost a bit of their momentum‚ so the momentum after the collision differed. Kinetic energy differed more than what was expected‚ it was significantly less after the collision‚ the difference before and after the collision was 63.7%‚

    water‚ it will affect the swimming speed of the paramecium. The various students groups have individual experiment of how dose NaCl affect swimming speed of Paramecium‚ but the experiment did not show the result clearly to students. Therefore‚ after they finish the presentation‚ most of the students want to find out the chemical NaCl increases swim speed of Paramecium. Experiment Design The experiment prediction is if we add 4mL of Paramecium to 25mL of 0.2M NaCl and 225mL of Dryl’s solution‚ then Paramecium
