12 Abstract: The purpose of this experiment is to determine how a beam deflects with load and compare the experimental values to the values calculated from the simple formula and exact formula. We take three different eccentricities 75 mm‚ 55 mm‚ 35 mm and gradually apply load to them. Taking readings and making graphs to explain the outcome. This kind of experiment is helpful in construction of railways and grids. 1.0 Introduction: The experiment is done to find the connection between the

Objective: The purpose of the lab is to learn filtering techniques. Specifically‚ to form and filter a calcium carbonate precipitate using a Buchner funnel. Procedure: a.) Prepared a mixture of .5 M calcium nitrate (45 mL) and .01 M sodium carbonate by combining and stirring the two liquids in a beaker. Allow the mixture to stand. b.) Prepare the filtration assembly. The assembly consists of a tapered flask with a buchner funnel inserted in the top. The funnel has a rubber stopper attached

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

(3 points) Score 1. How do you calculate magnification on a microscope? Answer: The shortest lens is the scanning objective; you use it to locate the object on the slide. The medium-length lens is the low-power objective. The longest lens is the high-power objective. Multiplying the power of the eyepiece

Aseptic technique Michele Pearson‚ Leah Christine Silver‚ and William Jarvis Purpose Aseptic technique is employed to maximize and maintain asepsis‚ the absence of pathogenic organisms‚ in the clinical setting. The goals of aseptic technique are to protect the patient from infection and to prevent the spread of pathogens. Often‚ practices that clean (remove dirt and other impurities)‚ sanitize (reduce the number of microorganisms to safe levels)‚ or disinfect (remove most microorganisms but not

Full Lab Report Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid‚ potassium acid phtalate (HKC8H4O4‚ abbreviated KHP). This will be accomplished using the titration

If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are
