reaction. The theoretical yield was calculated using 2-methyl-2-butanol as the limited reagent in the reaction‚ and was found to be 7.80 grams of 2-chloro-2-methylbutane. The experimental yield that was retrieved was found to be much less‚ at 1.84 grams. The percent yield was calculated to be 23.60% utilizing those values. This percent yield is quite a poor value and would be attributed to several factors in the experiment. The materials that were used to conduct this experiment

Introduction The common bean (Phaseolus vulgaris) is a fast growing plant and is used commonly in experiments due to its easy testability. It can grow in a variety of conditions and is easy to see the effects of different treatments. The idea of the treatment that we applied to our bean plants came from our class and scientific papers that help back our experiment. Examining many studies on the effects of nitrogen fertilizer on a variety of plants helped us better understand what the fertilizer was

Santo Tomas ABSTRACT The experiment was executed in order to purify compounds through recrystallization. Recrystallization is the primary used operation for purifying solid organic compounds that differ in solubility at different temperature. It is a process of dissolving the solid to be crystallized in a hot solvent mixture and then cooling the solution slowly. The objective of the experiment is to purify crude acetanilide product. At the beginning of the experiment‚ materials and solutions needed

Purpose: To find the initial velocity of a marble leaving a ramp using time‚ range‚ and background information learned in class. Equipment: The equipment used in this experiment was a toy track and ramp‚ a small marble‚ multiple Physics textbooks‚ meter sticks‚ bright-colored cardstock‚ masking tape‚ sidewalk chalk‚ plastic bag and a cloth. Procedure: Our experimental values include the height that the marble would travel‚ y= 88.1 cm‚ and our ramp angle‚ θ= 44.0°. These independent variables

Also whether any deficiencies of these minerals reduce; height‚ tiller number and root development meaning significantly low dry matter yields. The research draws attention to the fact that over the 90 day trial the Complete nutrient formula containing both nitrogen and phosphorous had the heaviest wet and dry weight with better quality florescence needed for maximum production in the

Is it normally acceptable to experiment on non-human animals to develop products and medicines that benefit human beings? New scientific research has cast grave doubt on the safety testing of hundreds of thousands of consumer products. Everyday products‚ from soft drinks to paints‚ contain numerous synthetic chemicals. Official assurances of the safety of these chemicals are based largely on animal experiments. But recent results from a consortium in America suggested such assurances may be worthless

Brenda Richardson Intro. to Psych. Chapter 6 Part 2 Loftus Experiment Elizabeth Loftus‚ a psychologist and expert on memory‚ has conducted much research on human memories‚ real and imagined‚ and how that may happen. Loftus‚ personally‚ has experienced the misinformation effect and eyewitness memory. Even though there are several experiments outlined‚ I chose the ’Lost in the Mall’ experiment as more fitting to the sex abuse testimony she gave. Participants‚ twenty-four of them‚

Objective The objective of this experiment is to compare the theoretical internal moment with the measured bending moment for a beam under various loads. Introduction and Background Theory Definition of a Beam Members that are slender and support loadings that are applied perpendicular to their longitudinal axis are called beams. Beams are important structural and mechanical elements in engineering. Beams are in general‚ long straight bars having a constant cross-sectional area‚ often classified
