    a beginning reagent to dehydrate and possibly form 3-methylcyclohexene‚ 1-methylcyclohexene‚ or methylenecyclohexane. Drierite® (Calcium Sulfate) was used as a drying agent to help break the alcohol and hydrogen groups from the carbons. Concentrated phosphoric acid was used as a catalyst to help move the reaction towards the products motioned above. To determine the successfulness of the experiment and the amount of product(s) recovered‚ IR spectroscopy‚ Gas Chromatography and percent yield calculations

This means 0.15g of liver for each percent of catalyze concentration. Overall I need 2.25g of chicken liver because I will conduct each percent with 3 trials. Measure 0.15g of chicken liver for 1% catalyzes concentration using electronic balance and a sterile weigh boat Grind the chicken liver until little to no clumps are visible

    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

    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

    Magnesium Oxide Lab Purpose: To determine the composition by mass of magnesium oxide‚ the percentage composition‚ and the percentage yield. Hypothesis: The law of definite proportions states that a chemical compound always contains the same amount of proportions of elements by mass. Based on the law of definite proportions‚ the percentage composition of magnesium oxide should be 60.3% magnesium and 39.7% oxygen. Prediction: Based on the law of definite proportions‚ the percentage composition of magnesium

    Wave Nature of Light Objective: The purpose of this lab is to investigate interference‚ otherwise known as the diffraction of light. A beam of light acts a wave‚ and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges‚ allowing light to enter an area of shadow. When waves are superposed‚ they reinforce each other when crests are in phase and cancel out when they are not in phase
