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

tissue sample for examination and referred the patient to a gastroenterologist for a barium xray and colonoscopy. While utilizing the methods stated above‚ the bacterium found was a facultative anaerobe due to the Gram Negative Rods‚ fermentation‚ and the production of indole. The specific Gram Negative Enteric Bacilli was Shigella dysenteriae. There are many reasons for knowing how to control bacterial growth as well as such as antimicrobial drugs‚ which assist the body’s defenses against pathogens.

Title: Staining Introduction: Microorganisms are small and colorless‚ invisible to unaided eyes. When observing them under microscopes‚ we use various methods to make microbes apparent. One of the most important methods is staining. Staining techniques play an essential role in the studying of microorganisms; they help to reveal characteristics of microbes‚ such as their morphologies‚ sizes‚ arrangements‚ chemical components and many more. The purposes of the experiments are to be

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

Investigation Investigate the amount of heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid

LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances
