Nahom Assefa CHM-201 General Chemistry and Laboratory I Laboratory 8. Spectroscopy Purpose: Spectroscopy is the study of matter interacting with electro-magnetic radiation (e.g. Light). In this lab‚ we will separate some light sources in to constituent colors and find out the wavelength of some atomic emissions. We will also try to compare the line spectra found from gas discharge tubes and flame emissions. Finally‚ we will measure

Overview of formulas Formulas are equations that perform calculations on values in your worksheet. A formula starts with an equal sign (=). For example‚ the following formula multiplies 2 by 3 and then adds 5 to the result. =5+2*3 A formula can also contain any or all of the following: functions‚ references‚ operators‚ and constants. Parts of a formula Functions: The PI() function returns the value of pi: 3.142... References: A2 returns the value in cell A2. Constants: Numbers or text

Format of a Laboratory Report Your laboratory report should be divided into the following sections. Be sure to label each section! I. Introduction A brief statement of the purpose of the experiment. This is also a good place to show relevant structures and chemical equations. II. Experimental Procedure A brief outline of the experimental procedure. Be particular about reporting the amounts of materials used and any modifications made to the original procedure (avoid simply

A. Water boils at 100°C at sea level. If the water in this experiment did not boil at 100°C‚ what could be the reason? The reason why water did not boil at 100°C could be because we are not at sea level; the pressure could be lower. B. While heating two different samples of water at sea level‚ one boils at 102°C and one boils at 99.2°C. Calculate the percent error for each sample from the theoretical 100.0°C. 1st sample 1.96% error 2nd sample 0.81% error C. An unknown

Biology Laboratory Report Practical 4 Food tests Introduction The main components of food are proteins‚ fats‚ carbohydrates‚ and‚ of course‚ water. Proteins‚ lipids and carbohydrates are carriers about energy necessary for vital activity. They are a plastic material for the formation of structures of the body‚ as well as used for the synthesis of hormones and substances that transmit signals in the nervous system. Our food also includes food (plant) fibers‚ has recently seemed unnecessary ballast

On Friday July 15‚ my group of medical student visited the simulation laboratory. After climbing a couple sets of stairs we were broken off into three different groups for three different sets of activities. The first for me a combination of a couple of simulations. The first one was a simulation designed to help surgeons further develop their skills. We used small clamps to pick up and move rings to different poles. This seems quite simple but we had to do it looking at a monitor that projected
