Lab 9 Working with Printers Exercise 9.1 Installing a Printer Overview Contoso‚ Ltd. has just taken delivery of several new printers that the IT director purchased through an auction. He has assigned you the task of installing the printers and making them available to the users of the company network. For the first printer‚ you intend to connect the unit directly to an LPT port in the Windows 7 computer that will function as the print server. In Exercise 9.1‚ you install the driver for the printer

of Oxalate Ion in Ferric Oxalate Trihydrate using Titrimetry Abstract: In this two-part lab‚ we will learn about coordination compounds and their uses with stoiciometry. We will also find out about how theoretical yield is calculated from a reaction we will create. We will also synthesize Potassium Ferric Oxalate Trihydrate (K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O) using a two step reaction. In the second part of this lab we will calculate how much Oxalate Ion is present in the K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O using

Lab Report Problem: What method would consistently test the foam and ensure it has the correct density? Background: There are words that need to be understood before executing the experiment. The first thing you need to know is density. Density is a measure of mass per unit of volume. The reason for testing density of doors because doors must contain a density of 14.34lbs per ft3 of foam‚ or it will collapse if the density is too high. If the density is too low‚ it won’t allow for normal expansion

Flame Test Laboratory Report Introduction The purpose of this lab is to observe and identify metallic ions‚ using flame tests. The traditional flame test originated when Robert Bunsen invented the Bunsen burner to test two new alkali metals he and his partner had discovered. “A flame test is an analytic procedure used in chemistry to detect the presence of certain elements‚ primarily metal ions‚ based on each element’s characteristic emission spectrum” (Flame Test 1). Using this test‚ an element

LAB 4 Read over the parts of the microscope and answer the following questions: 1. What do you call the lens you look through on the microscope? Ocular 2. What is the difference between the ocular lens and the objective lens? Ocular lens is the lens you look through and objective lens is the lens that is close to the stage. 3. Where do you place the slide on the microscope? the stage under the stage clips 4. Which adjustment‚ course or fine‚ do you use when you are observing the

Modeling Effective Dose: Salt Tasting lab Purpose The purpose of this lab is to see at what measurements (of salt) can the salt be detected by taste. Abstract The science of toxicology is based on the principle that there is a relationship between a toxic reaction (the response) and the amount of poison received (the dose). An important assumption in this relationship is that there is almost always a dose below which no response occurs or can be measured. A second assumption is that once a maximum

n this lab experiment factors that affected solubility are temperature‚ liquids‚ concentration‚ pressure‚ polarity‚ and molecule. In this experiment we use temperature‚ centrifuge‚ and concentration solutions to be able to achieve the results that we wanted. Step one of the experiment was to mix HCl‚ to cause a precipitation form‚ after that we had to decant the solution‚ then we used a centrifuged to separate the the precipitate of the supernatant liquid. After the decant was done‚ then the process

Based on the knowledge I gained from the blubber lab‚ I discovered how homeostasis is maintained by feedback loops in regards to blubber. A negative feedback loop is a process where change is prevented and a certain set point is kept. In this experiment‚ the negative feedback loop was the blubber preventing the changing temperature of the thermometer. Therefore‚ blubber is a method of homeostasis‚ because it prevents the ideal temperature of the thermometer from dropping. Our data shows this as well

Background: Techniques used were in accordance with NMU Professor Dr. D. Becker’s lab manual (ISBN 0-390-53911- 2; McGraw Hill). Changes in protocol or interpretation are noted where they were implemented‚ but strict adherence to the manual prevailed. Materials and Methods: Microscope‚ incubator‚ and deionizer functioned correctly throughout testing period‚ with stains‚ dishes‚ agars‚ and test reagents readily available. Lab procedures are considered orthodox and usage thereof is noted chronologically
