Introduction The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in
(8 points) Score 1. List the values for T-alkalinity for Sample A and Sample B. List the ppm value for sodium carbonate for Sample A and Sample B. Answer: I am unable to answer this question because I don’t think I have enough information. This is asking for exact values and I don’t have the data to answer it. I maybe overlooking the answer but I am unable to figure this out.
Final Lab Report James Dillon SCI 207: Dependence of Man on the Environment Instructor: Jessica Bostock February 20, 2016 Final Lab Report Abstract The experiments conducted for this lab report focused on water contamination and filtration. Experiment 1 was effects of groundwater contamination. Oil, vinegar, and laundry detergent were added to clean water with no means of filtration. The clean water was found to be contaminated. A filtration system consisting of cheesecloth and 60 ml of soil was created and the contaminated samples were filtered through it. The soil and cheese cloth did not affectively filter the contaminants. Experiment 2 focused on
The experimental procedures for Lab 2 were provided on Blackboard labelled as “Pre-Lab 2: Techniques & Measurement”.
PHYSICAL EXAMINATION Vision with correction 20/30 in the right, hand motion in the left. Applanation pressure are 11 in the right and 15-16 in the left. Anterior segments are clear and quiet. ____ visual field shows a dense superior hemifield in the right and generalized constriction in the left.
Methods Data were collected in September and November 2017 at the Elk Valley Preserve and Field Station in Banner Elk, NC. The preserve is located at 36°10'17.2"N 81°54'45.9"W, in Avery County in western North Carolina. The area is a mixed deciduous forest at an altitude of 1,127 m above sea level. Data were collected in early fall, during which temperatures average around 10-18 degrees Celsius. Summers in Banner Elk are typically mild, with temperatures averaging 21 degrees Celsius, and winters are cold and snowy, averaging near zero degrees Celsius. During the months of September and November there is an overall average precipitation of 12-25cm.
Eyes: Pupillary light reflex: Pupils are equal, round, reactive to light. Accommodation is present. Eyebrows, eyelids, and lashes are present, symmetric, and eyelids are a proximal completely. Conjunctive is pink, clear, with no swelling or lesions. Sclera is china white. Patient wears glasses and the glasses are in good repair. The last vision test was last spring and the patient gets an eye exam done every two years. The client states her left eye did not fully develop so she has always had bad vision in that one eye. However, when you look at the eye, you would never notice. Cataracts were removed in both eyes, but it was 3 years apart.
PHYSICAL EXAMINATION Vision without correction is 20/20 hand motion. Applanation 16 and 14. The anterior segment is clear and quiet in the right eye and there is evidence of iris neovascularization. He has a well placed PC IOL in the right eye. The left eye shows 2+ nuclear sclerosis with 2+ cortical spoking. Posterior segment of the left eye shows a dense vitreous hemorrhage with a positive red reflex. No evidence of retinal detail.

* Abstract The petroleum lab and environmental reflect the major focus of the lab well. The abstract concisely communicates the purpose of the lab, the approach, the results, and the significances of the findings. The electrical lab doesn’t have an abstract but sometimes instructors do not require an abstract section. The environmental lab does a better job at writing the abstract because it’s shorter and more direct to the point, therefore easier to understand.
The objective of this experiment was to calculate the mass of hydrogen collected and to compare it to the theoretical mass of hydrogen that should have been produced based on the limiting reagent off this reaction. First a 500 mL beaker was filled with little temperature water and then placed
I spent most of this week working on end-of-semester projects, reanalyzing my current set of data, and preparing for another round of kinetic experiments. Status of End-of-Semester Projects SURE Poster: The first draft is complete and was sent to Dr. Kissel before he left for vacation. This weekend we will make any
On examination, vision is 20/20 bilaterally. Intraocular pressure is 16 to the right and 18 to the left. Dilation has been provided on this visit with tropicamide 1%/phenylephrine 2.5%.

What is academic writing? A simple definition of academic writing is a form of writing that refers to writing done for several reasons. However, a broad definition is any writing done to fulfill the requirements of a college or university. Academic writing is also writing that is used for publications that are read by teacher and researchers or presented at conferences. A prime example of academic writing is lab reports. Lab reports are a form of writing that provides formal record of research or an experiment. These reports consist of objectives, procedures, and results that should be specific enough that interested readers could replicate the experiment. When doing research on lab reports I learned about how a lab report is its own
