...Lab #1 “Who has the same solid that I have?” Abstract Different Physical and chemical tests were performed on 10 numbered unknown solids and the results of all tests were compared as a class to try and determine which groups had the same unknown solids based on similarities in properties. It was found that my given unknown solid #11 shared similar properties with the unknown solid #1. A side by side analysis of the reactivity test in which Hydrochloric acid (HCI), lead nitrate (Pb(NO3)2) and sodium hydroxide (NaOH) was added to three separate samples of the compounds unknown #1 and #11 aqueous solutions. The results for both unknowns were identical, leading to the conclusion that my unknown solid #11 was the same unknown solid as #1. Introduction When conducting research it is important to be comfortable communicating your results with other researchers so that they can be further analyzed and compared with the results of other research experiments. Another large part of conducting research is to be comfortable determining, describing and comparing chemical and physical properties of compounds. Many compounds can look very similar, but have drastically different chemical properties, so it is important to know which tests can be performed on a compound to help determine what it is, or what it is not. In this experiment 2 sets of six unknown solid compounds were put into small jars and labeled with the numbers 1-12, numbers 4, 6 and 8 were not used. Each lab group was given...

...to find out the pH range of the indicator you use. Color pH indicators only provide an approximate measure of the pH, or the strength of the acid or base(swc2.hccs.edu). They are not as accurate as the instruments the scientists use to measure pH, but they acceptable for the experiments below. What is the pH of various solutions? There were two experiments conducted: The Pre-Lab Exercise and Procedure B. Pre-Lab Exercise In this experiment, two different approaches were used to measure the pH for a variety of substances. One was the pH paper and the other was the electronic pH meter. | pH measured with pH paper | pH measured with pH meter | calculate the following values using the pH values obtained with pH meter | Solution | | | pOH | [H3O+] | [OH−] | soap solution | 8 | 7 | 7.00 | 1.00E-07 | 1.00E-07 | Coffee | 4 | 4.69 | 9.31 | 2.04E-05 | 4.90E-10 | lemon juice | 2 | 2.35 | 11.65 | 4.47E-03 | 2.24E-12 | Vinegar | 2 | 2.31 | 11.69 | 4.90E-03 | 2.04E-12 | sea water | 7 | 5.57 | 8.43 | 2.69E-06 | 3.72E-09 | aquarium water | 7 | 6.53 | 7.47 | 2.95E-07 | 3.39E-08 | Figure. 1.

...easy machining tough. The question seeking for an answer of the investigation is “Can buying brass ingot and roll it flat to get a 60 percent reduction in thickness and hardness of 45 without it cracking?” For this experiment, there was two test that was conducted, Cold Working test and the Heat Treatment Test, on a sample of 260 Brass in ingot form. For the Cold Working Test, the first done was putting the sample through a Stanat Rolling Mill to reduce the thickness of the ingot. Part two of the Cold Working Test was to use the Rockwell Hardness Tester to measure the hardness of Brass. Do this test ten times at increments of -0.75 from 10.5mm to 3mm. At each targeted thickness, measure the width and length. The result of the test is on Table 1. After doing the Cold working Test, Heat treatment test is done. For this test, take the 3mm brass plate and cut it into 5 equal pieces and place each piece into the5 furnaces at 100°C, 260°C, 350°C, 450°C, and 565°C.

...lacking either one of them, our body would receive the consequences. Carbohydrates are one of the most essential sources of energy for our body. They a composed of the three elements, carbon (C), hydrogen (H) oxygen (O), and in the ratio of 1:2:1. With the general formula Cn(H2O)n. There are three common groups under carbohydrates, which are monosaccharide (simple sugar), oligosaccharides and polysaccharides. All of these groups possess different carbon structural and function between one another. There are many types of experiments that can be conducted to identify and differentiate the group from each other. Thus, the alb activity can surely help to further understanding between the relationship of the groups’ structure and their function.

...Abstract Species diversity in Guam’s limestone forests is extremely limited. In order to account the number of species available in comparison to the Panama tropical rainforests, data gathered from of 20x20 plots were recorded. Throughout this study, factors for Guam’s limited species diversity may be generalized but not fully confirmed. Overall the main purpose is to get an idea of what type of species are available in the limestone forests, as well as provide data for researchers to pursue further studies as to why species are so limited here on this island. Introduction Tropical rainforests, along with temperate ones, are the most complex biomes on earth. This is due to the many ecosystems found within them. Although it is assumed that rainforest are fertile with plant species due to nutrient-rich soil, it is not. Most nutrients are either washed away from the soil due to heavy rainfall or recycled through the vegetation. Usually new growth within the forest greatly depends on decomposing organisms, such as bacteria and fungi (Tang et al.2011). Specie diversity varies within these rainforests depending on conditions surrounding and affecting each. Considering that species diversity is one of many crucial elements to nature conservation, thorough studies must be conducted to identify such conditions of limited rainforests. (Primack 1993). Categorized within Tropical forests are karst or limestone forests that consist of endemic plants and trees. Guam’s limestone...

...University of West Florida Department of Physics PHY 2053L University Physics I Lab Section: 81419 Lab Report Number: 1 Lab Title: Meaning of Measurement Name: Group Members: Date: 8/27/2014 PURPOSE: Learn the basics of measurement and statistical analysis in context of volume and density. EQUIPMENT: Three different geometric solids: 1 identified as white cylinder, 1 identified as brass-colored cylinder, 1 identified as silver-colored sphere. Meter stick (wooden, displaying measurements in cm) Analog scale (zero-ed prior to experiment) Manual caliper Digital caliper (zero-ed prior to each measurement) PRINCIPLE: This lab is intended to reinforce the importance of using proper techniques to attain precise measurements. It further demonstrates that reliability of results from different measuring devices. In this experiment, the most rudimentary measuring tool was the meter stick followed by the manual caliper and then the digital caliper. Measuring each object five times should reinforce the different interpretations of team members as well as the variance between the different tools used to measure the objects. In addition to measuring the length, width and height of each object, the mass was attained through the use of an analog scale. While a digital scale would have shown a more precise measurement, the analog scale was a more appropriate tool with the meter stick and manual caliper as the significant figures produced by each ...

...Lab #1 – Report file Identifying Threats and Vulnerabilities in an IT Infrastructure Course Name and Number: Risk Management IS355 Student Name: Sherry Best Instructor Name: Nicole Goodyear Lab Due Date: 1/16/2018 In your Lab Report file, describe how risk can impact each of the seven domains of a typical IT infrastructure: User, Workstation, Local Area Network (LAN), Local Area Network to Wide Area Network (LAN-to-WAN), Wide Area Network (WAN), Remote Access, and System/Application domains. Risk is the likelihood that a loss will occur. A loss results in a compromise to business functions or assets. • User Domain can come in various forms; people are the weak link here such as a user writing a password on a sticky note and sticking under the keyboard or on the monitor. Unknown to the user a malicious individual can log unto the network or domain using that person's credential to steal or launch a DoS or a DDoS attack. This can overwhelm the entire network that can lead to loss of revenue for the organization....

...1) As an individual, what did you contribute/accomplish in lab this week? 2) What did you learn (individually and as a team)? 3) How can you or your team improve in the future? 4) As a team, what do you need to accomplish in lab next week? 1) In lab this week, after multiple attempts to evaluate and redesign the cranking system for the dollar bill side of our project, we (my lab partner and I) decided to use six dowels to fabricate the conveyor belt. We went over many designs, mostly facing the same problem: no supporting unit for the system. We eventually came up with a design that attained our need and started fabricating in lab. However, since we should have figured this out earlier, we had to work on fabricating out of labs so that we could catch up with the progress. 2)...

...Figure 10 shows both frequencies superimposed together. It is observed that when one frequency is low, the other remains high. In other words, only one tone is generated at any point in time. With these simulations, it can be inferred that the Ltspice results were as expected. Since these results align to what is known in theory, it is considered to be accurate. The prototype is only then built and tested with an oscilloscope. The results is recorded and shown in the figures below. 4.2 Oscilloscope Readings Figure 11: Oscilloscope Waveform for A1 Figure 11 shows the square wave produced from A1. The frequency obtained was 1.14Hz. Figure 12: Oscilloscope Waveform for A2 Figure 12 above shows A2 producing a frequency of 440.51Hz. Figure 13: Oscilloscope Waveform for A3 Figure 11 shows A3 producing a frequency of 1.4439kHz. Figure 14: Oscilloscope Waveform for both frequencies The results obtained from the oscilloscope measurements were relatively accurate. This can be seen by the two distinct waveforms occurring at separate times. Since these measurements tally with the Ltspice simulations, it clearly shows that the prototype is fully functional. The slight difference in the frequency values could have been attributed from several factors. Simulations produce frequency values under perfect conditions. On the other hand, the practical approach is faced with imperfections such as noise, internal resistance from components and experimental inaccuracies...
