Heat Treatment and Qualitative Metallographic Analysis Lab ME 3228: Mechanics & Materials Laboratory Summary Comparing a material's initial treatment and the microstructures that are formed from different processes, an engineer can accurately understand why certain treated materials of the same family can be stronger than another. In this experiment annealed and cold-worked specimens of AISI 1018 STEEL are used, along with a Hardness tester, a grinding and polishing process, and a micrograph
OBJECTIVE The main objective of this experiment is to carry out qualitative analysis to identify metal cations in unknown solution 1. INTRODUCTION An unknown material can be determined by using simple chemical tests and separations which is called as inorganic qualitative analysis. The separation of cations depends on the difference in their propensity to form precipitates. Separation scheme is used to classify cation into five groups on the basis of their physical and chemical behavior opposed
September 23rd, 2014 Matter & Qualitative Lab Report Purpose:- The purpose of the lab is to perform series of tests to determine the physical and chemical characteristics of several unknown powders, and then use that information to classify the unknown powders. Hypothesis:- I believe that by testing substances with various chemicals, for example, vinegar, iodine and that will help to find out what the substance is and what is it quality. Materials:- In order to perform this lab, you need:- • Litmus
Identifying inorganic compounds using qualitative analyses and chemical tests Jessica Vithayathil U84363206 CHM 2045L Section: 033 Aaron Clark October 13, 2016 Introduction Due to climate change during the turn of the 21st century and overall population growth, scientists have noticed greater amounts of negative impact on water sources (Barber, 2011). Waste Water Treatment Plants (WWTPs) have been identified as one of the root causes of stress for these water sources (Barber).
Introductory Chemistry 1110 Qualitative Analysis Using Precipitation Reactions Lab reports are due week of September 29 – October 3, 2014. Your lab report must contain the following information: Experimental data may be collected with other students in introductory chemistry labs. However, I understand that sharing information required for a lab report or unknown submission (including but not limited to word processing or spreadsheet files, calculations, graphs, conclusions and additional
distinction is often made in sociology between quantitative and qualitative research methods. Quantitative methods intend to measure social phenomena by using mathematical methods and statistical analysis. On the other hand, qualitative methods mean to collect rich, detailed data, allowing for an in-depth understanding of an individual. “It is often assumed that quantitative approaches draw on positivist ontologies whereas qualitative approaches are more associated with interpretive and critical paradigms
to making bread to leaves changing colour in the fall. A chemical reaction is the process that occurs when two or more substances combine to produce a chemical change. When a chemical reaction takes place, the change is indicated by one or more qualitative properties. The colour or odor could change, gas could be produced, a precipitate – a solid substance in a solution - could be formed, or energy could be absorbed or released. The substances initially involved in a chemical reaction are called reactants
Writing Intensive courses in the majors and beyond. In relation to the course learning outcomes, the works I have done have been majorly about Discourse, discourse communities, genres, writing expertise, research questions, and collection and analysis of qualitative data. Over the semester, I was tasked with completing several pieces of writing that would demonstrate my progress in understanding of the above mentioned topics. In order to achieve this understanding, I was to review literature from respected
sections of data: one section of qualitative data (choose either Gender or Position) one section of quantitative data (choose either Intrinsic or Extrinsic) Each section should include all data points listed in the column for the variable. The requirements include: Identify the data you selected. Explain why the data was selected. Explain what was learned by examining these sets of data. Your analysis should include using Microsoft Excel to
Record the raw quantitative data in the table below: Electrical Potential Difference Between Zinc and Copper Solutions Electrical Potential Difference Variation in Copper Chloride Trial 1 Trial 2 Trial 3 0.5 1 1.5 2 2.5 Record qualitative data as well in the Observations section. When all quantitative data has been collected and recorded, use the equation below to calculate the average electrical potential difference, or Average E_Cell of each variation of Copper Chloride. Ave
