Associate Level Material Mineral Identification Worksheet Open the simulation and print this worksheet and the Mineral Identification Job Aid. Then do the following: 1. Conduct all tests on the minerals in the virtual lab. Minerals in the virtual lab are numbered 1–7. Keep track of which mineral you are working with as you record your observations.
| Iron filings | Black, small, magnetic. | Salt | White, dissolves, edible. | Sand | Brown, minerals, grainy texture. | 2. Materials: In order for us to do this lab we need a few things.
Find the molarity is essential to numerous amounts of future procedures such as equivalent weigh. The titration of hydrochloric acid was also completed for practice of titrating and basic understanding of the characteristics of the strong acid. In all three titration experiments an indicator was used to illustrate the
Since we used our chromatography method, we will be able to figure out which metals our substance contains. It is important to know this especially if we are ingesting and coming in contact with them. Chromatography is a separation technique that works based on the compound interactions as those compounds tend to move within a supporting medium. The compounds interact in two phases; mobile and stationary phase. The techniques help analyzing.
Calculate how much zinc left the penny. Post this number on the board. Calculations: (do rough drafts of calculations in your lab notebook. Your formal report should have very well organized, well labeled, calculations.) 1.
Liquids & Solids Pre Lab Questions: 3pts 1. What are the learning goals of this lab? The goal is to view and experience the melting point and boiling point of different substances. 2. Why is acetamide not allowed in contact with your skin?

Chem 1 Lab B. Reflect on the important scientific practices of (1) Asking Questions, (2) Planning and Carrying Out Investigations, and (3) Analyzing and Interpreting Data by doing the following: 1. Define each of the three scientific practices. a. Asking Questions: Asking questions is where we discuss what we are looking for in our scientific practices, asking what, when, where, why, how and who.
End of Lesson Questions Instruction: ANSWER ALL QUESTIONS CORRECTLY 1. Determine three other Alloys apart from those in your notes and give examples of their uses 2. Explain with diagrams why alloys are harder and stronger than pure metals 3. The table below gives the density, M.P. and electrical conductivity of some metals Based on the data provided in the table below and your knowledge of the reactivity series, answer the following questions: a.
It is necessary to estimate the natural frequency of the PCB. For this estimate, one has to have an accurate estimate of E value of the PCB. PCBs are designed and manufactured with a variety of polyamide materials such as solder mask, metallic material such as copper trace, composite materials such as pre-preg and core material. For military application the PCBs are made up of different layers of copper which plays important role in the thermo-mechanical behaviour of the substrate due to the large Young?s modulus of copper at both room temperature and reflow temperature. In this paper the estimation of E of PCB and using that estimation of natural frequency of PCB was carried out both analytically and experimentally to provide safe mounting design of the PCB in the military electronic
