Identify The Three-Component Mixture

Materials assignment notes. We have come together as three separate companies who have experience of working with each other on many other projects, to provide the specified requirements that the client is looking for. After surveying the site and looking at the surrounding areas we have come up with a design that incorporates all three of our products.

To separate the Ramos mixture the group first first conducted the dissolve, filter, evaporate method, and prepared the lab for as well. Though for this lab the substance

Double Replacement Lab Report Date Completed: October 8, 2015 Objective To analyze and determine if a chemical reaction occurred between two compounds using the concepts we learned in class. Also, if the chemical reaction occurred, to determine if it formed a precipitate or gas. Safety General Safety Precautions: Do not touch the chemicals Use of gloves and coats are recommended, use of goggles should be required Keep the work area clean Dispose of the chemicals properly, DO NOT dispose them in the sink Clean up your work station Wash your hand before and after the lab Make sure all chemicals are labeled correctly NEVER return chemicals to reagent bottles Use the wafting technique to smell the chemical Clean up spills immediately

Title: Introduction: A-mountain lies in Southern Arizona, a region known as a desert. There are factors that contribute to the growth of certain plant life in certain areas. The north and south side of the mountain is expected to have contrasting difference due to the amount of sunlight each side receives. Exposure to sunlight affects the plants growth and overall life.

For this lab the objective is to see how the properties of individual substances compare with properties of mixed substances. For this lab the research questions is mixture, homogenous mixture, and heterogeneous mixture. A mixture is a combination of 2 or more substances that are mixed together physically but not combined chemically. Also a homogeneous mixture is a uniform in structure or composition throughout the substance. Lastly, a heterogeneous mixture is a consisting of dissimilar parts of elements (not the same).

You can create an inventory policy for the office by scheduling inventory to be taken monthly, or weekly, whichever schedule fits your offices ordering needs. You could distribute the task among employees by doing it in pairs or assign a list of supplies that each person is responsible for keeping inventory of. A very vital tool for completing an inventory check is having a list of the supplies and equipment that you need to take inventory of. You can use Excel to create the inventory list. I would recommend that this list have at least two columns.

In this lab, three unknown compounds were separated from a mixture and identified by melting point. Unknown mixture #124 has components of acid, base and neutral compound. The compounds were identified by melting point and matched up with the known melting points from a given list. In order to identify the compound it was important to separate by dissolving the mixture in an organic solvent which was not soluble in water, and then extracting the solution first with HCl, and then dilute sodium hydroxide solution. From the separation mixture, the aqueous layer were obtained and labeled as TT-1 (base), TT-2(acid) and TT-3 (neutral) in three different test tubes for later recovery.

Hence in the sample only copper (II) chloride will dissolve leaving the sodium chloride behind once filtered through. The copper (II) chloride can then be obtained by evaporating the methanol; which has a boiling point of 65 degrees celsius whilst copper (II) chloride has a boiling point of 993 degrees celsius, thus allowing the methanol to be easily evaporated out of the solution eliminating concerns of the copper (II) chloride evaporating alongside the methanol. Purpose To investigate different methods of separating copper (II) chloride and sodium chloride in order to obtain the original masses of both substances.

Use the evidence provided by the tests to identify the mystery powder. The mystery powder (#5) is the baking powder. My partners and I figured this out because the physical and chemical properties of both of the substances are very similar. For example, both powders are not soluble in water, and they both turned red when they reacted with the universal indicator.

How do the goals of a liberal arts education lend themselves to achieving academic integrity? Liberal arts education provides opportunities for students to become widely informed and skilled citizens. It allows students to have awareness in different areas of studies and develop broader cognitive abilities. Moreover, liberal arts education states several values which are to be developed in students throughout their studies. Academic integrity is the set of values for behavior which encourage to avoid plagiarism, cheating, and dishonesty in academic life.

Abstract: The purpose of this experiment was to identify given Unknown White Compound by conducting various test and learning how to use lab techniques. Tests that are used during this experiment were a flame test, ion test, pH test, and conductivity test. The results drawn from these tests confirmed the identity of the Unknown White Compound to be sodium acetate (NaC2H3O2) because there were no presence of ions and sodium has a strong persistent orange color. The compound then will be synthesized with the compounds Na2CO3 and HC2H3O2 to find percent yield.

Exercise 14: Unknown Identification Lab Report The purpose of the study was to identify the unknown bacterium using various biochemical tests in addition to using scientific methods in determining the outcome of the hypothesis. Each biochemical test will help determine the bacteria based on specific characteristics of each organism. I was giving unknown number 232. The first procedure that needed to be done after obtaining unknown bacterial mixture was to isolate the two bacteria in a pure culture using the streak plate method described in Microbiology Laboratory Manual Eight Edition. The material used was trypticase soy agar (TSA) plate, nutrient plate, starch agar, hydrogen peroxide, iodine reagent and microscope.

Experimental Procedure Identifying the Unknown We performed three tests on our compound to definitively identify it. First we combined 5 g of our unknown compound with 10 mL of distilled water and measured the pH change in the water to test its solubility. Then, to try to identify the cation present in our compound and narrow down the possibilities, we held a sample over a flame and watched for color change. We performed an acid test where we applied a few drops of HCl and watched for a bubbling reaction, to test for the presence of carbonate.

TLC was used to identify the actual unknown product as well as other products/reactants present in the filtered solution. The procedure was conducted by placing a TLC plate in a developing chamber that is filled with a small amount of solvent. The solvent cannot be too polar because it will cause spotted compounds on the TLC plate to rise up too fast, while a very non-polar solvent will not allow the spots to move. The polarity of the spots also determines how far it moves on the plate; non-polar spots are higher than polar ones. After spots on the TLC form, the Rf values are calculated and used to analyze the similarity of the compounds.

How Transmission Fluid Warns Of Potential Problems With Your Car's Transmission Monitoring the transmission fluid in your car is one way to track the condition of the transmission. You should get in the habit of checking the fluid periodically just to make sure everything is working okay. You'll want to check the fluid level along with the color and consistency of the fluid. Here's what you need to know.
