Identify an unknown carbonyl compound © KCl http://hk.geocities.com/fatherofchemistry Objective To classify a carbonyl compound by a simple test and to identify it by the precipitation of a derivative. Principle In this experiment‚ the unknown compound is either an aldehyde or a ketone from Table 90. In the first part‚ on undergoing Tollen’s & Fehling’s tests‚ ketone will have no reaction. In the second part‚ by preparing a derivative of the compound with 2‚4-dinitrophenylhydrazine

1)Calculate the amount of your compound interest investment after 10 years. Remember that you are starting with $7‚500. $10‚642.83 work: A=7500(1+3.5%/365)^365x10 = 7500(1+0.00009589)^365x10 = 7500(1.00009589)^3650 = 7500(1.419041609) = 10‚642.83 2)Calculate the amount of your simple interest investment after 10 years. Remember to use the same rate and compounding as in #1. $2‚625 work: 7500x.035x10 = 7500x.35=2625 3)Create a graph that shows the growth of your compound interest and simple interest

and amounts of each compound in your mixture. 2. Draw a flow chart (like pg 687 in PLKE) showing how you separated and isolated your two compounds. Be sure to include the structures of the compounds at each step. 3. Write a procedure. This should include exactly how you performed your separation. It should have enough detail so that someone else in the lab could repeat the experiment. 4. Results and Conclusions. a. Melting point‚ weight‚ and % recovery for each compound. b. Comment on the

Flame Test Lab Question: When a compound is placed in the flame of a burner‚ what happens to the color of the flame? Hypothesis: When the compound is placed in the flame‚ the flame changes color depending on the chemical compound. When they’re heated‚ they gain energy and changed color sometimes. Safety Requirements for this Lab: Wear goggles at all times. If you want to remove them to write in your notebook you may sit at a table in the center of the room. When you sit down remove them

Gas Chromatogram (GC) and mass spectrum was used for further analysis‚ in order to find out what exactly was this drug‚ and find its mixtures and compounds. Results From the chromatogram/spectrum peak report it is shown that there are two retention times of 15.67 and 9.66. The first peak has 9.66 retention time and has one possible match out of the five which is included in appendix 1.The highest

that substance is revealed through a seires of tests that involve chemical and physical properties of that substance. Problem: You are given an unknown chemical substance that you need to be able to identify. How are you going to do this? The compound can be either harmful or toxic‚ so what you need to do is test all of its physical and chemical properties‚ and then find out the synthesis of the substance. Qualitative testing and quantitative testing is essential in discovering what the unknown

Well look at the periodic table of elements if its on there then it’s an element. How do you know if its a compound? Well a compound is made up of two or more elements. So look at the name for example NH3 then it is a compound because it has a nitrogen molecule and 3 hydrogen molecules. Science changes everyday and without our current

It is the chemistry of the compounds of carbon along with other elements such hydrogen as are found in living things and elsewhere. The organic compounds available to us today are those present in living things and those formed over millions of years from dead things. In earlier times‚ the organic compounds known from nature were those in the ‘essential oils’ that could be
