found in a compound. And in order to detect the presence of metals in a compound‚ flame test is done. The result of the flame test is based on each element’s characteristic which is emission spectrum. Flame test involves placing a sample of an element or compound in a non-luminous flame and observing the resulting color of the flame. Flame test is fast and easy to perform. All the equipment needed for flame test is present in all chemistry laboratories. Solubility is a quantitative term defined

The Urea test was used to test both Unknown Gram-positive and Unknown Gram-negative bacteria. One colony of bacteria was used from the Unknown 13A plate and Unknown 13B plate in order to inoculate the Urea Slant. After the slant was inoculated‚ the cultures were placed in an incubator at 35ºC for Gram-positive bacteria‚ and 37ºC for Gram-negative bacteria for a total of 48 hours. If the Urea test were positive‚ the color of the slant would have changed to a hot pink color‚ which indicated the bacteria’s

FLAME TEST Summary The purpose of this lab was to see how different compounds can change color while in a flame and with this color‚ I can identify the compound. The test involve putting sample element and see what color appears. Also Thermal excited electron goes from low to high energy level which raises the color but when the excitation ends electron gets to lower level which makes the color back to normal. In order to determine the identity of several unknowns‚ I will perform flame tests and

Tata Iron and Steel Company was established by Dorabji Tata on August 25‚ 1907‚ as part of his father Jamsetji’sTata Group.[11][12][13] By 1939 it operated the largest steel plant in the British Empire. The company launched a major modernization and expansion program in 1951. Later‚ the program was upgraded to 2 MTPA project. In 1990‚ it started expansion plan and established its subsidiary Tata Inc. in New York. The company changed its name from TISCO to Tata Steel in 2005.[14] In August 2004‚

First‚ the plate was analyzed for its hemolysis characteristics. Afterwards‚ a Gram stain was performed from a sample of the agar plate and the slide was viewed under the microscope. Once‚ the microscopic visual was captured‚ a catalase test followed. Next‚ for further data‚ MSA results were recorded‚ along with antibiotic observations of

Boake‚ Hannah Harper Various Color of Light as the Effect of Electron Emission Objective Observe the characteristic colors produced by certain metallic ions when vaporized in a flame. Identify the unknown metallic ions by means of its flame tests. Background When atoms absorb energy‚ electrons move into higher energy levels‚ and these electrons lose energy by emitting light when they return to lower energy levels. Energy levels are fixed energies that electrons can have. Ordinary light

Students‚ at the end of the training programme‚ do present reports on their practical experiences at a departmental interactive forum where faculty members jointly access individual student’s performance on the programme as is required by the SIWES curriculum. Currently‚ six hundred students drawn from seven colleges

This section will explore the concept of the iron triangle and related terms such as pork barrel politics. This thesis will look into the debates surrounding the concept of the iron triangle in the next chapter. In this section it will be explored what the nature of the iron triangle is‚ how it came into being and what kind of effect it had on Japanese society. The iron triangle First‚ we need to establish what the concept of the iron triangle entails. Japan rebuilt its economy after the Second

Food Test 1: Test for Glucose – with Benedicts solution Benedicts solution is used to test for simple sugars‚ such as glucose. It is a clear blue solution of sodium and copper salts. In presence of simple sugars‚ the blue solution changes color to either green‚ yellow or brick-red‚ depending on the amount of sugar. Method 1) Mix smalls amount of each food sample (i.e.‚ Egg lumen‚ cylindrical piece of potato tuber‚ bread crump and crisps) in different test tubes with distilled water to make a

element tensile test is conducted for element size of 5mm at strain rates mentioned in Fig. 7 7. The true stress versus plastic strain results of the simulation in comparison to the load curve is shown in Fig. 7 9. As the damage is coupled to the stress tensor by Eq. 4 1‚ there is a continuous reduction of stress. The plastic strain at failure for different strain rates is shown in Fig. 7 11 which is in accordance to the scaling factor given for different strain rates. One element tensile test is also conducted
