A flame test is conducted when an element is burned and the flame produces a color different the starting flame color. When the coffee stirrer was put into the flame‚ the element’s atoms (from the solution of the stirrer) left the original level of energy. When the atoms fell back to ground level‚ they released photons in the form of colored flame. Using the flame test‚ unknown compounds can be identified when they are burned since each element has a specific color. (Douma‚ 2008). The color

Elizabeth – The Golden Age – Review The movie “Elizabeth – The Golden Age” (2007) is a remake‚ or better said‚ a sequel to the movie “Elizabeth” (1998). Both of the films feature Cate Blanchett in the role of Elizabeth I‚ Queen of England. The story begins in 1585 and is dominated by the intention of King Phillip the II nd of Catholic Spain‚ a very powerful empire at the time‚ to defeat and dominate England‚ ruled by a protestant Queen‚ Elizabeth. He is helped by Queen Mary of Scotland‚ who

11th D Flame Test Intro: The flame test is a procedure used by chemists to identify the presence of specified metal ions‚ based on the color the flame that appears along with it when it ’s heated. Our flame test was in lab class‚ where the main aim was to tested different solid metals in the flame in order to observe the wide variety of colors those chemicals also sometimes compounds (by mixing them) they produced‚ the second one was to identify unknown metals based on their flame color

Flame Test Lab Your company has been contracted by Julius and Annette Benetti. They are worried about some abandoned‚ rusted barrels of chemicals that their daughter found while playing in the vacant lot behind their home. The barrels have begun to leak a colored liquid that flows through their property before emptying into a local sewer. The Benettis want your company to identify the compound in the liquid. Earlier work indicates that it is a dissolved metal compound. Many metals‚ such as

Lab 20: Flame Tests Purpose/Objective: The ground state is the normal electron configuration of atoms or ions in an element. When atoms or ions in ground state are heated to a higher temperature‚ some electrons absorb enough energy to move them to higher energy levels. This is known as the excited state. However‚ the excited configuration is unstable‚ and the electrons must return back to their positions in the lower energy level. As they return‚ the energy that was previously absorbed is now emitted

Doing Business in Argentina Argentina has a stable political structure and the government is working on developing economy. I would choose to produce and sell solar panels in Argentina through Joint Venture with an Argentina company‚ which is one of the Investment Entry Mode. And I would send 1 in sales‚ 2 engineers‚ 1 accountant‚ 1 in shipping‚ 3 technicians‚ and 2 managers. Market reasons: Firstly‚ Argentina has enriched solar resource. “Argentina’s eastern plains and north western regions

Lab Questions: Are flame tests valuable for detecting metal ions present in a mixture of metal ions? Flame test may not be valuable for detecting individual metal ions present in a mixture of metal ions. Although each metal ion emits a different color of light‚ which corresponds to a certain wavelength of light‚ the presence of some elements may over power the flame and cause only certain wavelengths to be seen. For example‚ if sodium is present

Since this country is part of NAFTA/EU (respectively)‚ what are the pros and cons of us exporting to this regionally integrated market? I strongly recommend that our company shouldn’t be doing any exports to not only France but all the members within EU‚ or any similar regionally integrated markets. Since the main justification behind regional

this‚ rinse it with distilled water from the wash bottle‚ dip it into the Hydrochloric Acid‚ and place it in the burner flame for a few moments. 4. Take note of the color of the flame when the wire is clean. This is the color you should see after each cleaning. 5. Once the wire is clean‚ dip it into one of the solutions‚ place the wire in the flame‚ and observe the color of the flame. 6. Clean the Nichrome wire as directed in step 3‚ then repeat step 5 until all of the solutions have been tested.
