Laboratory Report on the Reaction of Flames Towards Medals  Introduction The purpose of the flame lab was to identify a set of flame-test color standards for selected metal ions‚ relate the colors of a flame test to the behavior of excited electrons in a metal ion‚ observe spectral lines using diffraction grating‚ and to identify an unknown metal ion by using a flame test. My hypothesis for the lab was that most of the flames when sprayed with a solution will be a orange-red color. The

ACTIVITY 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

Switches are connected using different methods such as three-way and four-way switches‚ grounded conductors and switches controlling light loads. The three-way and four-way connection method is simply used to create lights that operate using more than one switches; mostly done to change

Word: Fire and Flames(part 1) “5:22- But I say unto you‚ That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother‚ Raca‚ shall be in danger of the council: but whosoever shall say‚ Thou fool‚ shall be in danger of hell fire.” There is a known relation between sin and fire. Throughout the New Testament‚ there have been instances where the “hells of fire” have been mentioned. It has been said that fire is an expression of

Livana Partners : Rachel Gideon‚ Joy 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

Place the end of one of the popsicle sticks soaked in a solution into the flame. Note color(s) of the flame and the duration of each color. Immerse the wooden splint in the distilled water to fully extinguish it‚ and then discard it in the trash. Record your results. 2. Repeat step 4 for each of the remaining salts. 3. Repeat step

Flame Test Lab Morgan Chemistry CP 5/30/14 Abstract- In the flame test lab‚ the flame test was performed to excite the electrons in the samples and observe the color of the flame. The flame emits a color because each element has an exactly defined emission spectrum‚ which one can use to identify them. For example‚ NaCl was highlighter yellow‚ Sr(NO3)2 was sun orange‚ CuCl2 was turquoise‚ LiCl was neon red‚ KCl was solar flare yellow‚ and BaCl2 was Voldemort green. Introduction- In Bohr’s
