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

provided by the inexperienced staff assistant the most obvious analytical procedure to start with is to compare the 2005 financial date with the 2004 financial data. By analyzing the two years against each other‚ I have noticed that it appears Laramie Wire may be building up their inventory stores. I state this because their finished goods inventory has went up from $1‚175‚500 to $1‚654‚500 in just that one year. This is an increase of finished goods inventory of 40%. This is something which I believe

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

Flame test: AIM: To determine which part of the salt is responsible for the characteristics in the flame. HYPOTHESIS: If we introduce a metal salt in the blue flame of the Bunsen burner‚ then the colour given off by the flame is due to the metal part of the salt. METHOD: (1) With a heat proof mat under the Bunsen burner‚ turn the gas on and light up the Bunsen burner with matches. (2) Pour enough Hydrochloric acid into a beaker. (3) Using your wire‚ dip it into the beaker containing Hydrochloric

Calcium Carbonate due to results from the Flame Test and Anion I Test. Throughout our lab days‚ my friends would help me determine various odors and colors of the substances which allowed me to confirm my answer. Also‚ I looked select test results up on the internet to see if they matched my observations. On our first lab day‚ I received my bottle and noticed a white precipitate in the bottom therefore‚ my unknown was insoluble. I started my testing with the Flame Test and did not evaporate my unknown

Laboratory Report: Flame Colors of Metals Abstract The experiment about flame color of metals demonstrates how electrons jump into their excitedstate from their ground state as it came in contact with heat. As it return to its lower energy state‚it emits the absorbed energy in the form of light. A platinum or nichrome wire was dipped into aconcentrated HCL and was heated to clean it. The wire was dipped into different salt solutionsand heated in order to determine the metallic ion’s color and wavelength
