up for Qualitative Analysis 1. Introduction- This experiment is for qualitative analysis so we are trying to find out what is in a substance. In this case we are using the flame test to try and discover what is in 4 unknown sample solutions that we have been given this is done by cross referencing the colour of the flame with 6 known solutions we test beforehand. Aim- In this experiment we are attempting to distinguish what substances are in the 4 unknown solutions by cross referencing with

was a dragon named Flame. It was a miracle fight. All of a sudden‚ Sparkle did his ice flame and Flame did his fire flame at the same time. It was a miracle‚ the whole dark-blue sky was glittery. Flame was even more in fight mode. Sparkle just looked up at the sky. He had a strange feeling. He felt that ice and fire had come together‚ but that was impossible. If fire touched ice‚ it would melt! Sparkle wanted to explain it to Flame‚ but it didn’t work. Some time later‚ Flame said‚ “Stop looking

using the developed quasi-dimensional cycle simulation (using two-zone burning model) program. The purpose of this paper is to model the geometric interaction between the propagating flame and the general cylindrical combustion chamber. Eight different cases were recognized. Appropriate equations to calculate the flame area (Af)‚ the burned and the unburned volume (Vb & Vu) and the heat transfer areas related to the burned and unburned regions were derived and presented for each case. Predicted results

each solution and any changes were recorded‚ and the solutions were disposed of. To begin the flame confirmation tests‚ 20 drops of each cation were added to its labeled centrifuge tube. A Bunsen burner was then connected to the gas jet and lit to where a sharp blue cone was visible in the flame. A Nichrome loop was then soaked in HCl and placed in the flame until there was no color change in the flame. This insured there was no further solution on the loop.

Chemical Gas Tests Procedure Part 1: Hydrogen and Manganese Dioxide 1. Inserted 4mL of hydrogen into a test tube 2. Scooped a little amount of manganese dioxide on the end of a wooden splint 3. Allowed the tip of the splint to flame using the Bunsen Burner 4. Allowed the reaction to proceed for a total of 15 seconds. 5. Placed the glowing splint into the test tube 6. Recorded the results Part 2: Magnesium strip and Hydrochloric acid 1. Poured 3mL of hydrochloric acid into a test

lights off‚ we placed the jug on the table and used a kitchen lighter to light it. In the dark‚ the flame was almost suspended in the bottle‚ burning the chemical inside. When we turned the lights back on‚ we saw that the only thing left in the bottle was water. The jug was warm to the touch and the air smelled like gasoline. I conclude that this experiment had a chemical reaction because the flame mixed with the ethanol to make a new substance‚ which was water. For the next experiment we worked

colour of the flame when burning with different alcohols. - Methanol was a blue coloured flame which was slightly orange at the top of the flame. This is because there is a high amount of complete combustion and the carbon atoms are not becoming a waste product. - Ethanol burnt with a blue flame that was a more intense bright orange colour towards the top of the flame and more orange flame than methanol. - Propanol burnt a small amount of blue at the base of the flame but the majority

element‚ and put it over the bunsen burner to observe the flame emitted. While observing the different flames‚ we saw that different elements did indeed emit unique flame colors. Colors such as red‚ violet‚ and turquoise were emitted. All of these represented the different energy emitted when the electron changes energy levels. We concluded that potassium had the highest energy emitted. Some sources of error include the q-tip affecting the flame emitted. Also‚ when calculating the unknown

rich and vital imagery. ‘Flame- Tree in a Quarry’ (henceforth ‘Flame-Tree’) and ‘Train Journey’ are just two of Wright’s many poems that she has written that include these qualities. In these poems‚ Wright expresses her passion for the country she loves so much and her frustration and sympathy for her country as it is constantly being destroyed. ‘Flame-Tree’ and ‘Train Journey’ share many similar techniques. “From the broken bone of the hill”‚ this opening line from ‘Flame-Tree’ is a great example
