In this lab, we tested different experiments on a candle flame in order to better understand properties, combustion, and states of matter. We recorded many observations that could help us reach a conclusion using what we saw happen. When we observed the regular candle flame, we concluded that the heat of the flame vaporizes the liquid wax. Then, we blew this candle out and took a different lit candle into the smoke trail from the burnt out candle. The wax vapor in the smoke is combustible, therefore when introduced to flame, the vapor is burned and it relights the first candle in a fast process. We placed a wire gauze that is fire retardant very close to the candle flame. This seemed to shorten the flame and the smoke went through the holes…
This is a test to see if SO4 is present in the solution. If the
mixture has a white precipitate of Barium Sulfate, then the solution has a sulphate ion present (4).
Taking one of the remaining test tubes, add 0.1 mL of BaCl2 into the solution and mix well.
Fig 5. If HCl is present in the solution, bubbling and a strong smell of
ammonium should be present.
Using the remaining test tube, add 0.1 ml of HCl into the solution. Record your findings.

and encounters her previous lover, Alcee, whom she invites in her home out of the elements. After she voiced her concern for her husband and son during the storm, lightening frightened Calixta, and she shared her fear of the house being hit by lightning, Alcee held her for comfort. They spoke of past times together, as it was, the feeling of comfort leads to more than talking between them. Little did she know that by opening her house for shelter from a storm of nature, Calixta, opened herself…
Then I dipped it in the water. The next time we came the mine I tried the chisel for a while, however heat treating also makes the metal more brittle and after only an hour or so it shattered. Then I remembered that my blow torch was in the car, the melting temperature of copper was 1,984 F, and my blow torch could reach that temperature. I ran outside grabbed my blow torch and held the flame up to one of the chucks holding it the wall. Twenty minutes later one of my friends shout “Jon! HEY…
When flame test research is performed on an element, it is easy to see the color changes just by physically observing it. Often, many elements can have similar emission spectra’s, which is why Kirchhoff invented the Spectrometer. This is a specialized device that uses a prism and two mirrors that allow the light to be conducted into its unique emission spectra.
From elements such as lithium to others like selenium, every single element has its own unique color or elemental fingerprint; this is…
Prometheus was constantly at odds with Zeus, and endured severe punishment for giving fire to humans. Zeus punished Prometheus through humankind as well, by indirectly unleashing all evils on the world. Symbolism related to Prometheus can be found in fire, the colours of fire, punishment, trickery, forethought or intelligence, progress, rebellion, garlands, and camaraderie. Prometheus is perfect to endorse “Fight-Me-Not Flames” because he has gone through hardship that could have been avoided…

Title: Gunpowder QPOEE
Which amount of Sulfur(.25 grams, .5 grams, .75 grams, and 1 gram) creates the closest reaction with fire as the store bought gunpowder in terms of size of flame and the time duration of the flame?
The equation for the reaction of our gunpowder is 10Na NO3 + 8C + 3S → 2 Na2 CO3 + 3Na2SO4 + 6CO2 + 5N2. This shows that Sodium Nitrate is reacting with…

1. Set up the equipment with the Bunsen burner and tripod on the heatproof mat with the gauze on top of the tripod.
2. Add the seaweed to the tin lid and place on top of the gauze (try not to use any ‘pods’ of seaweed as they pop when heated which could be dangerous). Light the Bunsen burner and…
