doing a flame test. During Part A‚ we used a spectroscope where all of the colors are arranged for you; whereas in Part B‚ we could see and make the colors ourselves and get a more accurate reading of the flames. We had specific elements we were told to put on the wire loop‚ and when we did that we saw different color flames come out of the Bunsen burner. That enabled out group to see the element in an excited state. The unknown element was lithium. This is known because if the color of the flame produced

be regulated until the flame has the desired height. If a very low flame is needed‚ the ports should be kept partly closed when the gas pressure is reduced. Otherwise the flame may "strike back" and burn inside the base of the barrel. If this happens‚ turn off the gas‚ decrease the amount of air admitted‚ and re-light. Part II LUMINOUS FLAME Relight the Bunsen burner. Close the airports or inlets as completely as possible and note the color and shape of the flame which is now luminous.

You hang by a slender thread‚ with the flames of divine wrath flashing about it‚ and ready every moment to singe it‚ and burn it asunder; and you have no interest in any mediator‚ and nothing to lay hold of to save yourself‚ nothing to keep off the flames of wrath‚ nothing of your own‚ nothing that you ever have done‚ nothing that you can do‚ to induce God to spare you....

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
