is added to an atom‚ electrons jump from their ground state to their excited state. When they return to the ground state‚ they release the excess energy that they have absorbed in packages of light called photons‚ or light quanta. The characteristic light emitted by each individual atom is the basis for the chemical test is known as the flame test.”-Gilbert Procedure

The night was dark. The sky was only lit by a full moon and a few faint stars. I was sitting quietly in my basement with my sister and two of our friends‚ Danny and Heather. We were all feeling rather bored. I came up with the idea to go get my Ouija board from my room. I told everyone‚ "I’ll be back in a minute." I ran upstairs to my room‚ grabbed the Ouija board from under my bed‚ and quickly ran back down to the basement. I set the board up and got the oracle out. Everyone had this odd look on

This excites electrons causing them to gain energy. As the electrons gain energy they are moved into higher energy levels. Naturally‚ electrons want to move back to their original state. As the electrons move down from higher energy levels‚ a photon is emitted. A photon is a particle of light. The absorption of energy‚ and the energy of the energy emitted is quantized. Electrons can take one big step as it reaches its base state and release one photon. Electrons

acid‚ 0.8 mL of glacial acetic acid‚ and 1.0 mL of 1.0 M of Bromine in acetic acid was recrystallized to form a solid‚ clear‚ crystal- like product. The melting was taken from the recrystallized product to determine what had been obtained. The melting point was found to be 130.5°C-133.7°C. Concluding that the product formed from the addition of bromine was a mixture of the erythro-2‚ 3-dibromo-3-phenylpropanoic acid‚ which has a known melting point of 204°C‚ and threo-2‚3-dibromo-3-phenylpropanoic

Night essay The book Night was an autobiography of Eliezer Wiesel. This was a horrible story and sobering tale of his life story that shows a lot of dehumanization. Hitler with his army of Nazis brought down many group of different people but the ones that were treated the worse where the Jews. Mobs took over their homes and business. The memories of night has lots of examples. To begin with “veteran prisoners needles in hands‚ tattooed numbers on our left arm’’ (42). To not be able to be called

A Night of Music A night of Music at the Dunham theatre‚ the first piece played at the venue was a wonderful piece by Gustav Holst called Second suite in f. Starting off very subtle and with a sequence that continues throughout the whole piece. As the brass and percussion make entry the pitch of the winds dim down while the others increase making the dynamics of the music vary from a very delicate to very strong when the percussion and brass sections start playing. It’s melody had a very folk tune

Night Essay Eliezer was one of the few survivors of the Holocaust and his experience left him thinking what compelled Hitler to do this‚ what stopped people from helping them? Many people think that hatred is responsible for the events in the book Night‚ and the Holocaust but in reality indifference was responsible for what happened. The indifferences that were the main causes of the Holocaust were how the Jews felt about the Nazis and God‚ how the townspeople felt‚ and how the Jews dealt

------------------------------------------------- RESULTS AND DISCUSSION A. Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment required centrifugation of the solution. This was done to completely separate the precipitate from the supernate
