Atomic Line Emission Lab
The emission spectrum of a chemical element is the spectrum of frequencies of electromagnetic radiation due to an atom or molecule making a transition from a high energy state to a low energy state. There are a lot of electron transitions for each atom. All transitions have a energy difference.
After doing the atomic line emission lab my results came out in many different ways. During the lab, we went to five different stations. Throughout the stations, the light that we used to figure out the quantization changed. In the first station that I went to there were many gaps in the spectrum. I saw red, orange-yellow, a little bit of green and blue, and velvet. From seeing this color, I chose “Rh” as the element because it matched the color spectrum

After the recording, the cuvette was removed from the SpectroVis and the content was poured back into the original volumetric flask. The absorbance as well as the maximum wavelength of each solution was recorded in Table 3 and

831 Words | 4 PagesUnit D Summary: Light and Geometric Optics 10.1 : Light and The Electromagnetic Spectrum Chapter 10.1 covers light and the electromagnetic spectrum. This chapter starts off by describing how light is a form of energy that travels in waves. The properties of said waves include a crest (the highest point of the wave), the trough (the lowest point of the wave), and the rest position (the level of a wave without energy).
Hastings Point Lab Report
1610 Words | 7 PagesIntroduction For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.
Sodium Chloride Lab
896 Words | 4 PagesThe purpose of this report is determine if sodium chloride is a viable option as a deicer on winter roads. To determine this, one must compare a multitude of factors. In this lab, the freezing point depression of water, enthalpy of dissolution, cost, and environmental impact will be discussed. A large factor in how effective a substance is as a deicer is it’s ability to decrease the freezing point of water. If the freezing point of water can be lowered, the outside temperature must be much colder to reach this new freezing point, resulting in less ice on the roads.
Snapthene Lab Report
699 Words | 3 PagesBy looking at our results, even though my partner and I didn’t obtain a high percent recovery for the unknown, we were still able to identified our unknown to be Acenapthene. We know that our unknown B8 is Acenapthene because of its melting range and its color. The unknown B8 was similar to the color of Acenapthene, and the mixed compound (Acenapthene and the recrystallized compound)’s melting range was close to Acenapthene’s literature melting range. With these two points, my partner and I believed our unknown B8 to be Acenapthene. According to our recrystallized vanillin, we know that our vanillin was pure because of its melting range.
Beanium Isotope Lab Report
450 Words | 2 PagesBeanium Isotope Lab Introduction: Isotopes are explained as the variations of the number of neutrons that an element may have. Some isotopes are more common than others. This experiment was performed to help visualize the different isotopes of an element and show how some isotopes will appear more often than others. Purpose: To visualize and understand isotopes Materials: Refer to Lab Sheet “Isotope Experiment- Beanium”

A random error would be that there was a logger pro used the second day as there was no go link present as it had been the previous
6.03 Calorimetry Lab Report Honors
330 Words | 2 PagesThe observed emission data for the different elements did not look how they were supposed to. However the “peaks” for Hydrogen were found to be 534.52 and 631.24, 534.70 and 569.11 for Helium and 529.73 and 630.71 for Mercury. The Rydberg’s Constant found to 1.1x107 8.5x104 while the known constant is 10967758.34m-1. The percent error of 0.29% and the accuracy of this reading is 99.7. The slope and intercept of the linear regression line is -0.01 3.3x10-5 and 0.02x10-1 1.9x10-6 respectfully.

Lab Report Spectrophotometry Lab
851 Words | 4 PagesHowever, any doubts regarding the results may be traced to a few elements of the experiment that lend themselves to possible error. The following factors may have contributed to potential errors in the experiment; the need to zero the machine between each of the readings in obtaining the absorption spectrum and the resulting peak wavelength, the precision with which a person can accurately adjust the needle on the spectrophotometer to zero is limited, not putting in the inaccurate amount of cobalt chloride or water into the substance, and getting oil from our fingers onto the
Radiative Zone Lab Report
214 Words | 1 PagesComprising 45 percent of the sun’s radius, the radiative zone extends outward from the core, and the energy from the core is carried outwards by photons. A photon travels around one micron (one millionth of a metre) as it is made, before being absorbed by a gas molecule. As it is being absorbed, the gas molecule heats up and re-emits another photon of the same wavelength. This exact cycle is repeated once the re-emitted photon travels another micron before being absorbed by another gas molecule. Before a photon reaches the surface, about 1025 absorptions and re-emissions take place, which means there is a significant time delay between a photon made in the core and one that reaches the surface.

Laser light has tight beam and is strong and concentrated. To make these three properties occur takes something called “Stimulated Emission”, in which photon emission is
