Some compounds have very distinctive colors when burned, such as Potassium, which is a white/purple, and sodium, which is a deep red hue. The first step for a flame test is to gather the needed materials. These include beakers, distilled water, the unknown substance, a Bunsen burner, matches, a nichrome wire, tubing to connect the gas line to the Bunsen burner, goggles, and known compounds to compare with. The first step is to make aqueous solutions of all the substances to be tested. This is done by adding .5
The 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.
2.03 Electromagnetic Spectrum- The Visible Assignment 1. A Doppler radar can see the amount of precipitation that there is in a thunderstorm. It can also see the direction of the precipitation in a thunderstorm as it moves closer or away from the radar.
Flame Tests of the Elements Lab 1. According to your observations, which metal ion is present in your unknown samples? Explain your rationale.
As soon as possible this new gas was put into their atomic spectrometer and they were amazed with the results. It began to glow a vivid orange-red color! (Heiserman, 1992) a “As Travers wrote, ‘the blaze
1. For the unknown light source, it had almost every color, so it might have been be mercury because they have similar color beams and their color from the naked eye appeared as purple, which mercury, a light blue, is very close to in terms of it's color from the naked eye. For the unknown flame crystals, it may NH4+ because the colors that appeared are very similar to the crystals. 2. Chemicals have to be heated in the flame for the color to emit because heat adds energy to the substance making the electrons more excited, allowing for the electrons to transition faster. 3.
Introduction: In this lab, we measured the angular velocity of the sun (how fast the sun rotates on its axis) to find the time it takes for the sun to make a complete orbit. We did this by printing two images of the sun that are 7 days apart from NASA’s SOHO database to observe and measure one sunspot (the same sunspot in different locations on both images). We looked at sunspots because its dark (due to magnetic activity and heat transfer) and easy to identify since there are few spots from a faraway perspective. were able to solve for the time period it takes for the sun to rotate on its axis using the following formulas: θ=sin〖x/(R ')〗 where R’ is the radius of the circle the sunspot orbits, 〖θ=sin〗〖x/R_sun 〗 , where R_sun is the radius
In this experiment, the elements copper, cobalt, barium, sodium, lithium, and strontium were burned to see the colors which they produce. Each flame was a distinct color and burned at different speeds, meaning that my partners and I had to repeat the step of burning the element several times in order to get precise results. The experiment was mainly conducted to see the light spectra that the colored flames cast, and to become acquainted with using spectroscopes. One of the elements used in this lab, lithium, is used to make batteries and as medicine, but also gives of a red color. In order to get good results, the lights in the lab were turned off, this way my partners and I could more clearly see the color of the flame and the lines which
Advanced Biology Photosynthesis Lab Report By Cheryl G11 Introduction & Background Photosynthesis is the process by which light energy is converted to chemical energy. It occurs within each chloroplast in most of the green plants, and Carbon dioxide is one of the main components of this process. Plants use photosynthesis to produce their own food (glucose), some water and the oxygen that we need.
If there is no change of colour from the flame, make the substance into a solution by adding deionized water to the unknown metal to make a solution 5. Note the solution colour 6. If the solution is colourless perform the hydroxide test 7. Record your results 8. Now use carbonate test to find out if it is a carbonate 9.
Introduction Purpose The purpose of this star intensity investigation is to determine how the apparent brightness of a star is affected by the distance between the star and the observer. Background Information Stars are large spheres composed mainly of hydrogen and helium gas located in space. Due to their incredibly high temperatures, and fast particles, a process called nuclear fusion occurs within them. Nuclear fusion is when two atoms, usually hydrogen atoms, collide within a star to create a single atom (usually helium).
Glow This tool adds glow auras on the picture. The effect finds the brightest are on the image and adds it bright halos. So it turns out that the brightest area shines. This effect is used to mitigate the general form of picture as well as to give it a "romantic" view or create a fog effect.
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.
The purpose is to determine if atoms with different elements contain similar amounts of energy. If group 1 elements are similar, then they will emit a similar source of light energy because the elements are similar when the electrons become excited they will emit the same color due to the similarities that they obtain (Pre-lab). In this lab we
