cName: Nicholas Cassel Gen Chem 1210 23 March 2013 Blinded By the Light Abstract: In this experiment we were provided a cereal box spectrometer to observe the emission lines of noble gases and hydrogen. Based on the scale readings on the spectrometer and the Balmer-Rydberg formula‚ their wavelengths and percent error were able to be extrapolated. Based on the literature values‚ the cereal box spectrometer proved its value as a decently accurate spectrometer. Introduction: Every element

symbol of letting him go his mother‚ father‚ sister and his lover Cal‚ let a white helium filled balloon go into the air. The white helium balloon symbolizes Andre’s departure and represents his spirit rising to heaven. “They represent the soul. When you let it go‚ it means you’re letting his soul ascend to heaving” (Cal page 737). Cal‚ the main character and Andre’s mother have the toughest time letting go of the helium balloons while Penny (his sister) and Andre’s Father let go of the balloons with

The Life of High Mass Stars High mass stars can be classified as any star that is at least four times the solar mass of our star‚ the sun. They consist of about three percent of all of the stars in the universe‚ but there are still billions and billions of them all over the universe. High mass stars‚ like low mass stars‚ begin to form from clouds of gas and dust in space. They both begin as a protostar and eventually become dense enough to cause hydrogen fusion within them; placing them both on

occur in which hydrogen fuses to form helium. The star then begins to release energy which stops it from contracting‚ and it causes the star to shine. When a star starts to shine it is called a "main sequence star". A star remains in main sequence depending on its solar mass. A star of about 1 solar mass will remain in main sequence for about 10 billion years. After all of the star’s hydrogen has been used to form helium‚ it begins to cool down and the helium fuses to carbon and the star expands‚

immiscible solute and solvent are illustrated at right. Helium–oxygen mixtures are sometimes used as the breathing gas in deep-sea diving. At sea level (where the pressure is 1.0 atm)‚ the solubility of pure helium in blood is 0.94 g/mL. What is the solubility of pure helium at a depth of 1500 feet? Pressure increases by 1.0 atm for every 33 feet of depth‚ so at 1500 feet the pressure is 46 atm. (For a helium–oxygen mixture‚ the solubility of helium will depend on its initial partial pressure‚ which

Which statement below would be true about the masses of the two gases (after adjustment for the buoyant effect of air)? A. The mass of the helium would be 1/9th that of argon. B. The mass of the helium would be 1/10th that of argon. C. The mass of helium would be 9x that of argon. D. The mass of helium would be 10x that of argon. E. None of these answers are correct. 4. 36.0 g of Be contains how

an early creation is that there is too much helium in radioactive rocks. Helium is found in uranium and thorium during their radioactive decay. This helium quickly leaks out into our environment.. Helium leaks out faster if it is found in very hot situations‚ that means the deeper the rocks are in the earth the less helium they should have. Actually‚ helium diffuses so fast it should have been gone in 100‚000. Geologists in New Mexico found more helium in rocks that were 197 ℃ than they had

piter. Main Sequence: Most stars in the universe for most of their life will fall into the category main sequence. A main sequence star is when a protostar is able to begin nuclear fusion‚ in the core of these stars hydrogen is fused into helium releasing energy in the process. Main sequence stars vary in size from around 0.08 the mass of our Sun (this is known as a solar mass) to 150200 solar masses In general the bigger a star is the faster it uses Hydrogen and the shorter it’s lifespan

Chemistry 2500- Exercise C4 The Emission Spectrum of Atomic Hydrogen Objective The purpose of this lab was to calculate an experimental value for the Rydberg constant and then the ionization energy for the hydrogen atom. These values will be obtained by using a prism spectrograph to measure the wavelength value for a section of the visible line spectrum of atomic hydrogen. Theoretical Background When H+ combines with an electron it forms it’s excited state‚ H. This excited atom

This is what exactly what defines lightens our planet today. Later when the hydrogen gets absorbed into helium‚ there is no more energy which will empower it to push out and block the Sun from being diminish. In the end the Sun would
