Helium

The structure of a molecule affects how it is able to bond with other molecules and how effective these bonds are. The structure of the molecule itself is held together by the intramolecular forces, which are the internal forces of a molecule, such as the attraction and repulsion of electrons to the protons in the nucleus. The external forces on a molecule, which are called the intermolecular forces, such as electronegativity, help to determine the boiling and melting points of each element.…

Weapons and Technology of WW1 World War I was called “the war to end all wars;,” however, it didn’t end anything. World War I was the biggest war anyone has ever seen in their time. Some countries were crippled, and some countries were strengthened, the same can be said of families. Over 38 million people died during this horrendous conflict, most of these deaths were civilians. Philippians 3:13 says, “Brothers, I do not consider that I have made it my own. But one thing I do: forgetting what…

cooled and solidified into the planets. A problem with the Planetesimal hypothesis is if the star passing by was larger than the Sun, why did it only take pieces instead of the whole Sun? Also, if the material pulled from the Sun was hydrogen and helium based, then how did solid rocks form the planetesimals? Although all of these hypotheses are different, the also share some similarities. The Nebular and Protoplanet both start the process with a cloud that will eventually spin. Also,…

seen with the naked eye. Saturn is the second largest planet and is best known for its fabulous ring system that was first observed in 1610 by the astronomer Galileo Galilei. Saturn is a gas giant and is composed of similar gasses including hydrogen, helium and methane. Saturn can be seen with the naked eye. It is the fifth brightest object in the solar system.Saturn was known to the ancients, including the Babylonians and Far Eastern observers. Saturn is the flattest planet. Its polar…

particle (protons). At that time atoms were thought to be made up of protons and electrons (The Experiment - Chadwick Experiment). The particles given off by from Beryllium had no charage and was little larger mass than a proton. Alhpa particlces are helium nucleus emitted by some radioactive substances, known as rays. Shown in the figure on the…

worked is way to becoming a Michelin 3 star chef. His tale is truly one of woe and triumph. Through my research, I have seen him cook things that both confuse and astound me. From his elegant Milk chocolate Pate sucree, to the almost mystical Balloon, Helium, green apple each dish had me at a loss for words. Grant started off working at his parents restaurant in St. Clair Michigan as a young lad. He then continued his culinary career by enrolling at the culinary institute of America, a pretty…

daughter’s brains. I walked and walked for hours- Rosie won’t stop crying. I enter a residency trying to find some survivors. I found a birthday party that was cut short. I showed her a birthday hat she won’t stop crying. In front of me there was a helium tank, I inserted a pink balloon on the nozzle, and it inflated. Rosie giggles- it’s so cute how she giggles. I continued my adventure until a pain hits my chest like venom. Everything in my eyesight was just blurry, I’m dizzy, and I can…

The purpose of this spectroscopy experiment was to determine if the spectra matched the electronic transitions that occur in the hydrogen atom among several other atoms. We used the Bohr model of atomic structure to determine the orbit numbers that correspond with the spectrum emitted by the hydrogen atom. The Bohr model states that electrons will never be found in between states, but rather completely in one state or the other. We used this model to determine the initial n value at which the…

Esters have a very sweet fruity smell. Esters are commonly used in the preparation of artificial flavors or fragrances. Flavors and fragrances may utilize a single ester or a mixture of esters and other substances to duplicate the odor and flavor of a particular fruit. Naturally occurring esters are found in fruits. An ester is a product of the reaction of an acid (carboxylic acid) and an alcohol (the hydrogen of the acid R-COOH is replaced by an alkyl group R'). Esters mainly result…

thermosphere can also expand when there is high incoming solar radiation absorption. The air density and air pressure in the thermosphere is very low. In this layer of the atmosphere the main gases in the air is atomic oxygen, atomic nitrogen and helium. The reason why it is atomic oxygen and atomic nitrogen is because the gas particles don’t collide with one another often and become separated. This is also the layer where the Northern and Southern lights, or the aurora, take…
