A few metal elements in high temperatures may enter an excited state and they’re seen by emitting a light of color. Comparing the substance flame with the flames of the reference table will help identify the element of the unknown metal. First we placed each of the liquefied metals in flames and observing their color changes by collecting data. Lastly, observing the color of the liquefied metal, placing it in the flame with a wire loop could emit a color change and this concludes the experiment. The unknown metal was exactly the metal ion that was hypothesized. The unknown metal

In the context of this document, it refers to the turning motion of a proton). Hydrogen nuclei also possess a magnetic moment M (a magnetic field created by the moving positively charged protons) that has its origins in circulating currents. This means that there is always an angular momentum J associated with it. The vector quantities M and J are related by the equation: [IMAGE][IMAGE][IMAGE]M = gJ [IMAGE] Where M = magnetic moment g

First, the normalized freezing points for unknowns 3 and 4 were -2.8 degrees Celsius and -3.0 degrees Celsius, respectively. The van’t Hoff factor was one because the solid does not break apart, and it remains as one particle. The molalities were 1.505 mol/kg for unknown 3 and for unknown 4 it was 1.613 mol/kg. In the second step, the unknown number of moles of each unknown was determined by using molality. This was calculated by dividing the molality determined in step one by 20 mL of water solvent.

I am a non-metal so I have low conductivity, am brittle, and conduct heat. My melting point is -346.00 degrees Fahrenheit (-210.00 degrees Celsius) and my boiling point is -320.44 degrees Fahrenheit (-195.79 degrees Celsius). My density is 1.2506 x 10-3 g/cm3 and my atomic weight is 14.0067 amu. I am found in the p block, have two energy levels, five valence electrons, and an electronegativity of 3.0. I can also be found in the form of liquid nitrogen, which can be used for refrigeration for food or as a preservation device on dead bodies or reproductive cells. However, there are also forms of me that are bad for the environment such as nitrite and

As magnetite is well-researched, multiple factors influence the formation of iron oxide magnetosomes have been identified. The most important factors are the presence of oxygen, and substrates in the form of nitrogen oxides (Bazylinski 2004). MORE

Furthermore, in this experiment we learned that NMR takes advantage of the magnetic properties of the 1H and 13C nuclei. We are not concerned with 12C because it does not have a magnetic

Ferrofluids are nanoscopic shards of magnetic particles suspended in organic fluids or water. What are the modern potentials and applications of ferrofluids? Ferrofluids have current applications in a variety of fields and continue to have potentials for further advancements in others. With research of the first ferrofluid in 1963 by Steven Papell with N.A.S.A., ferrofluids have been used to provide advancements in the field of technology. In modern times, ferrofluids are used in speakers for their relationship with magnetism and heat; as well ferrofluids are used in computer hard drives for their unique magnetic fluidic properties. Additionally, ferrofluids have potentials in the field of bio-medical engineering, including: advancements
