Hydrogen sulfide

ABSTRACT Within this experiment, the use of a bomb calorimeter was required in order to determine the heat capacity of the system through the combustion of three separate trials of benzoic acid. The resulting heat capacity values for each trial were averaged, with a standard deviation found as well. This was then used to work backwards, for a naphthalene trial, in order to calculate the change in energy (∆U) and the change of enthalpy (∆H). The accepted value for the change in enthalpy of…

of the compounds Germanium is in is Germanium hydride. Compounds don’t have symbols but they have formulas. Germanium hydride’s formula is GeH4. The 4 represents the subscript. A subscript is how many parts it is, so Germanium hydride is 4 parts hydrogen and 1 part Germanium. The uses for germanium are camera lenses, semiconductors, fluorescent lamps, and alloys. Germanium has a total of twenty five isotopes and only five are stable. Germanium’s compounds can cause pain and redness to eyes and…

Buoy 21, Day Mark 1, Pelican Island Cut, and the Coast Guard Station. The main ingredient in saltwater is water. Water is composed of two hydrogen atoms and one oxygen atom that are covalently bonded and forms a polar molecule because the electrons are shared unequally. The unequal distribution causes the oxygen atom to have a negative pole and the two hydrogen atoms have a positive pole. The polarity of water makes it unique and allows it to perform as a solvent (Duke University, n.d.). Since…

different products: 1-heptene, Cis-2-heptene and Trans-2-heptene. However, the major product constituent was 1-heptene. Because Potassium TertButoxide is a bulky base, steric hindrance prevents it from attacking a hydrogen on a highly substituted carbon. Consequently, the base attacks a hydrogen on the least substituted carbon (primary carbon). In this case, steric hindrance is reduced and the elimination reaction is faster, so a less substituted alkene is more favored, and becomes the major…

Step (1a) include only dispersion forces, because each of the compounds are non-polar. In Step (1b), there are dispersion forces, hydrogen bonding, and dipole-dipole forces. Dispersion forces occur in all compounds, hydrogen bonding occurs between the oxygen and hydrogen atoms within each of the compounds, and there is also a dipole movement between the oxygen and hydrogen atoms. There is a correlation between IMFs and volatilities, as the stronger intermolecular forces tend to evaporate the…

chlorosulfite then reacts with a nucleophilic chloride ion, at which point the chlorosulfite leaves in the form of sulfur dioxide and chloride ion. The remaining acid chloride then reacts with diethylamine. Diethylamine is used in excess to neutralize the hydrogen chloride produced in the reaction. The lone pair of electrons on the nitrogen atom performs a nucleophilic attack on the carbonyl carbon, while a pair of electrons in the double bond is pushed to the oxygen atom. When an electron pair…

Neon is one of the world’s rare and most expensive elements. I chose Neon because of it's uniqueness. In 1898, William Ramsay and Morris Travers at University College London isolated krypton gas by evaporating liquid argon. They had been expecting to find a lighter gas which would fit a niche above argon in the periodic table of the elements. They then repeated their experiment, that time allowing solid argon to evaporate at a slow pace under reduced pressure and collected the gas which came off…

changes in the number of neutrons in the nucleus. Some examples of isotopes are Protium, Deuterium, and Tritium, which are all Hydrogen atoms. Instead of the zero neutrons Hydrogen has in its Protium form, Deuterium and Tritium have two and three neutrons respectively. This change in neutron number and therefore atomic weight classify these atoms as isotopes of the element Hydrogen. An ion is an atom with a charge due to changes in the number of electrons (negatively charged particles) in the…

shiny before being put in. After being placed in the acid, the metal was much less shiny and weighed less. The acid was eating away at the zinc coating on the surface of the metal causing the solution to bubble vigorously, indicating that a gas (hydrogen) was being released. This was the corrosion taking…

Trend The constant, 0 v/v % hydrogen peroxide solution, did not react with the catalase, therefore it was recorded as 300+ seconds and had a reaction rate of 0 seconds-1. The 0.1 v/v % hydrogen peroxide concentration recorded a reaction rate of 0.17 seconds-1. The 0.2 v/v % hydrogen peroxide concentration, recorded a lower reaction rate than the 0.1 v/v% at 0.14 seconds-1. The 1 v/v % hydrogen peroxide concentration recorded higher at 0.49 seconds-1. The 3 v/v % hydrogen peroxide concentration…
