Hydrogen vehicle

oxygen, killing fish and other organisms which is crucial to the freshwater environment. Acid rain is a type of pollutant which has impacted the southern Appalachian Mountains. Acid rain is a level four on the pH level which measures the amount of hydrogen in a substance. This pollutant falls into our freshwater ecosystems, and kills many of the living organisms due to the high acidity in the water. Heavy metals are extremely dangerous and causes a multitude of problems for our freshwater. Lead,…

SAFETY ACTION PLAN Student’s name Prof’s name Course title Date Food distribution warehouse workers have been experiencing symptoms such as lightheadedness and dizziness. These symptoms are believed to result from conditions in the company; therefore, investigations are to be launched in order to identify the possible source of the symptoms. To identify the sources of the contaminations, several methods were used. Methods such as observing the workers as they worked,…

In the Acid-Catalyzed Hydration of norbornene, water and sulfuric acid were added to the C=C double bond to form norborneol. Sulfuric acid acted as a catalyst, where it was not consumed in the reaction and helped to propel the reaction forward, as it was vital in forming hydronium ion and breaking the double bond. Both the products endo-norborneol and exo-norborneol were synthesized; however regioselectivity and stereoselectivity played a role as to which product was more preferred and whether…

1. INTRODUCTION Graphene consists of single layer of carbon atoms arranged in a hexagonal lattice. It is the basic structural element of many other forms of carbon, such as graphite, charcoal, carbon nanotubes and fullerenes. In simple terms, graphene, is a thin layer of pure carbon bonded together in a hexagonal honeycomb lattice. It is the thinnest compound known to man, the lightest material known, the strongest compound discovered, the best conductor of heat at room temperature and also the…

Chemical Reactions I Purpose The purpose of this experiment was to test and see how four different chemical reaction worked. The four different chemical reactions are formation, decomposition, single-replacement, and double-replacement. The hypothesis of this experiment was that in each of the different reactions something would happen to the reactant whether it be color, mass, temperature, or pressure. II Equipment For this experiment Late Nite lab was used. In Late Nite Lab the equipment…

Paragraph 1 Iron phosphate structure with a symbol of FePo4, has crystal structures of FeO4 and PO4 as its tetrahedral links. There would be changes of this quartz type that can be determined by the neutron poly difraction between 294K and 1073K, according to Z. Kristallogr. While structural parameters of the iron phosphate depends on the temperature, whereby iron phosphate would be a beta-phase from an alpha-phase when temperature increases from low to high. Irregularity would also be…

example: Highly pure silicon for computer chips is produced through a displacement reaction. In this reaction, hydrogen reacts with silicon tetrachloride to form hydrogen chloride and release silicon. 4. Double displacement reactions: Double displacement reactions are those in which two compounds exchange ions to form two new compounds. For example: In the reaction of copper sulphate and hydrogen sulphide, copper sulphide and sulphuric acid are…

III. RESULTS AND DISCUSSIONS: A. Characteristics of Aluminum-Graphite composites and the in-situ reaction To examine the reaction condition of carbon flakes and Al powders, 4 wt. % carbon flakes were added to Al powders. Fig. 1 shows the DSC plot obtained during heating and cooling of the green compact from room temperature to 750 0C and from 750 0C to room temperature at a heating/cooling rate of 3 0C /min under argon gas atmosphere. From the DSC heating curve it is evident that the total…

When the drug within the liquisolid system is completely dissolved in the liquid vehicle, it is located in the powder substrate still in a solubilized state. Therefore they show improved release rate ,Thus, its release is accelerated due to its markedly increased wettability and surface availability to the dissolution medium(147). Figure…

Intermolecular Forces Intermolecular forces are the result of attractive or repulsive forces between atoms, molecules or ions, primarily as a result of electrostatic attractions; these forces act between discrete molecules. Intermolecular forces are weak forces but without them life as we know it would not be possible: water vapor would not condense into its liquid (or solid forms) if its molecules did not attract each other, and all matter, in fact, would exist as gases. The physical states…
