  • Pros And Cons Of Death Punishment

    The lethal gas first in place in 1920s in Nevada. The first execution by this method was Gee Jon (1924) and contemporary Walter la Grand (1999). lethal gas replace the electric chair modest method. process by this method follow the same across the board. The offender is strap down to a chair in a airtight compartment. A long stethoscope is place to confirm the heartbeat and have a. Warden will signal the excursionists release sodium cyanide crystal to a container. A chemical reaction will released hydrogen cyanide gas then the inmate must take deep breath.. the cause of death is loss of oxygen (hypoxia) to the brain. Fan then ventilate the poison gas from the chamber. The body will sprayed to neutralized any remaining cyanide. Execution team with mask and gloves will check and remove the body. the similar to the lethal gas they are complication with this process as inmate do not follow order to deep breath they prolong their execution. unlike the lethal injection this the lethal gas will take ten to twenty minutes to complete the process. In the use of lethal gas they are health risk by any escaping gas and maintenance of the chamber. The lethal gas lost its humane nature by the knowledge of concentration camps in Nazi Germany. It seem cruel and painful to carry out. The earliest history record of lethal gas started…

  • Nazi German Experiments Essay

    Different Countries, Same Crimes “Monsters exist, but they are too few in number to be truly dangerous. More dangerous are the common men, the functionaries ready to believe and to act without asking questions” (Primo Levi). There are common people every day who experiment; however, experiments turn evil when they prove genocidal to races. Throughout history, there have been events which most would like to change or forget; likewise, there are events which are repeated, even though the event…

  • Importance Of Coordination Compounds

    They can control biological processes. For instance, • carboxypeptidase is an hydrolytic enzyme important in digestion, contains a zinc ion coordinated to many amino acid residues of the protein. • Another enzyme, catalase, which is an well-organized catalyst for the decomposition of hydrogen peroxide. Because it contains iron-porphyrin complexes. In both cases, the coordinated metal ions are probably the sites of catalytic activity. • Other coordination compounds in biological systems…

  • Ammonia Research Paper

    a compound composed of nitrogen and hydrogen, having the formula NH3. The ammonia molecule is formed by sp3 orbitals as it has a tetrahedral geometry and a trigonal pyramidal shape. Ammonia has an experimentally determined bond angle of 106.7°, and an a bond length of 101.7 pm. The nitrogen atom in the molecule has a lone electron pair, which gives the molecule a dipole moment and polarity. Ammonia’s lone electron pair makes NH3 a base, a proton acceptor, and gives it the ability to readily…

  • Photocatalyst Analysis Of Tio2

    Since the water splitting reaction using semiconductor electrode reported by Fujishima et al. in 1972 [1], there is increasing interest in the development of metal oxide photocatalysts for environmentally friendly applications such as air purification [2], hydrogen production via water splitting [3] and the removal of organic molecules from water [4]. Recently, photocatalyst thin film has aroused growing interests instead of a powder type of photocatalyst. Photocatalyst film can be deposited…

  • Essay On Alkanols

    INTRODUCTION Fuels are hydrocarbons that when burnt release carbon dioxide gas, and liquid water. A hydrocarbon are fuels which consist of only carbon and hydrogen atoms, the three main types of hydrocarbons are alkanes, alkenes, alkynes. Alkanes consist of hydrocarbons in which all bonds are single bonds, hence meaning that Alkanes are saturated molecules as they contain the maximum number of hydrogen atoms available to bond with the carbon atoms, the simplest of the alkanes, being methane as…

  • What Is Laccases?

    What is a laccase? Laccases (EC 1.10.3.2, benzenediol: oxygen oxidoreductase) are monomeric, dimeric or tetrameric glycoproteins that are typically extracellular and categorized as multi copper oxidases (Mate and Alcalde, 2016a).They catalyze the oxidation of compounds that are coupled with the four-electron reduction of "O" _"2" "to" "H" _"2" "O" . They are regarded as eco-friendly enzymes. Laccases have been first discovered in 1883, which makes it one of the oldest enzymes ever observed…

  • Iodoform Test

    oxidation products of alcohols. Depending on the alcohol’s structure, the product obtained will be different. Primary alcohols have one carbon and two hydrogen atoms attached will produce aldehyde and then to carboxylic acid in two steps by oxidation. While secondary alcohols have two carbon atoms and one hydrogen atom attached will produce ketone by oxidation (Kotz, et al., 2015) Aldehydes, the compounds that the carbonyl group has a hydrogen atom attached to it together with either a second…

  • Tin And Sulfur

    The unique composition and purity of as-deposited SnS2 thin films prepared with different precursor solution volumes from 5 ml to 25ml were determined by EDX analysis as shown in fig 5, which brought out the presence of Tin and Sulfur as elementary components. Two different peaks were observed in the spectrums from fig 5 relevant to the tin and sulfur. The EDX spectra show that the weight percentage for the film prepared at the precursor solution volume of 5 ml is 36.8% and 63.2%, which is…
