Hydrogen cyanide

Known for the method used in industry to synthesize ammonia from nitrogen and hydrogen gases, Fritz Haber was, and still is, a well-known German chemist whose invention is used today for the production of fertilizers, cleaning products, and explosives. He was born on December 9, 1868, in Breslau, Prussia. Three weeks after being born, his mother passed away due to the toll her pregnancy took on her, thus leaving him to be raised in a Jewish household by his father, Siegfried, and several of his…

The purpose of experiment 02 is to separate two solid compounds, benzanilide and thiourea, from a crude mixture, then verify the purification. The experiment is to be broken down into several stages: (a) In order to perform small-scale recrystallization, a suitable solvent must be selected. (b) The actual small-scale recrystallization is performed on the benzanilide-thiourea crude mixture. (c) Filtration of purified crystals. (d)Product recovery is calculated and measured. (e) In order to…

The Law of Conservation of Mass is a system where an isolated system cannot be created or destroyed by a chemical reaction or physical transforms. (from the website: https://courses.lumenlearning.com/introchem/chapter/the-law-of-conservation-of-mass/).The Law states that mass of products in the reaction must be equal to the reactans or the things that causes the reactants.Again from the same website.The History behind it is that the Greeks were the first to come up with the idea,but it wasn’t…

Lab 9: Preparation of an Iron Oxalate Complex. POST-LAB: RESULTS AND DISCUSSION 1. Write a brief summary of your experiment. The experiment was conducted by creating a K3Fe(C2O4)33H2O solution using DI water, 3.501 g of iron (II) ammonium sulfate, H2C2O, K2C2O4, and H2O2. 5 ml of ethanol was dispensed within the solution to aid in the crystallization of the oxalate. The results of the experiment did not provided crystals of the oxalate rather crystals of impurities formed within the solution…

The results collected illustrate that cyclohexene is the unknown. Comparing the measured boiling point of cyclohexene to the literature value of cyclohexane, there is only a difference of 0.3°C. Comparing the measured density of cyclohexene to the literature value of cyclohexane, there is only a difference of 0.027 g/mL difference and comparing measured refractive index of cyclohexene to the literature value of cyclohexane, there is only a .009 difference. All of these results shows that both…

In problem one, we were simulating an ammonia production by reacting nitrogen and hydrogen in a reaction called Haber process. Haber process is a very economic exothermic reaction to produce ammonia by reacting nitrogen and hydrogen using a metal catalyst in high pressure and temperature. Nitrogen was obtained from the air and therefore, some argon would be included in this simulation. On the other hand, hydrogen was obtained from the cracking of petroleum. The simulation process started where…

The aim of this research is to determine the impact that AMD has on the…

Reaction #2- A few little bubbles when the Mg Dioxide combined with the Hydrogen peroxide. Reaction #3-A pop noise occurred appeared in the Test Tube with the combination of the Solid Zinc and Hydrochloric. Reaction #4-A gas substance came from the Test Tube with the mix of Copper (ll) Sulfate and Sodium Hydroxide. Conclusion:…

In this experiment, pinacol was mixed with sulfuric acid, which protonated the pinacol, allowing it to form a better leaving group. Water is the leaving group off of the pinacol and the pinacol becomes a carbocation. The carbocation that is formed is a secondary carbocation so, rearrangement occurs. A methyl shift happens to form a tertiary carbocation, which is more stable than a secondary carbocation. Then, the remaining oxygen forms a double bond causing it to have a positive charge; allowing…

4.3.3. Binary mixture toxicity of As, Cd and Pb All the three metal mixtures (As + Cd, Cd + Pb and As + Pb) displayed synergistic response at the 10% level and strong synergism was observed for the mixture of As + Pb with CI value of 0.25. The observed synergism was extended up to 30 and 50% level for Cd+ Pb and As + Pb mixtures, respectively. The binary mixture of As + Cd showed an additive response at the 30-50% level. All the mixtures showed an antagonistic effect at the IC90 level and the…
