Ammonia (NH3) is a very imperative substance or product that is used day to day in everyone’s lives. Ammonia (NH3) is used to produce fertilizers, household cleaning products and is the starting material for many explosives and many pharmaceutical products. Ammonia (NH3) is also used to create nitric acid (HNO3), also a very crucial substance used in our daily lives. The Haber process is the industrial process for the manufacture of ammonia (NH3) from hydrogen (H2) and nitrogen (N2), if not for the Haber Process there would be massive shortage and impact of ammonia (NH3) in our lives, hence higher rate of famine and more time to clean household products and creation of pharmaceutical products, by which you can tell that the Haber process and …show more content…
Nitric acid (HNO3) is used in the production of ammonium nitrate (NH4NO3) and other nitrate based fertilizers. It is also used as a starting material for many explosives, like TNT or trinitrotoluene (C7H5N3O6). Nitric acid (HNO3) is also crucial for the pharmaceutical industry. Furthermore, it is used to produce certain dyes, which are used as food coloring, in the textiles industry and even as indicators. Royal water or aqua regia (HNO3+3 HCl) is a solution created by mixing one part concentrated nitric acid (HNO3) and three parts concentrated hydrochloric acid (HCl), which is used to clean glassware in the laboratory. Aqua regia is also used in the purification of gold and platinum. Very dilute solutions of aqueous ammonia (NH4OH) approximately ten percent w/v (weight per volume) are commonly sold as household cleaning …show more content…
For their efforts and contributions to developing large-scale industrial processes, they were awarded with Nobel Prizes in Chemistry. The chemical equation for the Haber Process is 3H2(g)+N2(g) 2NH3(g). The Haber process is the industrial process for the manufacture of ammonia (NH3) from hydrogen (H2) and nitrogen (N2). Hydrogen (H2) is obtained from the reaction of methane (CH4) and steam (H2O(g)), producing carbon monoxide (CO) as a byproduct. The hydrogen (H2) produced from this reaction also reacts with oxygen (O2) from air (N4O) producing water (H2O) and leaving nitrogen (N2) behind, recalling the fact that air consists of seven percent nitrogen (N2), twenty-one percent oxygen (O2) and two percent of other products. These gases are then compressed and delivered to the reactor where ammonia (NH3) is produced. These gases are then compressed and delivered to the reactor where ammonia (NH3) is produced. These gases are then cooled down, and ammonia (NH3) is liquefied, ready to be tapped off. Unused hydrogen (H2) and nitrogen (N2) are recycled back to the
Two solutions were prepared by using Calcium Nitrate Ca(〖NO_3)〗_2 with concentration of 0.101 M, Potassium Iodate KIO_3 with concentration of 0.100 M, and deionized water. First solution contained 25.0 mL of Calcium Nitrate and 25.0 mL of Potassium Iodate. In the second solution, 15.0 mL of deionized water were added with 10.0 mL Calcium Nitrate and 25.0 mL of Potassium Iodate. Each of these solutions was mixed for 15 minutes. After the reaction of the solutions took place, each of the solutions was filtered. To remove water liquid from the filtered solution, both of the precipitates in the
Hydration of alkenes is characterized by the addition of water and an acid-catalyst to a carbon-carbon bond leading to an alcohol. Dehydration is exactly the opposite in which dehydration of an alcohol requires water to be removed from the reactant. Equilibrium is established between the two processes when the rate of the forward reaction equals the rate of the reverse reaction. The alkene that is used in this experiment is norbornene. Through hydration of norbornene, an alcohol group should be present on the final product yielded what is known as exo-norborneol. Percent yield is a numerical indication of how much of the reactant was actually reacted to yield product. The equation for percent yield is shown below:

As shown in Fig. 5, the final pH of the NaClO-NH3 solution after simultaneous removal are 5.4, 6.9, 7.2, 7.5, 8.5, 9.6, 10.7, 11.5 and 12.8 with respect to the initial pH of 5, 6, 7, 8, 9, 10, 11, 12 and 13, from which, an interesting law can be concluded as that if the initial pH is an acidic, the final pH is slightly increased; but if the initial pH is an alkaline, the final pH is declined. NaClO-NH3 is macromolecule compounds with a large inter surface area. It contains abundant functional groups such as hydroxyl (OH), carboxyl (COO), quinone, amino (–NH2), etc, which determines that NaClO-NH3 is a salt of strong base and weak acid, as well the ionization equilibrium and hydrolytic equilibrium would be complicated. When the pH of the NaClO-NH3 solution was acidic, the functional groups such as OH, COO and NH2- would react with H+ to generate the NH3 sediment, resulting in a decrease of inter surface area owing to the block and a great loss of NaClO-NH3, then the NOx removal as well as the duration time was decreased. As for the increase of the final pH in the acidic conditions, this was a result of the consumption of H+ by NaClO. The decrease of the
Cu (aq) + 2NO3 (aq) + 2Na+ (aq) + 2OH- (aq) → Cu(OH)2 (s) + 2Na+ (aq) + 2NO3(aq)
After Hydrogen chloride (HCl) has been produced it is then siphoned off into containers filled with water therefore making Hydrochloric acid.
Most substances fall on a scale ranging from the most acidic to the the most basic with neutral substances falling somewhere in the middle. Scientists call this the pH scale. pH levels are measured in numbers,0 to 14. The closer a substance is to zero the more acidic it would be. The closer to 14 the more basic a substance would be.Now what defines an acid and a base, one might ask? There are three ways of defining acids, each singling out a specific property. The first theory is the Arrhenius Theory with states, that an acid is a substance that produces the ion H+ when in a water solution, while a base is a substance which produces the ion OH- when in a water solution. Examples of an Arrhenius acid are HCl and HNO3. Examples of an Arrhenius base are NaOH and AlOH3.
We have to emphasize the importance of memorizing certain names and formulas and some prefixes and suffixes that are used in building a system of nomenclature. From there on, it is a matter of applying the system to different names and formulas you meet. The summary all the ideas that will be presented in this essay help you to learn the nomenclature system.
There were many things that I learned in Module 7 . Some of them where: what is the difference between an acid and a base; what is pH; what is equilibrium, what is Le Châtelier’s principle; and what is oxidation. Here are some of the things that I learned in lesson 07.01 (Acids and Bases) and lesson 07.02 (Acid-Base Reactions).
Rotting vegetation and erupting volcanoes release some chemicals that can cause acid rain, but most acid rain falls because of human activities. When humans burn fossil fuels, sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere. If large amounts of NO2 and SO2 are present in the atmosphere than the pH of rainwater will be significantly lowered. Nitric acid (HN03) can be linked to around 1/4 of the acid rain in the environment. Large amounts of NO gas is produced by high-temperature air combustion that takes place in car engines and power plants....
A huge fascination of arsenic started in the 19th century when people got word of a province in southeastern Austria where people ate arsenic. Women would eat arsenic to help gain weight and fix their complexion to look more beautiful and men would eat arsenic because they believed it helped them breath easier when they were climbing high up in the mountains. One doctor by the name of Dr. Robert Craig MacLagan, was particularly interested in this and visited the town to see for himself what was really occurring. He observed the people and tested their urine to prove that they have been indeed ingesting arsenic. He wrote about the things he witnessed in the Edinburgh Medical Journal. The men in the town would eat 6 grains/dose at least twice a week, sometimes eating it on their bread or just drinking it with their water. As a result many Victorians began self-medicating themselves with arsenic.
I have always been inspired by the workings of chemistry and mathematics. My studies of these subjects have developed my understanding and have made me pursue my interest in these two topics. I want to take up chemistry as it involves a large amount of mathematics which I value and understand to be challenging, yet very enjoyable, as there is always an alternative route to obtain the answer. Additionally, I am drawn to the course because it is a mixture of all these exacting subjects, forming a degree that is very demanding and stimulating. Chemists are constantly thinking of new ways to produce viable drugs containing different isomers to improve the pharmaceutical sector using mathematical equations. Chemistry is about innovation, applying information to new areas and how to do things better than they were before, the degree appeals to and fascinates me.
Hydrogen sulfide is a colorless gas with an obnoxious rotten egg odour. H2S is highly flammable, noxious and vitriolic in nature. Many petroleum and natural gas processing industries produces H2S as a by-product gaseous stream. Most H2S in the air comes from natural sulfur cycle. Exposure to H2S can lead to various health issues like burning/tearing of eyes, cough, and shortness of breath. Moderate concentration can lead to respiratory issues. So it is advisable to make use of this gas in other industrial operations.
The process need toluene and hydrogen as a main reactor. Then, toluene and hydrogen are converted in a reactor packed with catalyst to produce benzene and methane. This reaction is exothermic and the operating conditions are 500 0C to 660 0C, and 20 to 60 bar of pressure. This process begins with mixing fresh toluene with a stream of recycle unreacted toluene, and the mixing is achieved in a storage tank. Then, the toluene is pumped to combine it with a stream of mixed hydrogen and fresh hydrogen gas. The mixture of toluene and hydrogen is preheated before it is introduce to the heater or furnace. In the furnace, the stream is heated to 600 0C, then introduced into the reactor. Basically, the main reactions occurs in the reactor.
These are some of the many properties reasons and qualifications for us using sodium in our everyday lives. These are the reasons why sodium is used all around the world to this very day and is also why we use so much of it. Ammonia has an important role in the formation of salt crystallizations which is why it is mentioned in the above paragraph and which so will be used in the experiment that is going to take place to test the importance of ammonia in salt crystallization and to see exactly how the ammonia is going to affect the salt in the end result.
