Background
Ammonia is one of the most abundant chemicals compounds found on Earth. Ammonia is made up of nitrogen and hydrogen ions. Due to nitrogen’s affinity for protons, ammonia is a basic compound. Ammonia was discovered by Joseph Priestley in 1774, and the exact compound was found by Claude-Louis Berthollet in 1785 (Seagrave 2018). The major method of ammonia production is called the Haber process. The Haber method involves combining nitrogen and hydrogen at high temperatures and pressures inside of a PFR reactor with a catalyst present in the reactor (Ammonia 2016). Ammonia is highly abundant because it is produced in soil and through the waste of plants and animals. Ammonia is used so often because it can be easily transformed from a liquid to a gas, and vice versa. Its chemical properties make ammonia dissolvable in water, which will form ammonia hydroxide. Ammonia is used in everyday life; some examples of this are

Catalytic hydrogenation is the addition of hydrogen to convert organo-sulfur compounds into hydrogen sulfides (Lichtarowicz 2016).
〖H_2〗_((g) )+RSH_((g) )→RH_((g) )+H_2 S_((g) )
The hydrogen sulfide produced is removed by passing the gas over zinc oxide, forming solid zinc sulfide.
H_2 S_((g) )+ZnO_((g) )→ZnS_((s) )+H_2 O_((g) )
The hydrogen that is fed into the reactor is produced by methane reformation.

Carbon monoxide is then used to convert water, through a water gas shift reaction, into more hydrogen and carbon dioxide (Lichtarowicz 2016). Using adsorption, the carbon dioxide is then removed. The hydrogen stream is scrubbed of all traces of carbon monoxide and carbon monoxide using a process known as catalytic methanation.

This process uses gases from the industrial exhaust which is let out into the atmosphere, which in turn makes profits out of pollution (NAIR & (IN), 2012).

The major sites for the production of ammonia are the intestines, liver, and kidneys. It is biosynthesized through normal amino acid metabolism. The kidneys generate ammonia from glutamine by the actions of renal glutaminase and glutamate dehydrogenase. Ammonia is formed from urea by the action of bacterial urease in the lumen of the intestine, which is absorbed from the intestine by the portal vein. Amines obtained from diet and monoamines that serve as neurotransmitters or hormones can create ammonia by action of amine oxidase. In purine and pyrimidine catabolism, amino groups attached to the rings are released as ammonia.
In conclusion, hydrogen is one of the many important elements on the periodic table. Hydrogen makes up 2/3 of water, 1/4 of the air, 0.15% of the earth's crust, metal hydrides found in some batteries, and in many carbohydrates we eat. Hydrogen serves as many sources of fuel, such as fuel for most starts to produce energy or for rockets. Due to how useful this element is, hydrogen has received a lot of acknowledgement throughout history.
4.Exhaust: After the Air/Fuel mix has been burnt the remaining chemicals in the cylinder (water and CO2 for the most part) must be removed so that fresh air can be brought in. As the piston goes back up after combustion the exhaust valve opens allowing the exhaust gasses to be released.
The ammonia, nitrite, and nitrate tests are used to determine if the fish’s environment is safe to live in or if the water is too toxic. Ammonia and nitrite are very toxic while nitrate is mostly harmless. To eliminate these chemicals, adding more bacterial supplement will cause the cycle to continue at a faster rate. These tests also show how the nitrogen cycle is progressing in the tank. As the cycle progresses, ammonia will decrease while nitrite increases. Then nitrite decreases and nitrate increases. Then nitrate decreases and your tank should be balanced.
Hydrogen forms lots of important bonds, primarily with the elements fluorine, oxygen, nitrogen, and carbon. A hydrogen acceptor is an element that accepts hydrogen atoms and is attracted to them. The most common compounds formed by hydrogen are hydrochloric acid, phosphoric acid, and water. Hydrogen bonds are also significant in the construction of synthetic materials, such as nylon, and organic materials like wood and cotton. Hydrogen also bonds with oxygen to form hydrogen peroxide (H2O2), which is a very common household oxidizer. Hydrogen peroxide is used to give white laundry a bleach-free bleaching. Mix it with backing soda for a painful toothpaste substitute. Remove wine, blood, tea, and coffee stains from most fabrics. Make a solution with water and scrub your sink! Water your plants with a peroxide solution to make them perky!
In able to produce ammonia, nitrogen and hydrogen gas mixture composed together under high temperature, high pressure conditions and the role of catalyst. In the spirit of perseverance, through continuous experiments and calculations, Haber finally achieved encouraging results in 1909. When the temperature is 600 degree Celsius, under the conditions of 200 atmospheric pressure and osmium catalyst, the yield was approximately 8% of ammonia. 8% conversion rate is not considered high; it will obviously affect economic production. Haber known ammonia production cannot attain high conversion rate like sulfuric acid. Haber cons...
Release of Gas was seen in (B1, B2, B3, B4, A6) as bubbling occurred due to the reaction of Copper chloride with: Aluminum shot, Aluminum foil, Zinc, Ammonium hydroxide, and Silver nitrate.
In nature hydrogen is always found combined with other elements, which means it has to be manually made by passing an electric current through water to form hydrogen and oxygen. There is a tremendous amount of energy involved in splitting the molecules to free the hydrogen from its captor. The current method of producing hydrogen from water is through the use of oil and coal. Oil and coal are the two main resources the world is trying to cut back on. The main purpose of using hydrogen is lost when considering the actual manufacturing process of hydrogen contributes a significant amount of carbon dioxide. When the big coal and oil companies start investing their profits in hydrogen, something has gone awry. Each company sees its future limited and wants to ensure their survival. Since they have the most money they will be the main producer of hydrogen. The hydrogen economy will benefit the mining and oil industry at the cost of the clean-energy dream.
Investigating the rate of diffusion of ammonia. Investigating the rate of diffusion of hydrochloric acid in agar. Planning You can change different things you do to an experiment like the amount of acid, temperature, size of the agar or concentration of the acid. It is a We can measure/observe on how long it takes to diffuse or the amount.
Carbon Monoxide is a colourless and inodorous toxic gas produced through the incomplete combustion of different carbon-based fuels, such as in products and apparatuses motorised by internal combustion engines (Carbon Monoxide Questions and Answers, n.d.), that have failed to convert carbon or carbon-based fuels into carbon dioxide (Encyclopædia Britannica, 2014). CO production can also occur naturally when volcanoes erupt, releasing the poisonous gas into the atmosphere. CO is used as an aid to engineer organic and inorganic chemical products (Encyclopædia Britannica, 2014), in fuel gas mixtures for heating in metal production, pharmaceutical and chemical manufacturing, to reduce ores and make metal carbonyls, and to fabricate and renew catalysts. “High purity CO is also used for electronic and semiconductor applications” (The Linde Group, 2013). Figure 1 shows the general equation for the incomplete combustion of hydrocarbons to produce carbon monoxide.
Another system is called the spray dry system. A slurry of alkali is njected into the flue gases. The heat in the flue gases causes water to evaporate. The sulfur dioxide reacts with the drying alkali solution to form a solidi reaction product. There is no waste water from this process.
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.
