Today, we discussed the answers to the Data - Based Questions.  *Note: The labelling of the graph is incorrect. 'Yield of Ammonia' is switched with 'Pressure'. In simple words, 'Yield of Ammonia' will be on the y-axis, and 'Pressure' on the x-axis. Here are the answers to the questions: 1) The temperature 200 degree Celsius achieves the highest yield of ammonia. 2) As the pressure increases, the yield of ammonia increases as well. 3) The reasons are that: expensive to maintain more cost effective to produce lesser yield at faster rate 4) As the pressure increases, the amount of ammonia will increase However, it is expensive to build and operate a plant that can withstand such high pressures. So, a compressed pressure is used of 200atm. 5) If pressure is increased, then system will shift to the side with fewer moles of gas. So if pressure is increased, then system will shift to the right side, that is the product side. And since, it is shifting right, for...

The Haber process, also called the Haber–Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. The German chemists Fritz Haber and Carl Bosch developed it in the first decade of the 20th century.  Hydrogen + Nitrogen <---> Ammonia Hydrogen is obtained from Methane and steam, producing Carbon monoxide and Carbon dioxide as a biproduct CH₄ + H20 (g) = H2 + CO + CO2 The hydrogen and Nitrogen from the atmosphere are then compressed and then delivered to the reactor, where Ammonia is produced. The gases are cooled down, and the ammonia is available as a liquid. Unused Nitrogen and hydrogen are recycled back into the reactor The forward reaction is favored, and is exothermic The Haber process also follows Le Chatelier's principle, keeping operating and production costs in mind while maximizing ammonia production. Similarly, the compromise pressure is kept at 200 ATM, and the temperature is kept at 400-450...

Balancing chemical equations is one of the important topic in chemistry. An equation is balanced when the same number of each element is represented on the reactant and product sides. Equations must be balanced to accurately reflect the law of conservation of matter. With that said, lets see how to balance chemical equations. Lets take this equation: N2 + H2 ------------> NH3 First make a column and write the elements with the number. Like this: Reactants:                                       Products:  N - 2                                                N - 1 H - 2                                                 H - 3 From  this we ...

  The nitrogen cycle The nitrogen cycle is one of the many biogeochemical cycles that takes place on Earth. In this process, atmospheric nitrogen is cycled through soil, animals and plants with the help of bacteria. Let us take a look at this process. Nitrogen is present in the atmosphere as N2. There are some plants which need nitrogen to grow, the primary example being leguminous plants. But the nitrogen doesn't directly enter these plants. Leguminous plant roots have these small holes called root nodules, which house the Rhizobium bacteria. This bacteria converts the atmospheric nitrogen into ammonia (NH3). Now, this ammonia is passed on to the Nitrifying bacteria, which are present in the soil. They convert the ammonia into nitrites (NO-2) and the nitrates (NO-3). This process is called nitrogen fixation, where atmospheric nitrogen is converted to nitrates. This process can also occur by lightning strikes. The roots of the plant absorb these nitrates. Now, there is another part...

The monolake is a saline soda lake in the united states of America, California to be more specific. it is a very interesting lake because of its salinity, and the amount and type, or organisms living inside of it. lets learn a bit more about it. starting off with one of the questions you must have had from the beginning what special salts made this lake so salty. This lake has a very unique chemical composition, which in turn makes it alkaline, the salts in this lake are combinations of chlorides, carbonates, and sulfates. It also consists of large amounts of borate and potassium. this also intern increases the pH of this lake, the pH of monolake is a whooping 10, almost thrice of a normal river or lake. so how can organisms live their life's in this lake? There are many types of flora and fauna that appear in the mono lake at different times of the year, many of which are birds, the osprey, many types of songbirds, and phalaropes come at many different times of the year, but that’...
