The Haber-Bosch Process

-
Fritz Haber was a German physical chemist who won the Nobel Prize in 1918 for creating a method of forming ammonia. Ammonia is a substance made of Nitrogen and Hydrogen. Carl Bosch was a chemist who took the process made by Fritz Haber, and turned it into a large scale experiment by adding high-pressure to the process. This experiment got an award for being the first industrial chemical process to use high pressure.

The process of making ammonia, created by Fritz Haber, if fairly simple, and doesn't require too many tools or elements. It starts by directly combining Nitrogen from the air with hydrogen under very high-pressures, and fairly high temperatures. The catalyst used is made of iron. The use of an iron catalyst ensures that the process can be carried out at low temperatures. 

Low temperatures are advised, because the lower the temperature during the process, the higher amount of ammonia gained from the process. The recommended temperature for this commercial process is 400*C to 650*C (750*F - 1200*F), with recommended pressure of 200 - 400. This process is the most economical process having to deal with nitrogen.

In the future, this process can be used for many new topics and to fix many problems. Since the process was perfected in 1913, it has been used for many things. For example, the ammonia from the Haber-Bosch process is used for fertilizer on farms. This fertilizer is used to help grow about 40% of the world's food.

Force and Motion in Concerts

Force and Motion Blog  By Amadi Clemens INTRODUCTION: Do you listen to Travis Scott? If so, you know of his most recent album AstroWorld has been on tour. One of his recent shows (in Oakland, California) he performed with a roller coaster. Crazy, right? It wasn’t like a full roller coaster that you see Six Flags. It’s like the Ring of Fire at Clementon Park. His ring ties into his theme park theme! PROS AND CONS: There are pros and cons that follow this event. A pro is that it was a fresh idea. I’ve seen amusement parks and rides in music videos but never live in concert. Another pro is that it was eye-catching and entertaining.. The main idea of a concert is that it is entertaining, this is going back to the idea of fresh. A con is that it’s very dangerous. Although thrilling, what if something goes wrong? What if it breaks? What if it stops mid-way in the year and he can’t rap anymore? Mechanical service would have to come and get him and that can ruin the concert. Another con, ...

Chemical complexities that causes Saturn's rings to change planet’s atmosphere

Ayad Alhazmi 10/19/2018 Chemical complexities that causes Saturn's rings to change planet’s atmosphere New discoveries are made today on Saturn's rings by the Cassini space probe. Based on data from the final orbits of NASA's Cassini space probe shows the rings of Saturn. Some of the most amazing celestial objects in the universe are far more chemically complicated than was previously understood by scientist. When the Cassini space probe first gathered the information from 2017 and the signals of Cassini took scientist a long time to retrieve the information. Also knowing the astrophysicists are still studying it is beyond my reach. I will show you a quote by a professor of physics and astronomy Thomas Cravens. "Two things surprised me. One is the chemical complexity of what was coming off the rings -- we thought it would be almost entirely water based on what we saw in the past. The second thing is the sheer quantity of it -- a lot more than we originally expected. ...

The Earth is a very big Magnet Its North and South Poles are Highly Magnetic

The Earth is a very big Magnet     Its North and South Poles are Highly Magnetic   By: Alzahraa Alrubaiey Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Earth has two geographic poles: the North Pole and the South Pole. They are the places on Earth's surface that Earth's imaginary spin axis passes through. Our planet also has two magnetic poles: the North Magnetic Pole and the South Magnetic Pole. The magnetic poles are near, but not quite in the same place as the geographic poles.   The Earth is a magnet that can interact with other magnets in this way, so the north end of a compass magnet is drawn to align with the Earth's magnetic field. Because the Earth's magnetic North Pole attracts the north ends of other magnets, it is technically the South Pole of our planet's magnetic field. A compass point north because all magnets have two poles, a north pole...
