Hydrazine Essays

SPU PO3 – The Martian Nina Groenveld | VT4A Making water using hydrazine: In the movie, astronaut Mark Watney used hydrazine from the rocket fuel and separated it into nitrogen and oxygen. The formula is N2H4 → N2 + 2H2. After this he burned the hydrogen with oxygen to make water. The formula is 2H2 + O2 → 2H2O. Martian soil: Astronaut Mark Watney is able to grow crops using the water he made and Martian soil. In reality, the soil on mars does contain the right nutrients for plants to survive

In the novel The Martian by Andy Weir, the sense of time and place in which the events occur are shown in many different ways. One of these ways is when Mark finishes working with the Hydrazine. “LOG ENTRY: SOL 34. Well that took a really long time. I’ve been at it all night with the Hydrazine. But I got the job done.” (Weir 32). The sense of time is shown throughout the book with the use of Mark’s log entries. They list how many sols (days) he has been on Mars, and each day show benchmarks of his

use the machines in the Hab such as the oxygenator and the water reclaimer to take waste compounds and turn them into useful ones like water and oxygen. In addition, Mark even figured out how to make water by changing the structure of the compound hydrazine, which happens to the MAV’s rocket fuel, into water. Even though there are other chemistry concepts that Mark used to help him survive, none of them had as big of an impact on his survival as the concept of physical, chemical and nuclear changes

Luminol 5. Introduction In this experiment, luminol was prepared from 3-nitrophthalic acid and hydrazine under high heat. 3-nitrophthalic acid and hydrazine produced the precipitate 3-nitrophthalhydrazine, which was isolated using vacuum filtration. 3-nitrophthalhydrazine reacts with sodium dithionite to produce luminol. The solid luminol was isolated by vacuum filtration, then its chemiluminescence was demonstrated through its reaction with iron from a solution of potassium ferricyanide. The product

2. Experimental method 2.1 Synthesis of PbSe and PbSe: Nd nanoparticles Neodymium doped PbSe samples (Pb1-xNdxSe) with x=0, 0.05, 0.10 at pH 5 were prepared by wet chemical precipitation technique, adding hydrazine hydrate as the precipitating agent at room temperature. Freshly prepared aqueous solution and analytical grade lead nitrate (Pb(NO3)2), neodymium oxide (Nd2O3) and selenium dioxide (SeO2) were used as precursor materials. Initially, 2 g of lead nitrate and 0.555 g selenium dioxide were

The Martian is a book full of science fiction, suspense, and page-turning excitement. It also has lots of humor, and makes anyone who reads it laugh a lot. Mark Watney is trapped on Mars with a few hundred days of food and water. He also does not have any communication with Earth or his crew, and the next mission to Mars is four years away, and will take too long to get there. The theme of the story is the difficulty and isolation of being left alone. He is trapped and tries to escape. This book

about biology on Mars, he figured out how to make fertilizer, water, a suitable atmosphere for growing. To get fertilizer the most disgusting obstacle was using his own and his crewmates’ feces. In the process of making water, Watney had to use hydrazine from the

Lance Feig CH 128L Luminol Report Purpose The purpose of this experiment was to synthesize luminol and then perform a chemiluminescence reaction. First, 3-nitrophthalic acid was reacted with hydrazine to generate 3-nitrophthalhydrazide, which is a cyclic diamide. The conversion of a carboxylic acid functional group to an amide function group is reversible and produces water. To drive the reaction to the amide product, the reaction was performed at 300 ˚C to evaporate the water product, which is

2. GRAPHENE FABRICATION TECHNIQUES Fabrication of graphene can be divided into two different approaches. They are bottom-up and top-down approaches. Bottom-up methods involve synthesizing graphene from alternative carbon containing sources, whereas top-down methods involve breaking apart the stacked layers of graphite to yield graphene. Figure shows the schematic representation of the bottom-up and top-down graphene synthesis. Figure 10: A schematic of ‘bottom-up’ and ‘top-down’ graphene synthesis

describes how an object acts when no force is acting upon it. So, rockets stay still until a force is applied to move them. Most liquid chemical rockets use two separate propellants: a fuel and an oxidizer. Typical fuels include kerosene, alcohol, hydrazine and its derivatives, and liquid hydrogen. Many others have been tested and used. Oxidizers include nitric acid, nitrogen tetroxide, liquid oxygen, and liquid fluorine. Since most future missions will utilize GPS satellite

chemical structure is comprised of a cyclic diamide moiety. The synthesis of luminol began from 3-nitrophthalic acid which is a dicarboxylic acid. The first step of the synthesis was the double amination of the carboxylic acid functional groups with hydrazine to construct the cyclic diamide substructure which was 3-nitropthalhydrazide. This step required a lot of heating therefore a high boiling point solvent was used so the reagents remained in solution at the elevated temperatures of 230 degrees Celsius

"The Martian" by Andy Weir is a classic survival story about a stranded astronaut far away from society, but with a twist. The main character, Mark Watney, is stranded on Mars. The novel is set in the near future and follows the story of an astronaut who is left behind on Mars after his crew departs. One of the reasons that "The Martian" is an interesting book to read is its scientific realism. The author has conducted extensive research on the planet and the challenges that a human would face if

TABLE 1 - Particle Size Range (micrometers).5 3. RESULTS AND DISCUSSIONS Experiment A shows that the compound present in the dust sample is Sodium Nitrate. Experiment B shows the dust is inhalable and can directly get to the lungs. From the oxidation state of nitrogen, Nitrate is the most oxidized form of nitrogen present in the environment. It accounts for the majority of the total available nitrogen in surface waters (Environment

The Martian Us as teenagers may at the first look at the movie The Martian and think its science related. The Martian is about these five astronauts that go to Mars, after they are there for awhile a huge storm happened. An antenna goes through one of the members Mark and he died. At least that 's what they thought. The rest of the members leave Mars. Mark (who is a astronaut and a botanist) has to try to survive, he doesn 't know how long he 'll be on Mars or if he 'll ever get back to Earth. You

I am going to write a description from Mark Watney’s perspective who is left stranded on Mars for SOL561?. In this description, Mark is trying to overcome this dilemma by taking it step by step. The unheard side. It was a crisp Autumn night. Tracey was in deep sleep on a bed fit for two. A bed that once held the warm presence of the man who was her lover. A bedroom once shared by a man who made a lifetime oath to her ‘till death do us part’. A house that was once filled with infinite happiness

Day ESS 102 Research Paper Rough Draft #1 Propellantless Spaceflight Heavy fuel payloads have always been an unwanted stow-away on all spaceflights. Whether it’s the 4.4 million pounds of fuel for the Space Shuttle or the few hundred pounds of Hydrazine on Voyager, propellant has always been a concern. In the Sci-Fi story I’ve chosen to write, microwave propulsion in the form of the EmDrive has been perfected and expanded on. Humans have established colonies on Mars and have outposts across the

Tan November 11, 2014 November 25, 2014 Abstract 　　Aldehydes and ketones are two similar functional groups containing the carbonyl group. In this experiment, the main objectives are to be able to do qualitative tests on the samples, to be able to write the respective correct chemical reactions for each sample on each test, and to be able to differentiate aldehydes and ketones from one another

The story the Martian is an interesting story to read. It is about a man’s journey to Mars, his adventures and his struggles. His journey to Mars went from being a great opportunity to being a devastating turn of events that led to Mark Watney being stranded on Mars for approximately 550 sols(days). During the time that as spent on Mars, Mark had a lot of ups and downs which he learned from. He had a lot of problems and concerns to consider. “If the oxygenator breaks down, I’ll suffocate. If the

(That is why you were born, that is why your mother was floated that is why you were sent to the Earth and that is why Bellamy’s soulmate has a knife to his neck.) If it were any other person alive, perhaps even yourself, they would be lying in the dirt by now but not her, not the girl who has just shouted
