The problem with this latter system is that traditional fuels and oxidizers are expensive and dangerous to store. To cut down on both cost and risk, SpaceShipOne is propelled by a mixture of hydroxy-terminated polybutadiene (tire rubber) and nitrous oxide (laughing gas). The rubber acts as ...
Unlike its main speed competition, the rocket, which burns fuel using onboard oxidizers like ammonium nitrate, potassium chlorate or ammonium chlorate, ramjets breathe air. Thus, while rockets can operate in the near vacuum of space, ramjets must fly through the atmosphere. They must do so at...

(and how not to) store and handle them. While you likely won’t find out the specifics on exactly how to dispose of something right on the packaging, you will learn particulars about safe disposal, such as materials a certain substance cannot come into contact with and other ways to ...
Magnesium requires a coating to prevent it from prematurely reacting with the oxidizer in the comp. Additionally, sometimes barium nitrate or other oxidizers are used instead of ammonium perchlorate. In 1987, John "Skip" Meinhart offered some details about his noteworthy strobing star formulas in ...
With liquid propellants, there are three main types: petroleum-based, cryogenic and hypergolic. All three of these propulsion methods store their oxidizers and fuels separately until thrust is needed. When rockets fueled with a liquid propellant are fired, a bit of each (fuel and oxidizer) is ...
Heart conduction is impaired resulting in arrhythmias, extrasystoles, ventricular fibrillation and other changes which lead to asystole and cardiac arrest.Share Tweet Email Follow Answer Previous: Why is it bad to mix mineral spirits and oxidizers? Next: In chemistry what is the function of boron...
some members of the microbial community have specialized in using variousnitrogen compoundsas energy source for optimal growth. This is especially the case amongst anaerobicammoniumoxidizers: These bacteria do not require oxygen for their metabolism but instead, convert two important nitrogen compounds, am...
If you drink a lot of coffee, like I do, then you’ll need to clean your coffee maker once in a while. Yes, coffeemakers need cleaning just like anything else. If you search the internet, or go to the store, there are commercial kits that you can buy specifically for certain brands...
