Job Description for Clinical Informatics Specialist. The clinical information specialist position works in a medical facility with a significant number of medical records to manage. They build user interfaces and teach the clinical staff to use them properly.
Air bags are not inflated from some compressed gas source but rather from the products of a chemical reaction. The chemical at the heart of the air bag reaction is called sodium azide, or NaN. Image: NEW CAR ASSESSMENT PROGRAM, CRASH TEST AREA. CRASHES trip sensors in cars that send an electric signal to an ignitor.lthough we don't usually associate automobiles with chemistry, a lot of chemistry takes place in a working car--the burning of gasoline to run the engine, for example, and chemical reactions in the battery to generate electricity.
A typical airbag contains 50.0 g of sodium azide, NaN3. Upon impact, the airbag deploys and inflates within 40 milliseconds to a volume of about 60 L, at a velocity between 150 and 250 mph.The airbag inflates due to the decomposition reaction of NaN3 and fills with nitrogen gas in the following reaction:odium azide (NaN3) can decompose at 300oC to produce sodium metal (Na) and nitrogen gas (N2). The signal from the deceleration sensor ignites the gas-generator mixture by an electrical impulse, creating the high-temperature condition necessary for NaN3 to decompose.
