Oy vey (Yiddish: ××± ×°×² â) or oy vey ist mir is a Yiddish phrase expressing dismay or exasperation. Also spelled oy vay, oy veh, or oi vey, and often abbreviated to oy, the expression may be translated as, oh, woe! or woe is me!.Its Hebrew equivalent is oy vavoy.he Latin equivalent is heu, vae! (pronounced, hoi, vai, amongst others); a more standard expression would be o, me miserum, or heu, me miserum. According to Chabad.org, an alternative theory for the origin of the Yiddish expression is that oy stems from Biblical Hebrew, and that vey is its Aramaic equivalent.
Chemical Reactions Used to Generate the Gas Inside the airbag is a gas generator containing a mixture of NaN 3, KNO 3, and SiO 2. When the car undergoes a head-on collision, a series of three chemical reactions occur inside the gas generator.
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.
