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.
What prompts an air bag to inflate by way of this reaction? There are sensors in the front of the automobile that detect a collision. These sensors send an electric signal to the canister that contains the sodium azide and the electric signal detonates a small amount of an igniter compound.ir 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.
