how are airbags and stoichiometry related?

whew, thats odd, um i would have to say the reaction that takes place to create all that gas that is produced to fill up the air bag, im completely guessing tho, so dont take my word on it

For example, the explosive inflation of automotive airbags is the result of the sudden decomposing of a compound called sodium azide (NaN3) to release nitrogen gas.

tire pressure, air pressure in a scuba tank, pressure in your grill's butane tank, atmospheric pressure, when piloting an airplane, so you can determine your true altitude, pressure of the CO2 in your fire extinguisher.

many\n\nsome are equations involving the mass and momentum of the vehicles and how fast and destructive and forceful a vehicle was when it hit another car or object.   \n\nother equations involve friction calculations.  so the cops can figure out how fast you were going based on how long the skidmarks were that you left.\n\nother equations are similar in that they may just figure out your speed from the trajectory of your vehicle, or say, how fast did they hit that bump in order to cause the car to hit 8 feet up in the tree.

stoichiometry is easy, there are many websites that can tell you exactly what do to for different types of problems\nhttp://www.chemtutor.com/\nhere is the specific website for help on mols and stoichiometry\nhope that helps!\nhttp://www.chemtutor.com/mols.htm

Here you go ...\n\na)  The idea of buoyancy was summed up by Archimedes, a Greek mathematician, in what is known as Archimedes Principle: Any object, wholly or partly immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object. \n\nb)  DENSITY is a physical property of matter, as each element and compound has a unique density associated with it. Density defined in a qualitative manner as the measure of the relative "heaviness" of objects with a constant volume.\n\nFor example: A rock is obviously more dense than a crumpled piece of paper of the same size. \nA styrofoam cup is less dense than a ceramic cup.\n\nDensity may also refer to how closely "packed" or "crowded" the material appears to be - again refer to the styrofoam vs. ceramic cup. \n\nc)  Low pressure areas have less atmospheric mass above their location, whereas high pressure areas have more atmospheric mass above their location. Similarly, as elevation increases there is less overlying atmospheric mass, so that pressure decreases with increasing elevation.  As elevation increases, the number of molecules decreases and the weight of air therefore is less, meaning a decrease in air pressure. In fact, while the atmosphere extends more than 15 miles (24 km).\n\nI hope this helps.

The previous responder brings up excellent points, particularly about the method relying on how good the analyst is.  This is highly true!   However I would add, that gravimetric methods are typically more ACCURATE for the following reasons:\n\n1.  Errors associated with volume measurement (loss in transfer, parallax, spillage, over-titration, etc.) are reduced in gravimetric measurements.  In most gravimetric measurements, you WEIGH a final product, which either IS the compound of interest, or is stoichiometrically related to it.\n\n2.  Gravimetric methods are less sensitive to temperature than volumetric methods.\n\n3.  While BOTH types of methods are subject to sample loss, gravimetic methods are less so.  (Note:  This is less true if the analyst is a clutz.   Goes very well with the previous poster's comment!)\n\n4.  A mass is easier to reproducibly determine than a concentration.   (Any day of the week!)\n\n5.  A mass is easier to STANDARDIZE than a concentration.  Again there are errors associated with both, we concede, but mass is generally easier to deal with.  \n\n6.  You will more likely encounter limits (of sensitivity) in volume measurements than you will in  mass measurements, depending on how your lab is equipped.  \n\nThese are a few thoughts, I'm sure there are others.

Here's one: Measure the density of air.\n\nTake a flask, weigh it.\nVacuum out all the air, then weight it again.

It's the ratio of the volume taken up by air spaces (the voids) to the total volume of a material.

Not a good question. Power is related to the volume of fuel/air mixture.

that depends on the material's specific gravity\nweight in kg = specific gravity * volume in ltrs

You can create an analogy between a cell and a car\nNucleus = engine (controls the functioning of the car)\nmitochondria = alternator (produces energy when engine running)\ncell vacuoles = radiator (retention of water)\ncell wall = car frame (keeps the shape and rigidity)\nflagella = car tires ( cell movement )\n\ncontinue finding similar functions or functions that u can connect between the two.\n\ngood luck!
