The Chemistry Behind Airbags Hannah Klein 4/5/13 pd. 11 Airbags are a type of automobile safety restraint like seatbelts‚ they are balloon-like devices that expand when a car experiences a collision‚ providing a cushion of air that prevents a person from bashing their face on the dashboard or steering wheel and suffering concussion‚ disfigurement‚ or worse. Airbags are usually fitted in the front seats. A car that is described as having a “driver’s side airbag” has one airbag only‚ designed

intensity and frequency has when photons are bounced against sodium metal. The analysis is expected to show that electrons will dislodge from the metal when photons hit it‚ adjusting the intensity and light frequency will affect the quantity of electrons dislodging from the sodium metal. A number of questions were answered backing up the analysis which shows that increasing the intensity will cause more and more electrons to dislodge from the sodium metal. And longer frequencies of light tend to increase

Standardize a solution of potassium manganate(VII) by an iron (II) salt (ammonium iron (II) sulphate) Introduction Oxidation numbers describe the number of electrons the atom will gain or lose during a reaction. Each atom in an equation can be assigned an oxidation number according to certain rules. If the oxidation number of an atom increases as you go from the left side to the right side if an equation‚ oxidation has occurred (electrons have been lost); if the oxidation number decreases

Solutions Solutions are a combination of solvents and solutes. When a solute dissolves into a solvent‚ the combined product of the two reactants is called a solution. The definition of a solute is the reactant that’s being dissolved. The only difference from a solute and a solvent is that the solvent is the one that’s doing the dissolving. Molecules randomly flow in all directions until there is an equal concentration throughout the solution. The dissolving process can vary depending
