Alkyl Halide Reactions. The functional group of alkyl halides is a carbon-halogen bond, the common halogens being fluorine, chlorine, bromine and iodine. With the exception of iodine, these halogens have electronegativities significantly greater than carbon.
Its been said that most car companies make it so where airbags deploy based on the impact. It is said that the airbag will not deploy until the impact generates 7 G's of force. For most vehicles that speed is equivalent to hitting an object at 12 mph or hitting another vehicle at 25 to 30 mph. It is dependent upon the impact of the crash.

The default speed limit from the factory is 12.4 MPH (20.0 KPH). In certain settings, for example a sports teamâs training center, the treadmill can be set to its full speed of 15.6 MPH (25.1 KPH). In other facilities, such as a Physical Rehabilitation Center, a lower setting may be appropriate. Likewise, the elevation limit can be set anywhere from 0% to 15% grade.
