Not only acids and bases dissociate, water dissociates too: and the equilibrium of this reaction is described by the equation. 1.7. However, in practice we use simplified version of this equation, called water ionization constant (sometimes called also water ion product) 1.4.
A lightning flash preceding its thunder by one second would be approximately 350 metres (0.22 mi) in distance; a delay of three seconds would indicate a distance of about one kilometer (0.62 mi) (3Ã340 m). A flash preceding thunder by five seconds would indicate a distance of approximately one mile (1.6 km) (5Ã340 m).
NEXT PAGENEXT. It is possible to figure out how far away a lightning strike is with some simple mathÂ­. Sound travels through air at the speed of sound.. Officially, the speed of sound is 331.3 meters per second (1,087 feet per second) in dry air at 0 degrees Celsius (32 degrees Fahrenheit).
