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).
For most thunderstorms, 70-90% of lightning strikes are intracloud or from cloud to cloud. From 10-30% of lightning can be cloud to ground (CG), depending on the storm. Lightning strikes the earth more than 100 times each second and 8 million times per day.
