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).
The lightning and thunder sound occur at the same time, but an observer will experience a delay in hearing the thunder depending on the distance from the lightning strike.  â¦  Light travels at slightly less than 3.00 x 106 kilometres/second or around 1.88 x 106 miles/second. That is fast.
