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).
First off, itâs impossible to have lightning without thunder and itâs impossible to have thunder without lightning. Heat lightning is nothing more than seeing lightning and not hearing the thunder, because the storm is too far away. Lightning is pretty darn bright and can be seen for tens of miles. Thunder is a compression wave and will dissipate with time and distance. Under excellent conditions, thunder can be heard about 12 miles away from the lightning strike. However most of the time conditions arenât this good and we usually canât hear thunder any more than about 5 miles away.
