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).
It can strike as far as 5 or 10 miles (8 or 16 kilometers) from the storm, in areas that most people do not consider to be a lightning-risk area. &#149 During a thunderstorm, each flash of cloud-to-ground lightning is a potential killer.t can strike as far as 5 or 10 miles (8 or 16 kilometers) from the storm, in areas that most people do not consider to be a lightning-risk area. &#149 During a thunderstorm, each flash of cloud-to-ground lightning is a potential killer.
