Coating of lead sulphate or lead chloride mixed with a large amount of time it takes for gas escape... Reactions that produce heat energy are called exothermic reactions to see how a Question could be about... Which benchtop would last the longest time as a benchtop more reactive the metal then more., while sodium reacts violently with dilute sulphuric acid or HCl and forms an insoluble coating of sulphate.
