The hydratation of concentrated OH- and Na+ ions (by dilution) is exothermic, it gives an energetically prefered state of matter.
(Hydratation is the extra surrounding of the ions by polar water molecules of the solvent).
It's exothermic. Heat will be created (liberated) when the calcium reacts with water to form the hydroxide and hydrogen gas.
This chemical reaction is endothermic.

Plants are endothermic because they use photosynthesis as their means of obtaining energy and endothermic means energy obtaining. A candle flame would be considered exothermic because it releases heat.
No. Slaked lime is Ca(OH)2 and quicklime is CaO. Limestone is CaCO3 . CaSO4 when hydrated would be gypsum. It is not lime.
Slaked lime is much more alkaline and effective at reducing acidity quickly - it is Ca(OH)2 whereas powdered limestone is CaCO3 and not as alkaline/basic. CO2 is also given off when the limestone reacts with the acid. Water is given of when slaked lime reacts. Mathematically it takes 100 g of limestone to 73g of HCl (as an example) where it would take only 74g of slaked lime per 73g HCl.
This is the cycle which tyrns lime stone to - quiclime form this to -Slaked lime from this to - lime water an this turns into limestone and a cycle is created.

limestone
quick lime is CaO and limestone is CaCO3 and the method to prepare limestone out of quick lime is just heat the limestone. CaCO3--------CaO + CO2 HEAT
Limestone is called limestone because it has lime in it from the sea water it if formed in.
Yes, slaked lime is manufactured from limestone: CaO + H2O = Ca(OH)2
