The gas carbon dioxide is released.

Limescale is mostly calcium carbonate with some magnesium carbonate mixed in there as well. So the answer would be calcium.
its a philosophical conundrum
you would get calcium nitric and water. trust me people my dad's a scientist
If CaCO3 (calcium carbonate) were to decompose, it would likely result in CaO (calcium oxide) and CO2 (carbon dioxide).
Calcium hydroxide and nitric acid yield calcium nitrate and water. Ca(OH)2 + 2HNO3 --> Ca(NO3)2 + 2H2O
calcium carbonate+ nitric acid. a strong acid would replace a weaker acid in most ionic compounds, so you would produce calcium nitrate and carbon dioxide. well, being that nitric acid is widely UNAVAILABLE to most people, it is easy to find potassium or sodium nitrate. if you are going specifically for calcium nitrate you can double displace calcium carbonate with potassium or sodium nitrate resulting in potassium or sodium carbonate and (aq) calcium nitrate. the potassium or sodium carbonate will probably precipitate out much quicker than the nitrate depending on how exact your equation for displacement is. and you should be left with (aq) calcium nitrate. boil off the water and preferably recrystallize for purity. if youre using calcium carbonate just to get any form of nitrate, i recommend simply buying potassium nitrate. if it is not assessable in your area and are trying to get an oxidizer ( i assume thats why you are trying to make a nitrate) i recommend going with a chlorate or perchlorate, these are easier to make at home through electrolysis.
By distillation or evaporation of water
Calcium Carbonate (CaCO3) obviously is different than Calcium Chloride (CaCl2) as they contain different elements. Carbon and oxygen (carbonate CO3) in Calcium Carbonate. Chlorine (Cl) in Calcium Chloride. Technically, they would both be good calcium supplements.
If it contain magnesium but no calcium then it would be magnesite.
calcium carbonate
The precipitate would be calcium carbonate, CaCO3.
