Why is calcium oxide called quick lime?
Calcium Oxide reacts with CO2 in the air to convert back into limestone. It also reacts violently with water. It will also blind you quickly. Probably one of these.
What is the colour of the precipitate formed when a calcium salt reacts with sodium hydroxide solution?
A white hydroxide: Ca(OH)2.
Can calcium be used in electric wires?
No, it is not ductile enough for use in wires and reacts rapidly with air and moisture, which would quickly ruin any product made of calcium.
What is the substance in limestone that reacts with acid?
Limestone is basically Calcium Carbonate(CaCO3). The metal part(Calcium) is the reactive part in it. It reacts with acids as well as bases. For example, it reacts with Hydrochloric acid to form calcium chloride whereas reacts with Ammonium hydroxide to form Calcium Hydroxide.
What is the product formed when calcium chloride reacts with nitric acid?
Any reaction; the solution contain ions: Ca2+ , Cl- , H+ , NO-3.
What effects how quickly acid rain reacts with calcium carbonate?
It is cus of the lower
What happens when you mix Calcium Chloride with Copper Sulfate?
the copper sulfate reacts and changes colour
What affects how quickly acids react with calcium carbonate?
It's the concentration of the acid.Limestone and marble are forms of calcium carbonate.Acid rain reacts with calcium carbonate. The stronger the acid the more quickly it effects calcium carbonate and dissolves.

Which one of iron copper zinc or calcium reacts quickly with diluted hydrochloric acid?
Among these calcium is highly reactive towards acids.
Does calcium tarnish?
Yes. Calcium is very reactive and tarnishes in minutes, if not seconds and if left out will corrode away. It will reacts vigorously with water and will quickly be consumed.
What is the colour of the precipitate formed when a calcium salt reacts with sodium hydroxide solution?
A white hydroxide: Ca(OH)2.
What forms when calcium reacts with fluorine?
Calcium reacts with fluorine to form calcium fluoride (the symbol is CaF2).
