Question

Limestone powder disappears on adding to dilute hydrochloric acids

Answer 1

Hey mate here's your answer :-

Chemically limestone is Calcium carbonate (CaCO3).
So,When it reacts with HCl it forms 
Calcium chloride and Hydrogen Carbonate.
CaCO3+HCl=CaCl2+H2CO3
 is a very unstable compound and it readily breaks into Carbon dioxide and Water.
Again,
CaCO3+HCl=CaCl2+CO2+H2O


I hope it helps .
