Calcium carbonate (CaCO3) can be obtained from calcium nitrate (Ca(NO3)2) by a process called thermal decomposition. This process involves heating the calcium nitrate to a high enough temperature to cause the molecules of the compound to break apart, forming calcium carbonate and nitrogen dioxide. The reaction can be written as:
Ca(NO3)2 ? CaCO3 + 2NO2
The thermal decomposition of calcium nitrate occurs at temperatures of around 400-500 degrees Celsius. The calcium carbonate can then be collected and separated from the nitrogen dioxide gas.
The thermal decomposition of calcium nitrate is an exothermic reaction, meaning it releases energy in the form of heat, which can be used to help drive the reaction. This reaction can be used in a variety of industrial processes, such as the production of cement and lime.
In summary, calcium carbonate can be obtained from calcium nitrate by thermal decomposition, which involves heating the calcium nitrate to a high enough temperature to cause the molecules of the compound to break apart, forming calcium carbonate and nitrogen dioxide.

Well, that's a tough one! I'm not sure if it's possible to get caco3 from ca (no3) 2, but I'm sure there are some clever chemists out there who could figure it out!
