lots of carbon dioxide and warm temperatures
Na2CO3 + Ca
There is no compound CaCO. Since carbon and oxygen are non-metals, the only compounds they are likely to form with calcium are ionic compounds. So that would require making an anion out of carbon and oxygen. The only polyatomic anion that you can get from carbon and oxygen is carbonate, CO32-. So the calcium carbon oxygen that you might be referring to is calcium carbonate, CaCO3.
Na(3)Co(2)+Ca
NaNO3+CaCl2->NaCl+Ca(NO3)2
Limestone as it is formed of calcium carbonate which reacts with acid to form (amongst other things) carbon dioxide.
It's most likely that the calcium carbonate in chalk is actually gypsum.
If CaCO3 (calcium carbonate) were to decompose, it would likely result in CaO (calcium oxide) and CO2 (carbon dioxide).
no reaction
My guess is that it would not "fizz" at all.The Fizz that one often sees when mixing calcium carbonate, sodium bicarbonate, etc with an acid is the releasing carbon dioxide CO2 from the Carbonate ion CO32-.Calcium Chloride is a salt. It will likely dissociate in the solution, but I doubt it will "fizz".If you mix Hydrochloric Acid with Calcium Carbonate you get:2HCl + CaCO3 --> CaCl2 + H2CO3 --> CaCl2 + H2O + CO2Where the Calcium Chloride is more likely kept in solution as Ca2+ + 2Cl-

Is it Calcium carbonate which neutralizes the acid.

All elements other than carbon are likely to form inorganic compounds, and even carbon is at least sometimes found in inorganic compounds such as calcium carbonate.
Calcium hydroxide can be dissolved to create a saturated aqueous solution, which is sometimes referred to as limewater. When carbon dioxide is bubbled through the limewater, the carbon dioxide reacts with water to form carbonic acid. The carbonic acid is first deprotonated to form a bicarbonate anion, which is then deprotonated once more to form the carbonate anion. The carbonate anion then reacts with a calcium cation to form calcium carbonate (the compound in limestone). Calcium carbonate is insoluble in water, and thus precipitates out. The formerly clear limewater solution has thus become cloudy, giving an indication that carbon dioxide is likely present. Reaction scheme is given below: CO2(g) + H2O --> H2CO3 H2CO3 + OH- --> HCO3-+ H2O HCO3- + OH- --> CO32- H2O CO32- + Ca2+ --> CaCO3(S) Note that if too much carbon dioxide is added or too little calcium hydroxide is used, then calcium bicarbonate will form instead of calcium carbonate. Calcium bicarbonate is water soluble, and thus will appear to produce a negative test.
