i'm really sorry but i meant examples which cause an reaction big enough to move a small toy car. sorry! my bad.

Reactions between acids and carbonates occur as per acid-base chemistry of carbonates:
The carbonate ion is a weak base when put into an aqueous solution. This is because it is a conjugate base of a weak acid. As such the carbonate ion seeks to reclaim hydrogen atoms.
CO3,2- + 2 H2O <> HCO31- + OH1- + H2O <> H2CO3 + 2 OH1-
The kb value for carbonate ion and its conjugates is as follows.
CO3,2- + H2O <> HCO31- + OH1- kb = 2.1 * 10-4
HCO3,1- + H2O <> H2CO3 + OH1- kb = 2.4 * 10-8
on reaction with acid generally carbonates produce CO2;
Na2CO3 +2HCl = 2NaCl+CO2 +H2O;
Na2CO3 + H2SO4 = Na2SO4+CO2 +H2O;
Similar reactions take place with other acids.

How about
CaCO3 + 2HCl ----> CaCl2 + CO2 + H2O
The list is endless.
