A balanced chemical equation for the reaction is;

"CaCO_3+2HCl\\to CaCl+CO_2+H_2O" .The mole ratio of "CaCO_3" and "CaCl"

"{1mol CaCO_3}\\over1molCaCl_2" and "1mol CaCl_2\\over1molCaCO_3"

Mole ratio of "HCl" and "CO_2"

"2mol HCl\\over 1mol CO_2" and "1molCO_2\\over 2HCl"

Mole ratio of "CaCO_3" and "HCl"

"1molCaCO_3\\over 1mol HCl" and "2mol HCl\\over 1mol CaCO_3"

Moles of each reactant "=" The given molar masses

"30.0gCaCO_3" "*" "1molCaCO_3\\over100.1g CaCO_3"

"=0.30molCaCO_3"

"20.0gHCl" "*" "1mol HCl\\over 36.5gHCl"

"=0.548molHCl"

The mass of "CO_2"

"0.30mol CaCO_3" "*" "1mol CO_2\\over 1mol CaCO_3" "*" "44.01gCO_2\\over 1mol CO_2"

"=13.203g CO_2"

Mass of "HCl"

"0.548mol HCl" "*" "1mol CaCO3\\over 2mol HCl" "*" "100.1g CaCO_3\\over 1mol CaCO_3" "=27.4g CaCO_3"

Mass of "CO_2" "= 27.4g-13.204g"

"=14.197gCO_2"
