2HCl (aq)+CaCO3 (s)->H20(l)+CaCl2(aq)+CO2(g). If using 40cm^3 of 2.5mol.dm^-3 Hcl and 5.67g of CaCO3, determine the limiting reagent and how much CO2(g) could be theoretically produced by this reaction.

First, we have to convert the starting measurements for the HCl and CaCO3 content into moles so we can compare the ratios to the formula. 40cm^3=0.04dm^30.04dm^3 2.5mol.dm^-3=0.1 moles of HClmass/molar mass=...
