You carefully measure 14.00g of CaCO3 powder and add it to 56.70g of HCl solution in a reaction flask of known mass. You notice bubbles as a reaction takes place. You then determine that the contents of the flask have a mass of 64.96g . The relevant equation is CaCO3 (s) + 2HCl (aq) --> H20 (l) + CO2 (g) + CaCl2 (aq) Assuming no other reactions
