How many moles of CaCI2 will be formed if you react 1 mole HCI? How many moles of CaCI2 will form if you react 5.5 moles of CaCO3?
2 HCI+CaCO3->CaCI2+H2O+CO2


    Look at the your other posts for explanations.

    1 mol of HCl*(CaCl2/2 mol of HCl)= 0.5 mol of CaCl2

    5.5 mol of CaCO3*(1 mol of CaCl2/1 mol of CaCO3)= 5.5 mol of CaCO3
