1. The main component of egg shells is CaCO3, If 25.0 cm of 0.700 moldm-HC1 reacted
with all the CaCO3 in a sample of egg shell, calculate the
(1) mass of CaCO3 in the
egg
shells
(11) volume of CO2 evolved at s. t.p The equation for the reaction is
CaCO3 + 2HC1 CaCl2 + H2O + CO2 [H=10= 16. Ca =40]​
