Show that the following observations are in agreement with law of conservation of
mass.
1.Observation-10g of CaCOꝫ(Calcium carbonate) on heating gave 4.4g of CO₂(carbon dioxide) and 5.6g of CaO(calcium oxide).
2.Observation-5g of CaCl₂(calcium chloride) on reaction with 8g of Na₂SO₄(sodium
sulphate) gives 4g of NaCl(sodium chloride) and 9g of CaSO₄(calcium sulphate).
