the mass of Cuo obtained by heating of metallic with nitric acid and subsequent ignition was found to be 2.7 gram in another experiment , 1.15 gram of copper oxide on reduction yield 0.92 gram of copper show that data illustrates the law of constant composition |

Answer» Molecular MASS of CaCO3=40+12+(16*3)=100gSo, we don't have to do much in this QUESTION!!!Now, we KNOW ,CaCO3 (by HEATING)→CAO + CO2 (↑)therefore, 1 mole of CaCO3 gives 1 mole of CaO…..So, 1 mole of CaCO3 = 100g of CaCO3AND 1 mole of CaO = (40+16)g=56g of CaOSo, 100g of CaCO3 gives 56 g of CaO on heating …..Thanks for a good question… |
