Asked by Ominyi John David
A mixture of salt way in 13.78g contains CACO3 with gaseous impurity it was heated to a constant mass and the resolve was reacted with H2SO4 to form 6.78g of CASO4. Calculate the percentage purity of the calcium trizoncarbonate four I'm the mixture (ca=40, c=12, H=1, O=16, sulphur=32)
Equation of the reaction cao
1. Calcium oxide + H2SO4→CASO4 + H2O
2. CaCo3→CaO2 + O2
Equation of the reaction cao
1. Calcium oxide + H2SO4→CASO4 + H2O
2. CaCo3→CaO2 + O2
