Problem Details

A mixture containing KClO3, K2CO3, KHCO3, and KCl was heated, producing CO2,O2, and H2O gases according to the following equations:


2KClO3 (s) 2KCl(s) + 3O2 (g)
2KHCO3 (s) → K2O(s) + H2O(g) + 2CO2 (g)
K2CO3 (s) → K2O(s) + CO2 (g)


The KCl does not react under the conditions of the reaction. 100.0 g of the mixture produces 1.80 g of H2O, 13.18 g of CO2, and 4.10 g of O2. (Assume complete decomposition of the mixture.)
