A mixture containing KClO3, K2CO3, KHCO3, and KCl was heated, producing CO2,O2, and H2O gases according to the following equations: 2KClO3(s)2KHCO3(s)K2CO3(s)→→→2KCl(s)+3O2(g)K2O(s)+H2O(g)+2CO2(g)K2O(s)+CO2(g) The KCl does not react under the conditions of the reaction. 100.0 g of the mixture produces 1.70 g of H2O, 12.66 g of CO2, and 4.00 g of O2. (Assume complete decomposition of the mixture.) You may want to reference (Page) Section 3.7 while completing this problem. a. How many grams of KClO3 were in the original mixture?...
