Homework Help: Chemistry 2

Posted by Pat on Thursday, September 13, 2007 at 6:22pm.

A mixture containing KCLO3, K2CO3, KHCO3, and KCL was heated, producing CO2, O2, and H2O (water) gases according following equations:

2KCLO3 -> 2KCL + O2
2KHCO3 -> K2O + H2O + 2CO2
2CO3 -> K2O + CO2

The KCL does not reacnder the conditions of the reaction. If 100.0g of the mixture produces 1.8g of H20, 13.2g of CO2, and 4g of O2, what was the compttion of the original mixture?(assume complete decomposition of the mixture)

someone please show me how to do this!
* all O'in the equations stand for oxygen, nothing means 20, its 2O, 2 then oxygen comes after.
