When propane is burned in air in a process known as combustion it produce carbon (IV) oxide and water
the word equation is as follows,
propane + oxygen--->carbon (IV) oxide + water
chemical equation is as follows
2C3H8 +7O2---> 3CO2 + 8 H2O
hence 2 moles of propane reacted with 7 moles of oxygen to give 3 moles of CO2 and 8 moles of H2o
