Question

1. in the combustion of propane (c3h8), which gases are produced? oxygen and carbon dioxide carbon monoxide and water vapor methane and oxygen carbon dioxide and water vapor

Explanation:

The balanced - chemical equation for the complete combustion of propane ($C_3H_8$) in the presence of oxygen is $C_3H_8 + 5O_2
ightarrow3CO_2+4H_2O$. In a complete - combustion reaction of a hydrocarbon like propane, carbon dioxide ($CO_2$) and water vapor ($H_2O$) are produced.

Answer:

D. Carbon dioxide and water vapor
