Which type of fuel is most likely to undergo incomple+e0gu6bj mixf :q)ot ;w.,unf d)vqhsbu*o ,y t/vzz 11qy8q. te combustion?
A. Propane
B. Coal
C. Natural gas
D. Crude oil
参考答案: B
本题详细解析:
Coal is an impure form of fossil fuel and therefore contains man afxn.q7f,.tbygk3 2 by impurities that will also combust. This will resu.3anqy f 7f,bg2.tbxklt in many byproducts from the impurities combusting, so more oxygen is required to combust the hydrocarbons completely.
Propane, natural gas, and crude oil are all cleaner fuels (have fewer impurities). So, they are more likely to undergo complete combustion with a comparable amount of oxygen per mole of fuel.
