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 many impurities 7uj )*r p20epmzag3kxthat willg xp0j*p a e27zmu3rk) also combust. This will result 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.
