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 fo nrr8;9 ajrgh7maa;x+24 g cwyssil fuel and therefore contains many impurities that will also combust. This will x7;am nc48+rrwagg9; 2y hajrresult 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.
