Ethanol is normally concentrated by distillation of aqueous solutions, but the composition of the vapor from aqueous ethanol is 96 percent ethanol and 4 percent water. Therefore, pure ethanol cannot be obtained by distillation. Commercial ethanol contains 95 percent by volume of ethanol and 5 percent...
10. The bad news is, the alcohol you just drank contains so much ethanol that it's going to bind with that nasty formic acid rampaging through your body, hence you're just gonna pee it out, harmlessly. 而坏消息是,你刚才喝的酒里所含的乙醇,正好可以和你体内那些可恶的甲酸牢牢结合在一起,...

While methanol has one carbon atom, ethanol, the next largest and derived from the pure hydrocarbon ethane, has two. The chemical formula for ethane is CH3CH3(also written C2H6); each carbon atom is bound to three hydrogens and to the other carbon atoms. The formula for ethanol is therefor...
What is the unit for volume in the metric system? What is the weight of the ethanol that exactly fills a 200.0 mL container? The density of ethanol is 0.789 g/mL. How much water should be added to 32 mL of 18% alcohol solution to reduce the concentration to 16%? a) 4 mL b) 6...
