If you wanted to know how much carbon there is in a 100kg person, what information would you need? Try to calculate the amount of carbon in a 100kg person.
Assume that fructose is a molecular solid and does not ionize when it dissolves in water.
Selective oxidation of hydrocarbons is a known method to produce alcohols. However, the alcohols react with the oxygen to produce aldehydes, and the latter react with oxygen to produce organic acids. A 52 mol/s stream consisting of 90.0% ethane an..
