Use the equation below to determine how many grams of co are needed to react with an excess of fe2o3 to produce 104.9 g fe? you must show all of your work to receive credit.

molar mass information:
fe= 55.85 g/mol
c= 12.01 g/mol
o= 15.99 g/mol

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
