E-85 is an alternative fuel for automobiles and light trucks that consists of 85.0% (by volume) ethanol (C2H5OH), and 15.0% gasoline.  When ethanol burns completely it produces CO2 and H2O. The balanced equation for the burning of ethanol isC2​H5​OH+3O2​-->2CO2​+3H2​OThe density of ethanol is 0.790 g/mL.   How many moles of carbon dioxide are produced by the complete combustion of the quantity of ethanol in 8.00 gallons of E-85 fuel?      _mol CO2

The combustion of propane produces carbon dioxide and steam.             C3H8(g)  +  5 O2(g)  →  3 CO2(g)  + 4 H2O(g) All of the following statements concerning this reaction are correct EXCEPT a) three molecule of carbon dioxide are formed per one molecule of propane consumed. b) five molecules of oxygen are consumed per one molecule of propane consumed. c) four moles of steam are formed per five moles of oxygen consumed. d) the combined mass of reactants consumed equals the mass of products formed. e) three grams of carbon dioxide are formed per five grams of oxygen consumed.

In the following reaction how many moles of CO wil be produced when  8 moles of C react?                           C      +     SO2   --------->     CS2   +     CO
