Many home barbeques are fueled with propane gas C3H8 What mass of carbon dioxide (in kg}) is produced upon the complete combustion of 18.9 { L} of propane (approximate contents of one 5-gallon tank)? Assume that the density of the liquid propane in the tank is 0.621 { g/mL}. (Hint: Begin by writing a balanced equation for the combustion reaction.)
The stereochemistry of the more highly substituted alkenes is difficult to define using the cis and trans designations. Therefore, a more systematic manner of indicating stereochemistry in these systems has been developed that uses an E and Z nome..
