Propane c3h8 is a hydrocarbon tht is commonly used as a fuel
(a)write a balanced equation for the complete combustion used propane gas.
(b) calculate the volume of air at 25c and 1.00 atmosphere that is needed to completely combust 25.0 grams of propna. assume that air is 21.0 percnt o2 by volume. (hint: we will see how to do this calcullation in a later chapter on gases -- for now use the infomation that 1.00l of air at 25c and 1.00atm contains 0.275 g of o2 pe liter.)
(c) the heat of combustion of propane is -2,219.2 kj/mol. calculate the heat of formation, hof of propane given that hof of h2o = -285.8 kj/mol and hof of co2 = -393.5 kj/mol
(d) assuming that all of the het releasd in burning 25.0 grams of propane is transferred to 4.00 kilograms of water calculate the increase in temperature of water .
