If the heat from burning 5300 g of C6H6 2C6H6I15O2g rightarr
     If the heat from burning 5.300 g of C6H6  2C6H6(I)+15O2(g) rightarrow 12CO2(g) + 6H2O(I) + 6542 kJ is added to 5691 g of water at 21  degree  C, what is the final temperature of the water? The specific heat H2O(I) is 4.184 J/(g.  degree  C).
