Question

          The following equation is the balanced combustion reaction for C6H6:

2C6H6+15O2= 12CO2+6H2O+ 6542 kj

          If 7.400 g of C6H6 is burned and the heat produced from the burning is added to 5691 g of water at 21           The following equation is the balanced combustion reaction for C6H6:

2C6H6+15O2= 12CO2+6H2O+ 6542 kj

          If 7.400 g of C6H6 is burned and the heat produced from the burning is added to 5691 g of water at 21      The following equation is the balanced combustion reaction for C6H6:

2C6H6+15O2= 12CO2+6H2O+ 6542 kj

Explanation / Answer

heat energy = 6542*7.4/(2*78) =310.325 kj

5691*4.18*(T-21)=310*325*10^3 j

T=34 c
