change in heat?

Question

1.calculate the work change in H at 298K and change in E for the combusition of one mole of sucrose at 25 degree C and 1atm pressure (use change in H sucrose = -2218kJ/mol)
C12H22O11(s) + 12O2(g) --> 11H2O(l) + 12CO2(g)
a. w= 0kj H=-5648kJ, and E=-5648kJ
b. w=0kj, H=5648kj and E=5648kj
c. w= 5648kj, H= 0kj and E= -5648kj
d.w=0kj , H= 0kj, and E= 0kj
e. none of the above.

2. A 73g sample of water with a temperature of 5.0 degree C is added to 271g water at 59degree C in an insulated container. What is the final temperature after thermal equillibrium is reached?
a. 0.021 degree C
b. 17 degree C
c. 32 degree C
d. 48degree C
e. 224 degree C

Answer 1

2.Temp = ((73g X 5.0) + (271g X 59))/ (73g + 271g)
