Use Hess's Laws to solve. What is your final answer (delta H) for the
reaction? Write your answer as a whole number with the correct sign and
units. *
C 4
What is AH for the following reaction?
4C (s) + 5H, (g)
You are given the following reactions:
C(s) + 0, (g) CO, (9)
AH = -393.5 kJ
4CO, (g) + 5H0 (1)-- CH (9) + 6420, (g) AH =-2657.4 kJ
H (g) + 1/20,(g)-H0 (1)
AH = -241.8 kJ
