Assuming:

Upward → positive (+) value of ΔH

Downward → negative (-) value of ΔH

ΔHA = ΔHB + ΔHC 

ΔHA = ΔHB + ΔHC
-ΔHC           - ΔHC

ΔH = ΔHA - ΔHC

Problem Details

Match each chemical reaction with the correct diagram according to Hess' Law

ΔHC = -ΔH+ ΔH

ΔH = ΔHA  + ΔHC

ΔH= ΔH- ΔHC

ΔH = -ΔH- ΔHC 

ΔH= -ΔH+ ΔHC

ΔH= ΔHA  + ΔH

ΔH = ΔH- ΔHC 

ΔHC = -ΔH- ΔH
