Heat of formation of SO_(4) is -298 kJ. What is the heat of combustion – InterviewSolution

1.	Heat of formation of SO_(4) is -298 kJ. What is the heat of combustion of 4g of S
Answer» `+37` KJ `-37.25` kJ `+298` kJ 18.6 kJ Solution :`S+O_(2)rarrSO_(2), DeltaH=-298 kJ` HEAT of formation of `SO_(2)` is also the heat of combustion of sulphur. `because` heat of combustion of 32 g S = (-298) kJ `THEREFORE` heat of combustion of 4g `S=((-298)xx4)/(32)=-37.25 kJ`.
