Answer : The for the reaction is, 54.89 KJ
Solution : Given,
Mass of ZnS = 48.7 g
Molar mass of ZnS = 97.474 g/mole
First we have to calculate the moles of ZnS.
The balanced combustion reaction is,
From the given reaction, we conclude that
As, 2 moles of ZnS gives energy = 220 KJ
So, 0.499 moles of ZnS gives energy =
Therefore, the for the reaction is, 54.89 KJ
