ANSWER:Solution 82P:
Here, we are going to determine the ∆H°rxn for the given reaction.
Step 1:
The enthalpy change of the reaction can be obtained from the equation.
We have to draw the Lewis structure for each of the molecule in the reactants and product.
Total valence electrons of HCN = 1+ 4 +5 =10
