Above question is incomplete. Complete question is
<span>What is the missing number in the nuclear reaction 175 78 pt -- 4 2 He plus 76 Os?
....................................................................................................................
Solution:

Reaction involved in present nuclear event is 
</span>175 78 Pt      →          4 2 He          +          76 Os

In above nuclear reaction, atomic mass number of Os is missing. The atomic mass number of Os = 175 - 4 = 171

Thus, complete nuclear can be written as
175 78 Pt      →          4 2 He          +       171  76 Os

We know that the relationship between enthalpy and entropy is:
ΔS = <span>ΔH/T
Therefore, both the change in enthalpy and the change in entropy will have the same sign. Now, considering each change:
