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

Sphinxa [80]

Answer:

See explaination

Explanation:

The mole balance for a constant-volume batch reactor is given such as, For a first-order isothermal reaction, the time to reach a given conversion is the same for constant-pressure and constant-volume reactors. Also, the time is the same for a reaction of any order if there is no change in the number of moles.
