Change in Gibb's free energy of system (ΔG) = ΔH - TΔS.........(Eq. 1)
Now, if magnitude of ΔG <0, then reaction is spontaneous.
if magnitude of ΔG > 0, then reaction is non-spontaneous.
At equilibrium, ΔG = 0
When at boiling point, liquid state is in equilibrium with vapour state. Hence, it present case ΔG = 0
∴ Eq 1 becomes, ΔH = TΔS
here, ΔH = 58.2 kj/mol (Given),
∴ At T = 83.4 oC = 356.4 K, ΔS = 0.1633 kj/mol.K

In this reaction, acts as an acid and acts as a base.
Molecular equation: 
Total ionic: 
Net ionic:
Answer:
25
Explanation:
With Protons being the only charged particles in the nucleus, their overall charge is zero. This is because electrons and protons have opposite charges. The nuclear charge of ANY atom is given by its atomic number.
