What is the charge of $$96$$ amu of $$S^{2-}$$?

An electrochemical cell can behave like an electrolytic cell when:

Aluminum is obtained by 

Number of coulombs required to deposit $$90\ g$$ of $$Al$$ when the electrode reaction $$Al^{3+}+3e\rightarrow Al$$ is

The emf of Deniell cell is 1.1 volt.If the value of Faraday is 96500 coulombs per mole, the change in free energy in kJ is :

If the following half cells have the $$E^o$$ values as
$$Fe^{+3} + e^- \rightarrow Fe^{+2}$$; $$E^o= +0.77V$$ and $${Fe}^{+2}+2 {e}^{-} \longrightarrow {Fe}$$ ; $$E^o= -0.44 V$$ The $$E^o$$ of the half cell is $$Fe^{+3} + 3e^- \rightarrow Fe$$ will be:

When ammonia is added to a solution, its $$pH$$ is raised to $$11$$. Which half-cell reaction is affected by the $$pH$$ and by how much?

Electrolysis is :

Conductivity of water (in $$\Omega ^{-1}\,cm^{-1}$$) is 

The reaction : $$H_{2}(g)+2Ag(Cl)(s)\rightarrow 2H^{+}(aq)+2Cl^{-}(aq)+2Ag(s)$$ occurs in the galvanic cell
