### How do manganese nodules in the ocean sustain oxygen production without depleting over geological time scales?

They may very well have "depleted" during the experimental study, as oxygen levels tended to increase only by a finite amount over a limited time period (which varied from sample to sample), ...

### What could be causing these random, pseudo-blister defects when electroplating galvannealed steel?

Hydrogen blistering occurs when hydrogen ions are also plated out into the steel electrode. Corrosion frequently causes this blistering (see image, Ref 1). A lengthy review of hydrogen blistering can ...

### Limiting current vs Steady-state limiting current

Short answer: yes, they are the same. The general equation for the limiting current is usually written this way : $i_{l} = nFAmC^*$, with m the mass tranfer coefficient. This is the maximum current ...

### Automate electrolysis for hydrogen generation via humidity

Using some hygroscopic material to catch water vapour from air to perform electrolysis is an active area of research. This hygroscopic material can double as the electrolyte. Here's an article ...

### Automate electrolysis for hydrogen generation via humidity

Your overall idea is possible (if just barely feasible), but not using $\ce{CaCl2}$ for the electrolyte: $\ce{Cl2}$ would be evolved, not $\ce{O2}$, and the electrolyte would be rapidly depleted. ...

### Calculate the solubility product of calomel using potential?

The rection you have setup is incorrect as you cannot just assume activity of electron to be $1$. Since, the calomel half-reaction is set against SHE, the reaction will be At cathode: \$\ce{Hg2Cl2(aq) ...
