Why a yield sign and not a stop sign?

I grew up in a house on a side street. It's unimportant enough that even where it intersects other side streets, it is usually the one with the stop sign. But, at the only place in my neighborhood where it intersects one of the main streets, it has a yield sign. It's a pretty normal intersection. Th...

Re: Stable free oxygen on non-life planet

One instance where you might get the stable free oxygen is on a water world with oceans deep enough the bottom would consist of high-pressure ices.

Re: Delicious Martian Salt

One aspect of geochemistry that may be a factor is that on Earth we have continental crust with a roughly granitic composition, which is fairly rich in sodium. Weathering that granite, I figure, is a possible source of sodium for sea salt. Mars, as far as we know, has no granite. Most of its surface...

Re: Can Renesemee catch on?

While I would never change it, I do have one little pet peeve about my name: I have two middle names, but many official forms only allow for one middle initial.
What is fun is that my middle names make up a decent full name, as they are my grandfather's first name and my mother's maiden name.

Re: Uranium more Common than Zinc

Yes, solubility is a key thing. Uranium will form compounds and go into rock more readily than gold. Since it doesn't fit well in many crystal lattices it is also one of the last components to crystallize in a cooling magma. As a result it tends to get concentrated in continental crust.

Re: Safe electrolytes for electrolysis.

I expect the CO2 would form around the anode.
2H2O --> O2 + 4H+ + 4e-
So the pH around the anode would drop.

What of magnesium sulfate, then? It could release SO2 or form small amounts of sulfuric acid or magnesium bisulfate I imagine.
