However there are only four questions that have both tags, and three of those are mine, probably in anticipation that they might be merged in the future.
- Do we need both as tags?
- If so, what is the difference?
- If not, should they be merged?
Here are questions that are tagged chemistry, categorized by how well I estimate that astrochemistry would suffice and a separate chemistry tag would not be needed. I'm wondering if "chemistry" is even the proper tag or something like "geochemistry" or "planetary-chemistry" might be a better name for it.
astrochemistry tag will probably suffice:
- Have caged molecules ever been observed in space? unless Rob Jeffries’ “clathrates” end up being on/inside planets
- Why was helium hydride (HeH+) the universe's first molecule?
- What is the organic material in Saturn's rings?
- Is the composition of stars in future made of more and more heavy elements?
- What is the distribution of organic compounds in the Milky Way Galaxy?
- What happens to oxygen produced on the Sun (or other stars)?
- Why are there no green stars?
- Why is there so much methane in space?
- Internal heat and planetary differentiation
Not sure, depends on what astrochemistry means:
- Is there any difference among exoplanets in composition due to host star?
- What is germane doing in the atmosphere of Jupiter?
- What aliphatic compounds were found on Ceres, and how where they identified?
- What factors influence the Widmanstätten pattern in iron meteorites?
astrochemistry probably not the proper tag:
- What could be the possible origin of boron found in the Martian soil if not from ancient groundwater?
- Massive degraded impact crater on Mercury - chemical evidence?
- Statistics of elements abundance in exoplanets
- Can a planet with a hydrogen atmosphere have a water ocean with dissolved oxygen? (closed)
