Got a few ideas:

You can have "eix" give details for all the packages in a "group" in one go
though. Try:
# eix sci-chemistry/
(Yes, use a training slash "/" )

To install all the packages in "sci-chemistry/" you can do the following:
# emerge -va `eix sci-chemistry/ --only-names`

Be prepared to have to unmask a lot of packages.

To get a list of all the sci-chemistry/ packages installed (eg. still to check
and/or already selected to keep:
# eix -I --only-names sci-chemistry/

Hope these help with what you're trying to do.
