Given xdg-open and an extension, is there a way to get the application which xdg-open is set to for that particular extension?
For example given xdg-open and .jpg the result is eog.

Method 1
AFAIK the choice of action is based on the file’s mimetype rather than its extension.
At least on Ubuntu, you should be able to use the query action of xdg-mime to show the default application for a specific mimetype
$ xdg-mime query default image/jpeg eog.desktop
You can check the mimetype for a particular file using xdg-mime query filetype e.g.
$ xdg-mime query filetype kqDRdnW.jpg image/jpeg
or using the file command e.g. file --mime-type <file>
See man xdg-mime for further usage information.
Method 2
To query the mime type used by an existing file by using xdg-utils, it works as:
$ xdg-mime query filetype yourfile.xxx
You can also set a new default, for instance to change an associated desktop entry by setting Thunar – a modern file manager for the Xfce Desktop Environment – as the default file browser you should enter:
$ xdg-mime default Thunar.desktop inode/directory
Or for example to set the default application for http(s):// internet protocols, you can use:
$ xdg-mime default midori.desktop x-scheme-handler/http OR $ xdg-mime default midori.desktop x-scheme-handler/https
