    Looks like the rear hanger. If you google the make and model of the rear mech and the bike model it should hopefully come up with what you want.
    Too many bikes according to Mrs O.

    yes, you simply get a new one, take the old one off and replace with new.
    10 mins and about £15 for the part

    The rear derailleur might be toast too. When you get everything installed, make sure the derailleur H and L screws are set up correctly or the rear derailleur could hit the spokes (when on the largest rear cog) and rip the lot off again.

    You are very lucky that your back wheel is still OK.
