Unidentified #2 bag from 2007 with black and yellow pieces and many black 1x2 clip pieces! It's driving me crazy! I recently purchased LEGO pieces from a local Goodwill. It looks like there's several Star Wars sets from 2007-2008 that are missing lots of pieces. I was assuming this bag was from a Star Wars set, but I'm not seeing anything that resembles the yellow pieces.
Welcome to Bricks.SE, Amy!

Indeed, this bag is not from a Star Wars set. It is from Exo-Force set 8117 Storm Lasher from 2007. This set contains both the 2 yellow pincer-like blades as well as the concave windscreen in trans-black, and many of the hinge pieces displayed in the left bottom corner of your picture.
