I am a complete noob on this. But looks like sedimentary rock, and I say that because it seems to contain a bunch of bad-fitted particles, and then just got compressed enough to become a rock.
But most of the minerals and stuff can be looked up at mindat.org and they have a discussion forum where you can get help identifying stuff.
Here is just my noob thought, but if it was uranium, it should glow regardless of sulfuric acid or not. So I would say it isn't.
