is there an alarm that can be set off on my phone so i can find it

Yes.

• Go to http://www.icloud.com/find Locate your iPhone and choose "Play Sound."
• Even simpler, consider simply phoning the iPhone's telephone number.

If the phone is not on silent, you can call it. If it's on silent, then you can go to find my iPhone and have it locate your phone and after locating your phone, you can tell it to play a sound which will have it emit a sound.
