when i ride i hear the chain hitting something but when i look there is nothing for it to hit!
could this be that the chain is to loose ?

any help would be good as it is very annoying when you are going down a huge rocky mountain thing!

Most likely the chain is hitting the chainstay. If you are going along a flat road you should not hear the chain hitting. BUt if you aregoing down a rocky mountain road you will hear it. Only way to really get rid of it is to go single speed with no tensioner. Since The chain is under tension so you can have the length needed to run multiple gears. In turn this means that when you hit large bumps etc the chain will bounce around.

Get an old tube and wrap your chainstay and zip tie it down. It could also be the derailuer hitting the chainstay. That happens sometimes on some Specialized frames.

Lizard Skins makes a neoprene chainstay cover with a velcro seam, cost about $15. Another good thing to do is to shift into the big ring when descending, this will remove much of the slack in the chain!

Yep. I use one on my RB. It's recommended if you have carbon chainstays. I prefer it to the stick-on plastic protectors because it also deadens the noise as well as the impacts.

You could also go down to your local hardware store and buy a section of clear vinyl tubing, (http://www.homedepot.com/prel80/HDUS/EN_US/diy_main/pg_diy.jsp?CNTTYPE=PROD_META&CNTKEY=misc%2fsearchResults.jsp&BV_SessionID=@@@@0595464887.1065766002@@@@&BV_EngineID=cccgadcjikhmihlcgelceffdfgidgnj.0&MID=9876) slit it down the middle and zip tie it around the chainstay for a cheap Mcguyver -esque fix.
