What's wrong with my car? on 2004 Dodge Intrepid

I just bought a 2004 dodge intrepid and it was working fine the heat was working and I didn't have any problems. But bout 3 weeks later my car didn't have any heat and it was smoking from under the hood. I looked under the hood and I see like some liquid not sure what it is but kinda worried. Please help.

Got to see it to tell you anything! Let a mechanic look at it, low on any fluids?
