popping clunking sound FREAKING OUT

[gt5094stang]

long story short i'm hereing a loud clunking or popping sound every few seconds at low and high speeds. My chain is a little loose but not tight at all and when i put the bike on a stand i spin the rear wheel and can here and feel the popping clunking sound from the rear. This happened on the way to school and luckly my friend lives down the street and stop by his house and did all this right before class. As of right now im in class and have been doing some research online and don't now if its the chain, sprockets, or rear wheel bearing......

Any ideas??? Im leaning toward chain and sprockets but has anyone had this happen to them??? How do i look for wear on the teeth and if the chain is tight in one spot or several can it cause this.

Its not quiet at all its pretty loud and happens in neutral also when it was on the stand

FYI i have an f3 rear wheel but i have had the conversion done for almost a year and this has never happend till today

Frozen link in the chain. Spin it slowly and look for a link that doesn't bend easily.
