Check the connection between guy and a goat. Hint: it's a movie in which he finds something about the goat annoying(check movie release poster). Now, think about this "problem" chemical cause. When you find the compound, stay in the group it represents and play around.

Do you know google's new reverse image search? You can find who the stamp is by just using that.

Silver is just mythical. I have done my conversions but the challenge says the reaction is endothermic whereas my calculations show it to be exothermic lol
