I have a project that i’m doing and I just need help with two questions I need help with.

I have to choose a superfund site, which i’ve done and I was just wondering if you could draw the structure for the contaminant trichloroethane and tetrachloroethylene. Also are there any classes of compounds present? If so can you give at least one example of a specific chemical that is part of that class?

The second I need help with is how to write the heat of formation of one of the contaminants and basically how to do number six. I left a file down below of all the contaminants that are part of the superfund site.
