    okay so question that i remember are here..

    Refrigirant …another one was delta T question…ugh so annoying tht was…another was carbon was 80% H as 20% find the molecular formula…
    I guess the answer was D c4H10.?? Is that what you guys got

    For section B q part iii how to show volume was 12cm3 and molarity was 2.00. That crazy salt question. I didn't finish it Couldn't do the yield as time was over.

    2nd question all about organic chem..didin;t get the dimer right and the octane part ..other was comparatively easy substitution and addition parts. 3rd question about potassium and argon were easy. %abndance I got wrong how did you guys calculate. How to get pure crystals part was easy. Atom economy was easy. What else was in the paper?
