1.8-3.0 quartet and singlet, I can't remember which one went where
10.0-12.0

Definitely wasn't E isomer . Out of the two Z isomers , you just had to look at the one where the numbering of the chlorine was correct .

-5 for entropy
-2 for whether it would increase or decrease
-2 for rate
-1 for units of k
-1 for anomalous result
-3 for safety

That's 76/90
What do you think that'll be
That would be an A* go you

Coffee granules dissolve in water, so they contain polar molecules. The oil is non-polar, so the two would be immiscible. So a separating funnel would be suitable? :dontknow:
