Ompound a (c6h6) undergoes catalytic hydrogenation over lindlar catalyst to give a compound b which in turn undergoes ozonolysis followed by workup with aqueous h2o2 to yield succinic acid and two equivalents of formic acid. in the absence of a catalyst poison hydrogenation of a gives hexane. propose a structure for compound a.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b
