If acetaminophen happened to be the unknown component how would one separate it from sucrose and aspirin? Generate a separation flow chart based on the experimental procedure above (just like the flow chart illustrated in the coordinator's online lecture notes).
what is the resulting total pressure of gases in the now-joined flasks? (assume no reaction between the gases and that the gases behave ideally)
The metal hydride LiH has a density of 0.77 g/cm3 . The edge of the unit cell is 4.086 . If it is assumed that the H ions define the lattice points, does the compound have a face-centered cubic or a simple cubic unit cell?
