Aliquid mixture containing 30 wt% acetone (a) and 70 wt% water (w) is fed to a distillation column operating at steady-state. a top product stream contains 90 wt% a while the bottom product stream contains 5% of the a fed to the column and the rest with. your rotameter indicates you are pumping 100 l/h of the mixture into the column. the specific gravity of the feed is 0.75. how many independent material balances can be written?

3.09 lab: reaction of metals 1 which combinations of substances resulted in a chemical change? for each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. make a general statement about the reactivity of the metals in this experiment.
