In one beaker: 10 mL of .005 M KMnO4 + 8 mL 1M NaOH + 15 mL .01M Na2SO3 In another bkr: 10 mL of .005 M KMnO4 + 15 mL .01 M Na2SO3 In another: 10 mL .005 M KMnO4 + 10 mL 1M H2SO4 + 25 mL .01 M Na2SO3 Write/balance 3 redox reactions (half-reactions..
Acetominophen is a weaker acid than carbonic acid but asprin is a stronger acid than carbonic acid. prepare the flow chart diagram like the one in this experiment, showing the procedure that can be used to separate the a mixture of sucrose, aspiri..
Calculate the final temperature of 32 mL of ethanol initially at 11 degrees C upon absorption of 562 J of heat.
A hot-air dryer is used to reduce the moisture content of 1500kg/min of wet wood pulp from 0.75 kg H2O/kg dry pulp to 0.15wt% H2O. Air is drawn from the atomosphere at 28C, 760mm Hg, and 50% relative humidity, sent through a blower-heater, and the..
