2. Industrial humidifiers has two inlet streams – 1. liquid
water and 2. drier air. The entering liquid water stream flows at
5.31 mol/min. The component flow rate of air in the drier air
stream is 44.3 mol/min. The exiting streams consist of a wetter air
stream and a liquid water stream. The exiting liquid water stream
contains 34.5% of the entering liquid water. The outlet streams are
in vapor liquid equilibrium at 42.8oC and 786 mmHg.
a) Draw the process flow diagram, number the streams, and label the
species in each stream.
b) Find the component mass flow rates (kg/min) of all four
streams.
c) The pressure of the outlet streams decrease by 5%, will the mole
fraction of water in the wetter air increase, decrease, stay the
same? Justify your answer.

1. Show the reaction, along with the transition state (‡), between 2-methyl-2-pentene and BH3 in THF. Then, show the subsequent reaction of the organoborane intermediate with H2O2 and OH-1. Explain why hydroboration is non-Markovnikov and forms a 2o alcohol. Refer to hydroboration in the chapter notes, the handout for example 8.2, and figure 8.4 in text. (2 pts)

If I have 2 samples of limestone, sample 1 weighing 0.732g and sample 2 weighing 0.825g. Both were dissolve do in15ml of 3.00M of HCL. 1.5g of (NH4)2SO4 was added to each sample. Then 20ml of 2.00M NH3OH was added to each sample. How do I calculate the moles of CaCO3 in limestone AND the mass of CaCO3 in limestone ?

Intra Corp. has the following operating data for the past 2 years: Year 1 Year 2 Return on Investment 10% 25% Residual Income $600 ? Required Rate of return 8% 10% Average operating assets ? $42,000 Sales in year 2 is $60,000 more than sales in year 1. The Company had the same capital turnover in both years.
(Q.) What is the sales margin in Year 2? Use two decimal places in the answer (for example, if the answer is 24%, key in "0.24").
