An aqueous solution of sodium hydroxide contains 20% NaOH by mass. It is desired to produce an 8% NaOH solution by diluting a stream of the 20% solution with a stream of pure water.(a) Calculate the ratios (g H2O/g feed solution) and (g product solution/g feed solution).(b) Determine the feed rates of 20% solution and diluting water needed to produce 2310 lb/min of the 8% solution.

Q.1) In the experiment, you wrap a piece of copper wire around your magnesium strip to suspend the magnesium inside the eudiometer. Why is copper wire a good choice for this task? Group of answer choices It conducts electricity very well It reacts strongly with the acid It does not react with the acid It is much heavier than Mg   Part B) A 45 mL sample of a dry gas is collected at 380 torr and 25 °C. Calculate the volume of the gas sample (in mL) at STP.   Part C)Using the data provided in Table 3 in the handout (also provided below), calculate the vapor pressure of water at 21.0 °C.

A two-unit separation is used to dewater ethanol. First, a 320 mol/hr feed(Stream 1) of a mixture of 0.750 mole fraction ethanol (E) and 0.250 molefraction water (W) is fed to a distillation column. The extractive agent, benzene(B), is added to the distillation column in a mixture of 0.940 mole fractionbenzene and 0.060 mole fraction water (Stream2). This mixture consists offresh benzene (Stream 3) and the recycle stream of benzene and waterrecovered from the separator (Stream 4). The company wishes to produce a0.98 mole fraction ethanol (0.02 mole fraction benzene) product stream fromthe overhead of the distillation column (Stream 5). The bottoms product(Stream 6), containing just benzene and water, is sent to the separator. Thecomposition of the benzene/water mixture leaving the bottom of the separator(Stream 7) is 0.86 mole fraction benzene and the balance water. Some of thebottom stream leaving the separator is recycled (Stream 4) and added to thefresh benzene feed to the column…

A 50% NaCl solution should be concentrated in a triple effect evaporator like the one shown in the figure (each individual evaporator is known as an effect). In each effect an equal amount of water evaporates. Determine the exit concentration of effect 2.

Material Balances question

4. A 100 kmol/h stream that is 97 mole% carbon tetrachloride (CC14) and 3% carbon disulphide (CS2) is to be recovered from the bottom of a distillation column. The feed to the column is 16 mole% CS2 and 84% CC14, and 2.5% of the CCI4 entering the column leaves in the overhead (top of column). a) Draw and label a flowchart of the process and do the degree-of-freedom analysis. b) Calculate the mass and mole fractions of CC14 in the overhead stream and determine the molar flow rates of CC14 and CS2 (kmol/h) in the overhead and feed streams

6.48 In a system with a purge, the amount of inert in the purge line needs to meet the amount of inert in the feed, in order for the system to operate properly and for no inert material to build up in the recycle lines.  For the diagram given below, and an overall conversion of 90% for the limiting reactant, calculate the flows of nitrogen, hydrogen, ammonia and inert (in units of moles/hr) for the purge stream 4.  At the condenser, all of the ammonia product goes to the “liquid product” stream, and none of the ammonia goes towards stream 3.
