Use only the first decimal points (X.X) for atomic masses. R = 8.314 L*kPa/mole*K. In a reactor at 350.0 kPA and 95 °C, HCl adds to acetylene by the following reaction:2HCl(g) + C2H2(g) --> C2Cl2H4(g)39.1 g of HCl and 39.1 g of acetylene are placed into the reactor. What is the limiting reagent? What is the final volume of the system?
A binary mixture with components A and B is to be separated in a distillation column to obtain 95 mol%. A as the top product. The binary mixture has a con stant relative volatility AB = 2. The column feed is a a - saturated liquid containing 50 mol % of A. Under the usual simplifying assumptions such as constant molal overflow, negligible heat loss, ideal trays, the mini mum reflux ratio for this separation is (rounded off to one decimal place)
Q/ ture or false 1- The difference between wet and dry corrosion, in the first case it occurs in the presence of moisture and the second in its absence * 2- It is necessary to fix the names of the equipment on the illustrative curve of the industrial process * 3- The flow curves are classified according to the number of reactors and the mechanism of separation or non-separation of the products * 4- In the processes that involve the purification of raw materials and products, it is preferable to purify the raw materials by adsorption, while the products are purified by washing, stripping and absorption. 5- The amount of dissolved substances in well water differs greatly from surface water due to the difference in temperature. * 6- The biological waste has no significant effect on the efficiency of the flow, but rather its effect on the toxicity of the water used for industrial purposes. 7- Several methods are used to remove unacceptable odors from water, including chemical…

A 0.512 g sample of a commercial phosphate detergent was ignited at a red heat to destroy the organic matter. The residue was taken up in hot HCl, which converted the P to H3PO4. The phosphate was precipitated as MgNH4PO4.6H2O by addition of Mg2+ followed by aqueous NH3. After being filtered and washed the precipitate was converted to Mg2P2O7 by ignition at 1000 0C and the residue weighed 0.1151g. (a) What is the Gravimetric Factor to convert Mg2P2O7 to P? (b) Calculate the percent P in the sample could you type it out please
- The major objective of a roasting process is to eliminate the Sulphur contained in the concentrate andto provide a calcine. In a roasting plant, 1000 kg per hour of molybdenum(IV) sulphide (MoS2) is roastedwith 25 % excess air to obtain MoO3 calcine in a chamber-type roasting furnace. Preheated air entersthe reactor at 400 K while MoS2 enters at room temperature. After the process, the waste gases leavethe reactor at 1000 K, and the calcine leaves at 850 K.a) Draw process flowsheet and heat balance diagram (ref. temp is 298 K) b) Calculate the amount of off-gas per hour in moles. c) Calculate the amount of calcined MoO3 per hour in kg.
A mixture of methane and air is capable of being ignited only if the mole percent of methane is between 5% and 15%. A mixture containing 9.0 mole% methane in air flowing at a rate of 7:00 x 102 kg/h is to be diluted with pure air to reduce the methane concentration to the lower flammability limit. Calculate the required flow rate of air in mol/h and the percent by mass of oxygen in the product gas. (Note: Air may be taken to consist of 21 mole% O2 and 79% N2 and to have an average molecular weight of 29.0.)

A solution containing 100 lbm KNO 3/100 lbm H 2O at 80°C is fed to a cooling crystallizer operated at 25°C. Slurry from the crystallizer (KNO3 crystals suspended in saturated solution) is fed to a filter, where the crystals are separated from the solution. Use the solubility data in Figure 6.5-1 to determine the production rate of crystals (lbm/lbm feed) and the solid-to-liquid mass ratio (lbm crystals/lbm liquid) in the slurry leaving the crystallizer.
Two tanks are connected by a series of pipes as shown below. Tank 1 initially contains 150 grams of salt dissolved in 20 liters of water, while tank 2 contains 50 grams of salt dissolved in 10 liters of water. Beginning at time t = 0, pure water is pumped into tank 1 at a volumetric flow rate of 3 liters per minute. This causes brine to flow between the tanks, and to flow out of both tanks at the volumetric flow rates shown in the Fig. 2. Determine the salt concentration in each tank (C, and C2) at any time t>0.
