You add an aqueous solution of lead nitrate to an aqueous solution of potassium iodide. Draw highly magnified views of each solution individually, and the mixed solution including any product that forms. Write the balanced equation for the reaction. What do you think of your sketch, and what do you think this says about the nature of chemical reactions.
Determine the concentration of the exhaust gas and Determine the flow rate of exhaust gas through the smokestack.
Gas Absorption and Transfer Operations: Column Diameter Calculation, A gas absorption column to handle 3630 kg/hr of a gas is being designed. Based on pressure drop, entrainment and foaming considerations
where and Qp are constants for a given gas-polymer pair. Consider the diffusion of hydrogen through a poly (dimethyl siloxane) (PDMSO) sheet 20 mm thick.
Strontium fluoride, SrF2, has a Kspvalue in water of 2.45 × 10-9at room temperature. Calculate the solubility of SrF2in water. Express your answer in units of molarity.
Plot the system curve on the pump characteristic given in Figure and determine the operating point and pump efficiency. Properties of the fluid: density 900 kg/m3, viscosity 1.36 mN m-2 s.
In the chlorination of ethylene to produce dichloromethane (DCE), the conversion of ethylene is reported as 99.0%. If 94 mol of DCE are produced per 100 moll of ethylene reacted, calculate the selectivity and the overall yield based on ethylene. T..
Develop the designed circuit using breadboard in the laboratory. Available thermal sensor can be used in the circuit. Discuss the effect of resistors on calibration of the sensor with specific emphasis on the sensitivity of the instrument.
Using the information in the above table to show how the specific volume of each liquid varies with temperature. You should plot a graph for each liquid and use this graph to estimate the exact value of a at 50°C for each liquid.
You decide to take 2.00 mL of the solution and add an excess of a concentrated sodium chloride solution. You obtain a solid with a mass of 3.407 g. What was the concentration of the original lead(II) nitrate solution?
Chlorine is to be removed from a vent stream by scrubbing with a 5% w/w aqueous solution of sodium hydroxide. The vent stream is essentially nitrogen, with a maximum concentration of 5.5% w/w chlorine.
Application of reverse osmosis principles for the desalination of sea water
