Show how each of the following strong electrolytes "breaks up" into its component ions upon dissolving in water by drawing molecular-level pictures.
a. NaBr f. FeSO4
b. MgCl2 g. KMnO4
c. Al(NO3)3 h. HClO4
d. (NH4)2SO4 i. NH4C2H3O2 (ammonium acetate)
e. NaOH
Now explain why strong electrolytes 'completely' dissociate when mixed in an aqueous solution.
A recovery of 95% of particles greater than 100 μm is required. The minimum operating temperature will be 10 °C and the maximum 30 °C. Design a hydro cyclone system to handle 1200 liters/min of this slurry.
calculate masses of alcohol and ether produced, per 1000 kg of allyl chloride fed to the reactor.
Determine the composition of streams leaving the first FV unit. Determine the amount of liquid and vapor leaving the first FV unit.
Use the three-element Kelvin model to describe the stress relaxation of a biomaterial of your choice. Using a stress response curve from the literature, compute the model spring constants K1 and K2 and the viscous damping coefficient b.
Then the monkey on the right begins to climb the rope while the monkey on the left simply holds on. When the right monkey has raised himself through height h(relative to the floor), what has been the change in the position of the left monkey?
The helicopter can produce a maximum downward air speed ( v = 24 m/s ) in a slipstream of a diameter ( D = 9 m). Knowing that the weight of the helicopter and the crew is ( 15 kN ) and assuming air density rho = 1.21 kg/m^3 ), determine the maximu..
The blower-motor combination used at the gas inlet has an overall efficiency of 50 percent. Estimate the power cost per 8000 operating hours for forcing the air through the packing if the cost of power is $0.08 per kilowatt hour.
The machine is now run as a motor while taking 10 kW at 250 V. Neglect the brush contact drop. Determine the speed of the motor.
Neglecting stator resistance and rotational and stray-load losses, and assuming constant rotor resistance, calculate the starting torque and the maximum torque in per-unit of full-load torque, as well as the slip at which the maximum torque occurs..
A point charge Q1 = -5 nC is located at (6, 0, 0). Compute the voltage vba between two points a(1, 0, 0) and b(5, 0, 0). Comment on whether point a is at a higher potential with respect to point b.
to find the force between the wires. Discuss the nature of the force when the wires carry currents in the same direction, and in opposite directions.
