A gaseous mixture containing 50 mol% hydrogen and 50 mol% acetaldehyde (C2H4O) is initially contained in a rigid container at a total pressure of 760 mmHg absolute. The formation of ethanol occurs according to C2H4O + H2 C2H6O. After some time, it was noted that the total pressure in the vessel had dropped to 700 mmHg absolute. Calculate the degree of completion of the reaction, at that time, under the following assumptions: (a) all reactants and products are in the gaseous state,and (b) the gaseous mixtures were at the same temperature when the pressures were measured.
Deer ticks can carry both Lyme disease (L) and human granulocytic ehrlichiosis (H). In a study of ticks in the Midwest, it was found that 16% carried L, 10% carried H and 25% that had either L or H carried both.

Determine the value of the output voltage due to the voltage source only (Vol), and due to the current source only (V02).
determine the efficiency of a high frequency induction furnace which takes 10 minutes to melt 1.815 kg of aluminium the input of the furnace being 5 KW and the initial temperature 15 deg.
Problem on complex power, An electric load operates at 240 volts. The load absorbs an average power of 8Kw at a lagging power factor of 0.8.
A HCS12 ATD is set to 8-bit unsigned mode. A temperature sensor measuring 0 to 100 degrees with an output of 25 mV/degree is attached to the input. The ATD low voltage reference is attached to ground and the high voltage reference
What causes the current gain to decrease both in the case of a low collector current and at a high collector current?
a three phase motor operates at 70% efficiency, out of a 60Hz 480V balanced system of voltages. the motor takes a line current of 70A at a lagging power factor 65%. if the motor is rotating at 3500 rpm, and neglecting fraction, what is the torque ..
Desing a mod-16 asynchrous ripple up counter by using j-k flip-flops. You need to design a j-k flip flop first and use it as the component in mod-16 up counter design. Show both j-k flip-flop design implementation results .
