How many liters of chlorine gas, Cl2, can be obtained at 40C and787 mmHg from 9.41 g of hydrogen chloride, HCl, according to the following equation?
2KMnO4(s) + 16HCl(aq) à 8H2O(l) 2KCl(aq) 2MnCl2(aq) + 5Cl(g)
Determine experimentally the value of a resistor that when placed across the battery will make a measurable change in measured battery voltage. Keep the voltage decrease from open circuit value to 10% or less.
A resistive temperature sensor is modeled as R(T) = 100 +0.0039(T-25)+1.0x10^-5(T-25)^2 where T is in degrees C. Calculate the tempco and sensitivity at T = 50 degrees C.
What do they mean by these two statements. For example, are they asking us to keep Voltage or Current constant in either statement and vary the Resistance finding the unknown Voltage or Current or what
Charges +Q and +3Q are seperated by a distance 2m. A third charge is located such that the electrostatic system is in equilibrium. Find the location and the value of the third charger in terms of Q.
(c) Use a single 4-to-1 multiplexer with an active low enable and an active high output and a minimum of additional gates. Show the function expansion both algebraically and on a Karnaugh map.
an amplifier with a 1 MHz bandwidth and a 20 mV input signal. The input noise = 1 mV, output signal = 6.0 mV, and output noise = 1 mV. Find: (a) SNR at the input (b) SNR at the output (c) Noise figure
a. Evaluate X(s) and specify its region of convergence. b. Determine the values of the finite numbers A and t0 such that the Laplace transform G(s) of g(t) = Ae^âˆ'5tu(âˆ't âˆ' t0)
Three identical constant pitch thin helical coils (having a pitch 3mm, axial length 450mm and inner diameter 20mm) are positioned along a common axis. The axial distance between the first and the second is 55mm
Write a HCS12 assembly-language program that copies values from ARRAY1 to ARRAY2 until it copies 10 values, or a value in ARRAY1 that is equal to zero.
Find c > 0 such that the area of the region enclosed by the parabolas y = x^2 - c^2 and y = c^2 -x^2 is 30. c= 6. Find the area of the region bounded by the parabola y = 4 x^2, the tangent line to this parabola at (3, 36) and the x axis.
Unpolarized light is incident on three polarizers: The first making an angle of 0 degrees with the vertical; the second making an angle of degrees with the vertical; and the last one making an angle of 90 degrees with the vertical.
A 50 ohmlossless air transmission line is terminated in a load impedance ZL = 12.5 + j20 ohm. Find the following using a Smith Chart: the load admittance YL. the closest distance to the load plane where the normalized admittance on the line is 1 + j..
