Given that K a1 =5.9 x 10 −3 and
K a2 =6.0x10 −6, calculate the pH
after titrating 70 mL of 0.10 M H2SO3 with 50
mL of 0.10 M KOH.
Consider the titration of 30 mL of 0.10 M
H2CO3 with 50 mL of 0.10 LiOH. What would the
pH be if K a1 =6.0×10
−3 and K a2 =5.9×10
−7?
A chain of four matrices A1, A2,
A3 and A4, with order 3 X 4, 4 X 2, 2 X 8 and
8 X 7 respectively. Deduce m[1, 4] to
find best possible minimum number of multiplication
1. Derive expressions for the differential and common mode gains
of the amplifier and thence derive the common mode rejection ratio
(CMRR). Explain the design steps necessary to achieve a high
CMRR.
2. If the differential gain of the first stage of the amplifier
is 100 and the -& resistor values associated with the second
stage are R1= 15k, R2= 10.5k, R3= 200k and R4= 101k, calculate the
CMRR of the whole system.
3. Explain the operation of a Lock...
Given a second order process: 2 AB → A 2 + B 2 with k = 0.0908
M-1min-1; and the initial concentration of AB = 0.941 M, calculate
the concentration of A2 after exactly 20 min. Enter the result with
3 sig. figs. exponential notation and no units.
The filter coefficients of a second-order digital IIR filter
are: a0 = 1, a1 = -2, a2 = 2, b0 = 1, b1 = 1/2, b2 = 1/8. (a's are
numerator coefficents and b's are the denominator coefficients).
Compute the magnitude response |H(ej?)| where ? = 2.721
rad/sec.
You are given two arrays A1 and A2, each with n elements sorted
in increasing order. For simplicity, you may assume that the keys
are all distinct from each other. Describe an o(log n) time
algorithm to find the (n/2) th smallest of the 2n keys assuming
that n is even.
