Using the henderson-hasselbach equation calculate the

Using the Henderson-Hasselbach equation, calculate the volume of 0.10 M Na2HPO4 and 0.10 M NaH2PO4 that would be required to make 100.0 mL of a 0.10 M (total phosphate concentration i.e. HPO4 + H2PO4) buffer with a pH of 6.91.

(Ka for H3PO4 =7.5x10^-3)

(Ka for H2PO4=6.2x10^-8)

(Ka for HPO4=4.2x10^-13)

Q : A cylinder of compressed gas rolls off a boat and falls to

A cylinder of compressed gas rolls off a boat and falls to the bottom of a lake. Eventually it rusts and the gas bubbles to the surface. A chemist collects a sample of the gas with the idea of trying to identify the gas.

Q : It operates at a power factor of 085 lagging at its rated

It operates at a power factor of 0.85 (lagging) at its rated conditions. Calculate the per-phase current that has to be carried by the cables to the power electronics converter and the step-up transformer located at the base of the tower.

Q : A balanced three-phase inductive load is supplied in steady

Q : The z-transform xz of a causal sequence xn has a zero at z1

The z-transform X(z) of a causal sequence x[n] has a zero at z1 = 0 and three poles at p1 = 3/4 and p2,3 = (1/2)(1 ± j). Determine the z-transform Y(z) of the sequence y[n] = x[n + 3], its pole-zero pattern, and its ROC.
