Question to answer after EXPERIMENT OF SPECTROPHOTOMETRIC DETERMINATION OF TRACE Fe

Principles The purpose of this experiment is to determine the concentration of iron present as a trace constituent (ppm) in an aqueous sample by a spectrophotometric method. One of the most sensitive methods for the determination of iron involves the formation of the orange-red iron (II) orthophenanthroline complex. This complex has an absorption maximum at 508 nm, is stable over a long period of time, and follows Beer's Law quite faithfully.

The chemistry involved is straightforward. Hydroxylamine hydrochloride is used to reduce all Fe3+ present to Fe2+. Since orthophenanthroline (abbreviated as phen) is a weak base and an acid medium must be used in order to prevent precipitation of the iron as Fe(OH)2, the principal complexing species is the phenanthrolium ion (phenH+ ). The complex formation reaction:

Fe2+ + 3phenH+  Fe(phen)3 2+ + 3H+

has an equilibrium constant of 2.5 x 106 , so complex formation may be considered quantitative. Although pH control is not essential, too high of an H+ concentration (pH<2) can inhibit formation of the complex, while too high of a pH can cause the loss of iron by precipitation. Thus, the solution is buffered to be to about a pH of 3.5.

Since the system obeys Beer's Law, above, a plot of absorbance at 508 nm versus iron concentration yields a straight line. Thus, one can prepare a set of standard solutions of known concentrations, establish a straight line, and prepare the unknown solution in exactly the same way. If the absorbance of the unknown solution is measured, the unknown concentration may be determined from the analytical curve generated with the standard solutions.

Questions:

1. The ferrous ammonium sulfate used as a standard in this experiment is not of primary standard quality, yet you were not instructed to standardize this reagent 81 before use. Why is it not necessary to standardize this analytical reagent before use in this experiment? Explain.

2. Describe two reasons why deviations to Beer's Law (i.e. nonlinearity) can occur.

3. The sensitivity of spectrophotometric methods can greatly exceed sensitivities attainable with classical wet chemical methods. How do the Fe concentrations analyzed in this spectrophotometric experiment compare with the Fe concentrations used in the redox titration experiment? Be quantitative!

Using a light source with a power density of 500 W / m2 for a PV module with a surface area of 0.92 m2, the measured values at the Tcell = 55 ˚C are given as follows.
 The current and voltage value corresponding to the maximum power point is Vmpp = 30 V and Impp = 1.45.
 The open circuit voltage is Voc 38 V and the short circuit current is Isc 1.70.
 The temperature coefficient for this module Voc is 0.16 V / ° C (ignore for Isc).
According to this, calculate the following.
a) What is the efficiency of this module for the specified measurement conditions?
b) Calculate the Voc, Isc, Vm, Im, and Pmax values for this module in standard test measurement conditions (STC).
c) What is the efficiency of the module in STC?

(a) Find the equilibrium solution, or critical point, of the given system.

(b) Use a computer to draw a direction field and phase portrait centered at the critical point.

(c) Describe how solutions of the system behave in the vicinity of the critical point.

x′ =−0.25x−0.75y+8, y′ =0.5x+y−11.5

(d) Let x= x_c+u and y= y_c+v, where x_c and y_c give the critical point you found in (a). Plug these into the system and show that you obtain a homogeneous system u′ = Au for u = (u v)^T .

(e) Solve the resulting homogeneous system for u and v, and show that the solutions you obtain match the phase portrait that you generated in (b).

A ballistic pendulum consists of a large heavy mass, M on the end of a very light rod of length L. The rod is free to pivot at the top and the mass is attached at the bottom, so it hangs like a pendulum. A second mass, m, is fired horizontally at speed v straight into the large mass, and they stick together. The pendulum swings to a maximum angle ?m.

a)Show that you can measure v by measuring ?m, that is obtain an expression for v in terms of M, m, L, g and ? m.

b)Look up the mass and speed of a bullet, and figure out how mass

ive M should be if L is about 0.25 m and we want a maximum angular displacement no greater than 45?.

We have to calculate the value of Power of an electric DC motor IN WATTS made from scratch. The only known values that we have are: The Voltage (V) which is 9V and the current (I) that we are using which is 3 A, also the value of "n" which is n= 90.16 m (the number of turns of the wire used in the motor)

I already asked here for this problem and someone answered this:

Voltage = 9 V, current = 3 A, number of turns = n = 90.16

Power of motor = n*V*I = 90.16*9*3=2434.32 Watt

But I don’t think this is correct since the motor has power in and power out. Can someone else help? Thank you!
