A charge neutral macrocyclic ligand having four donor atoms froms a red, diamagnetic complex of Ni(II). The counter ions for this complex is the very weak Lewis base, ClO4-. When ClO4- is replaced by thiocyanate, violet complex forms.
a. Draw the structures of the red and violet complexes such that thier geometires can be decerned based only on your drawings.
b. Draw the d-orbital slitting diagrams of the red and violet complexes such that the relative energies of the orbitals in the two complexes can be compared.
c. Wse your orbital diagrams to show were the d electroms reside in each complex. Explain your electron configurations.
d. describe an experiment that you could do to test whether your predicted electron configurations are reasonable. Show what the results of this experiment would be for the d electron configureation that you showed in part c

1. Define the ff:
A. Heat-
B. Heat capacity-
2. Why is it desirable to have the water a few degrees colder than room temperature when the initial temperature is taken?
3. Why is the mass of the outer shell of the calorimeter and the insulating ring not included in taking data for Calorimetry?
6. Why should the hot metal be dry before it is introduced into the cold water? 837 calories of heat are required to heat 100.00 grams of copper from 0.0 C to 100.0 C. What is the specific heat of copper?
***Determining specific heat through insulating through coffee cup. Aluminum is heated and then immediately put in a thermal cup containing water.. Shaked.. then Final Temperature is determined.
4. What does this experiment show about the specific heat of water?
5. How does the conductivity of the metal used in this experiment affect the accuracy of the results?

*MiniTab Is Required for this question** Suppose that a precise measuring device for new hair growth has been developed and is used in the experiment described in exercise 1922. The percentages of new hair growth for the 30 pairs of men involved in the experiment were recorded. Do these data allow the chemist to conclude that drug B is more effective?

We consider the experiment of picking a point at random from the interval (0, 1). The sample space for this experiment is the interval (0, 1). We consider three sequences of events in this sample space En = ( 1 n , 1) Fn = (1 − 1 n , 1), Gn = ( 1 2 − 1 2n , 1 − 1 2n ), n positive integer. (a) Is (En) ∞ n=1 increasing, decreasing, both, or neither? (b) Is limn→∞ En defined? If so, what is it (express your answer in interval notation). (c) Is (Fn) ∞ n=1 increasing, decreasing, both, or neither? (d) Is limn→∞ Fn defined? If so, what is it (express your answer in interval notation). (e) Is (Gn) ∞ n=1 increasing, decreasing, both, or neither? (f) Is limn→∞ Gn defined? If so, what is it (express your answer in interval notation).

Determination of an Equilibrium Constant
1. What is meant by a reversible reaction?
2. True or False : The
numerical value of the equilibrium constant for
a given reaction only changes
if the temperature
changes.
3. Which component of the reaction mixture was it
that was titrated with
sodium hydroxide?
A. Acetic acid B. Isopropyl alcohol
C. Water D. Phenolphthalein
4. Why was it necessary to wrap your rubber stopper in plastic wrap?
5. Why was it necessary to titrate a blank sample
solution, that is, a sample
of distilled water which contain only sulfuric
acid?
6. List two advantages of using a buret for measuring
reaction volumes as
opposed to maybe a graduated cylinder. (Precision and accuracy are
not exceptable answers)
7. What is a catalyst and how and why was a catalyst
needed in this
experiment?
8. When would you want to use a pipet instead of a
buret in an experiment?
