What does economic theory suggest is the long run relationship between changes in a country’s level of savings and its level of investment? Explain how your answer depends upon whether or not the economy is open or closed.

The following question requires you to upload a document with graphs showing changes over time. You will need to either use a picture from your phone or software to make your graphs. Use the money market and FX diagrams to answer the following questions.

This question considers the relationship between the United States ($) and the British Pound (£). The exchange rate is in dollars per pound. On all graphs, label the initial equilibrium point A and label all your axes correctly.

Illustrate how a temporary increase in the United States' money supply affects the money and FX markets. Label your short-run equilibrium point B and your long-run equilibrium point C.

Illustrate how each of the following variables changes over time (for United States): nominal money supply, price level, real money supply, United States’s interest rate, and the exchange rate .

Repulsion of electrons within two interacting molecules produces changes in electron distribution. This change in electron distribution creates temporary dipole moments. Which of the following does this explain?

Choose one or more:

A. This explains why the dipole-dipole attractive force between dimethyl ether and acetone does not entirely account for the attractive force between these molecules. B. This explains why ammonia and nitrogen gas exhibit an attractive force between them. C. This explains how the molecules hydrogen fluoride and methanol can exhibit uncharacteristically strong intermolecular forces. D. This explains how two noble gases' molecules can have an attractive force between them. E. This explains why long hydrocarbon chains have relatively high boiling points.

For each chemical reaction or physical change, record your observations (i.e. color changes, a ppt or solid formation, gas bubbles/odors, heat production, etc.). Observations should be detailed descriptions of WHAT you see, hear, smell, and feel. Recording a (+/–) is NOT an observation!

Short Answers:

1. Zn/HCl (single displacement) OBSERVATIONS:

2. NaHCO3/HCl (double displacement) OBSERVATIONS:

3. Sugar (C12H22O11) (decomposition) OBSERVATIONS:

4.CuSO4•5H2O (decomposition) OBSERVATIONS:

5. Fe/CuSO4 (single displacement) OBSERVATIONS:

6. NH3/HCl (combination) OBSERVATIONS:

7. Cu/HCl and Al/HCl (single displacement) OBSERVATIONS (for BOTH):

8. K2SO4/Ba(NO3)2 (double displacement) OBSERVATIONS:

QUESTIONS:

1. Which procedure(s) [#1 – #9] were NOT chemical reaction(s) as predicted above (there are two!)? Write the reaction(s) including physical states. How were you able to determine this (i.e. one is a physical change and one procedure did not react = no reaction)?

2. Which procedure(s) [#1 – #9] produced water(g) vapor (there are two possibilities!)? Write the reaction(s) including physical states. Which procedure resulted in a physical change?

3. Which procedure(s) [#1 – #9] produced a gas other than water(g) vapor (there are three!)? Write the reaction(s) including physical states. 4

. Which procedure(s) [#1 – #9] produced a solid from two non-solids (there are two!)? Write the reaction(s) including physical states.

5. Which procedure(s) [#1 – #9] produced heat (there is one!)? Write the reaction including physical states. 1/25/2018 9/9

6. Which procedure(s) [#1 – #9] produced copper metal (there is one!)? Write the reaction including physical states.

7. What is the difference between the denotations (aq) and (l)? Give a specific example of each one.

1. What sorts of mutational changes could occur in a gene for a cyclin-dependent kinase might lead to a cell becoming cancerous? Be as specific as you can as to what effect the mutational change would have on the kinase protein.

A spectrophotometer measures changes in absorbance of light over time. Species X has a molar absorptivity constant of 5.00x10^3cmM and the path of the cuvet that holds the mixture is 1.00 cm. Species X, a colored reactant, undergoes a first order decomposition reaction to form a colorless product. See data below.

a. Calculate the initial concentration of the colored species

b. Using the values given for concentration and time, calculate the rate constant for the first order reaction, include units

c. How many minutes would it take for the absorbance to drop from 0.600 to 0.075

d. What is the half life of the reaction? Include units.

e. The rate constant for this reaction was calculated at various temperatures. Using this data, the graph (to the right) was produced. T stands for temperature.

i.) Label the vertical axis of the graph.

ii.) Explain how you would use this graph to calculate the activation energy.

*Graph is a basic quadrant 1, x-y graph, where the x-axis is labeled (1/T) and the y-axis isn't labeled, a straight line goes down from left to right
