A PC store sells many types of computers. The PC can have either 16 or 8 gigabytes of memory.

The quality of the PCs can be either New, Refurbished, or Dented.

The price list is given as follows:

Memory size/Status New Refurbished Dented

16 gigabytes 849.99 729.99 609.99

8 gigabytes 699.99 579.99 439.99

Determine the price of a given PC dependent on the user inputs. The sale tax is 9.25% for each PC.

User input can only be 8 or 16 for memory size and 'N', 'R', or 'D' for quality (upper-case). The input quantityt should be 0 or positive.

If any user input is not correct, display an error message and skip all calculation.

All currency amount should be displayed with 2 digits in decimal fraction.

Here are several separate program sample runs. There is No need to use loop for repetition.

Determine Kc for the reaction (justify all your calculations):

½ N2(g) + ½ O2(g) + ½ Br2(g) NOBr(g)

From the following information at T=298 K

2NO(g) O2(g) + N2(g) Kc = 2.1 x 10^30

NO(g) + ½ Br2(g) NOBr(g) Kc = 1.4

What is the molality of a solution that has been prepared by mixing 53.6 g of sodium chloride with 464 g of water?

1) A 150.0 mL solution was prepared by mixing 100.0 mL of 1.00 M HONO (Ka = 4.5 x 10–4 ) with 50.0 mL of 1.00 M NaNO2 . Calculate the pH, [HONO], and [NO2–], once equilibrium has been established.

2). What is the pH, [OH^–], [HF], [F^–], and the percent ionization of a solution prepared as 0.50 M HF ? (HF: K_a = 7.2 x 10^-4)

50 M HF ? (HF: K_a = 7.2 x 10^-4)

3. Consider the reaction:

CO(g) + H₂O(g)    CO₂(g) + H₂(g)

At 800 K the equilibrium constant, K = 16.

If your reaction vessel initially contains 0.050 M CO, 0.050 M H₂O, 0.30 M CO₂ and 0.30 M H₂. What are the equilibrium concentrations of all of the components?

4. What is the pH of a saturated solution of Mn(OH)₂ ( K_sp = 2.0 x 10^–13)?

Mn(OH)₂ (s)   Mn²⁺ (aq) + 2 OH^-(aq)     

5) The weakest strong acids is Nitric acid, with a K_a = 240. The % ionizations of strong acids are rounded off to 100%. Calculate the % ionization of 0.100 M nitric acid without rounding.

Why is good documentation important in your research reports? Explain why recommendations should be specific and actionable. Provide at least two examples of recommendations that meet this standard.

please write a paper that argues either for or against government intervention in foreign trade. Describe both the benefits and the problems that can occur when governments interfere with foreign trade, describing the different barriers that governments can impose and also the steps they sometimes take to encourage international trade.

What is the current thinking on the little hierarchy problem in light of a potential Higgs mass above 120 GeV? A few years ago, at least, I remember various phenomenologists saying that this at least makes life rather difficult for the MSSM.

• A migrating fish would be rapidly transferring substances across cell membranes. These substances would include sodium, water, carbon dioxide, oxygen, and steroids. Which of those would be most likely to be moved via active transport? Why?

Goldstein's Classical Mechanics has a puzzling few sentences in his discussion of orbits.

Referring to the case of orbit where the energy is low enough for the orbit to be bounded, he says :"This does not necessarily mean that the orbits are closed. All that can be said is that they are bounded, contained between two circles of radii r1 and r2 with turning points always lying on the circles."

Doesn't "bounded" automatically mean "closed"? The object cannot escape from the attractive force and hence returns over and over. At least, that is my understanding of the terms. Wikipedia says "The orbit can be open (so the object never returns) or closed (returning), depending on the total energy (kinetic + potential energy) of the system." But it also says "Orbiting bodies in closed orbits repeat their paths after a constant period of time." So the only way out I see is if a closed orbit is a special case of non-precessing bounded orbit.
