What is the degree of the relationship type in the following ER diagram?

Information for questions 1-3 The following table has data about three countries: A, B, and the U.S. It lists the three countries’ nominal GDP per capita and PPP-adjusted GDP / capita. Countries A and B use their own currencies (we can call them A$ and B$), but we have no information about any exchange rates among these three currencies. All values on the table have already been converted to US$, so they can be compared. You can, and should, compare values that are all in U.S. dollars. GDPs of three countries Country Nominal GDP / capita (in US$) PPP-adjusted GDP / capita (in US$) Country A $ 15,000 $ 28,000 Country B $ 20,000 $ 22,000 U.S. $ 60,000 $ 60,000 A resident of country A travels to country B. She is an average citizen of A, with an income of $15,000. While traveling in country B, she exchanges her A$ for B$ to cover her expenses in hotels, restaurants, gift shops, and so on. While in country B, she will experience a _______ in her standard of living, in that she can afford _______   goods than she could afford at home with the same amount of money. (Hint: look at the PPP corrections for countries A and B: which country has prices more different than the U.S. prices? Or does it?)

A general reaction written as A + 2B → C + 2D is studied and yields the following data: [A]0[B]0Initial Δ[C]/Δt 0.150 M0.150 M8.00 × 10–3 mol/L·s 0.150 M0.300 M1.60 × 10–2 mol/L·s 0.300 M0.150 M3.20 × 10–2 mol/L·s What is the overall order of the reaction?

The reaction 2H2O2 → 2H2O + O2 has the following mechanism:H2O2 + I– → H2O + IO– H2O2 + IO– → H2O + O2 + I– The catalyst in the reaction is:

At a particular temperature, N2O5 decomposes according to a first-order rate law with a half-life of 3.0 s. If the initial concentration of N2O5 is 1.0 × 1016 molecules/cm3, what will be the concentration in molecules/cm3 after 16.1 s?

Which of the following statements concerning equilibrium is not true?

Consider the following reaction:          2HF(g)  H2(g) + F2(g)          (K = 1.00 x 10–2)Given 1.00 mole of HF(g), 0.362 mole of H2(g), and 0.750 mole of F2(g) are mixed in a 5.00 L flask, determine the reaction quotient, Q.

Consider the reaction 2O3(g) → 3O2(g). The following mechanism is proposed:                    O3   O2 + O                    O3 + O → 2O2If we assume the second step of the mechanism is the rate determining step and the first step is a fast equilibrium step, which of the following rate laws is predicted by this mechanism?
