5) A Canadian corporation needs to borrow $1.5 million (Canadian $). Given that the rate of interest in Canada is 5% and the exchange rate between the Canadian $ and the US$ is 1.5 (1 US$ = 1.5 Can$), the Canadian corporation decides to borrow the equivalent (US $1 million) from a US bank at 4% with semi-annual payments for two years. The exchange rate between the Canadian $ and the US$ is flexible and can change at any time. Our corporation is facing an exchange rate risk and wishes to protect itself against that. How would it do this using a cross-currency swap with the above information?

CHEM 10040 The Molecular World 2023/24 Tutorial Problem Set 3 Write your answers on paper, convert them to a single pdf (e.g., using CamScanner) and upload them to BrightSpace as a single file by 12.00 noon on Monday the 6th of November. Xarelto (Rivaroxaban) $6.58 billion CI OMe Eliquis (Apixaban) H2N $9.871 billion Shown above are structures of two drugs for cardiovascular disease along with their US sales in 2018. Please draw out one of the structures and answer the questions below with reference to these structures. 1. On the structure you have drawn: a) identify two polar covalent bonds b) identify one functional group (circle the atoms involved and name the functional group) 2. In relation to the structure you have chosen: a) circle the parts of the molecule that are present in both structures. b) using two of the strategies we have met in lectures draw a modified structure that could be tested as part of a lead modification strategy if your chosen structure was a lead compound (i.e., your modified structure should have two modifications). Highlight where you have made changes by circling them in the structure drawn and labelling the type of change made. 3. The $pK_a$ of an acid in water at 20 $^\circ$C is 3.0. a) Write the equation that relates $K_a$ to $pK_a$. b) Thus, calculate the $K_a$ of the acid. c) Is this acid stronger or weaker than acetic acid? d) Write the equation that relates $K_a$ to concentration of species in solution.
