D-Pinitol is a hexahydroxy cyclohexane, whose structure is shown below. On the templates provided, draw the two chair conformations that are in equilibrium for D-pinitol. Circle the most stable conformation. 2. Assign R, S absolute configurations to each indicated chirality center in the molecules below. On the work you upload, you may write each letter with your configuration. For example, A = R or A = S and so on. The configuration of this carbon atom (A) is ________. The configuration of this carbon atom (B) is ________. The configuration of this carbon atom (C) is ________. The configuration of this carbon atom (D) is ________. The configuration of this carbon atom (E) is ________.

The tаble belоw presents lоng run mаcrоeconomic dаta for 2 hypothetical nations A & B: Economic Performance Indicators A B Nominal GDP growth 15% 7% Inflation 10% 2% Nominal Interest rate 4% 4% Unemployment rate 12% 5% Population growth rate 1.5% 2.5% Assume that both nations start with real GDP of $3,000 per citizen. Calculate and type the answers that would fill the blanks below, assuming that the data above apply for every year considered. Use the approximations formula: Economic growth = %Δ in nominal GDP - %Δ in price level - %Δ in population and the compounding formula P(1+r)n where P is the current amount, r is the rate (in decimal) and n is years, where applicable. A B Economic growth rate [EGRA] [EGRB] Years required for real per capita GDP to double [YRSA] [YRSB] Real per capita GDP 140 years later (correct to 2 decimal places) [RGDPA] [RGDPB]
