Presume the structure of compound Z C11H12O4 which has UV-Vis absorptions above 275 nm. Its IR spectrum depicts bands at 3208, 3175, 3100, 2947, 2908, 2847, 2753, 1740, 1730, 1650, 1634, 1590, 1565, 1476, 1455, 1230, and 1105 cm-1. Its 1H-NMR spectrum shows delta 1.2 (d, 6H), 3.8 (m, 1H), 7.3-7.8 (ABq, 4H), 10.7 (s, 1H).
Calculate delta G for the reaction when the partial pressures are PH2 = 0.25atm, PCO2 = 0.81atm, PH2O = 0.62atm, and PCO = 1.20 atm.
Calculate the partial pressure of each gas and the total pressure if the temperature of the gas is 18 degrees celsius

A compound contains 10.13% C, and 89.87% Cl (by mass). Determine both the empirical formula and the molecular formula of the compound given that the molar mass is 236g/mol
Consider a chromatogram containing a single analyte with retention time of 4 minutes. The mobile phase elution time is 0.2 minutes. What is the capacity factor (k') for the analyte in question?
Draw every stereoisomer for 1,2-difluoro-1,2-dimethylcyclopentane. Use wedge and dash bonds for the substituent groups
A 0.4780-g sample of impure Ca(OH)2 is dissolved in enough water to make 57.00 mL of solution. 20.00 mL of the resulting solution is then titrated with 0.1140-M HCl.
1-When 30.5 mL of 0.565 M H2SO4 is added to 30.5 mL of 1.13 M KOH in a coffee-cup calorimeter at 23.50°C, the temperature rises to 30.17°C. Calculate H of this reaction per mole of H2SO4 and KOH reacted.
