You have proven sulfanilamide is capable of forming a stable and selective crystal lattice. Draw additional molecules of sulfanilamide and hypothesize the intermolecular interactions that are most important for providing a stable and selective crystal structure
How much heat is required to warm 211 g of ice from -45.9°C to 0.0°C, melt the ice, warm the water from 0.0°C to 100.0°C, boil the water, and heat the steam to 173.0°C?
Calculate ?G for 1.00 mole of an ideal gas as the external pressure is increased from 1.00 bar to 2.00 bar at a constant temperature of 298.0K.
Adrenaline is the hormone that triggers the release of extra glucose molecules in times of stress or emergency. A solution of 0.64 g of adrenaline in 36.0 g of CCl4 elevates the boiling point by 0.49°C. What is the molar mass of adrenaline?
A mixture of carbon and sulfur has a mass of 9.0 g. Complete combustion with excess O2gives 22.7 g of a mixture of CO2 and SO2
