An insulated container is used to hold 45g of water at 34.8C. A sample of copper weighing 8.20g is placed in a dry test tube and heated for 30 mins in a boiling water bath at 100C. If the heated copper is then placed into the water in the insulated container, given that the specific heat of copper is 0.385J/(gC), calculate the maximum temperature of the water after the copper metal is added.
Given that the partition coefficient for a solute is K in a water-ether solvent extraction system, is it more effective to do one extraction with V mL of ether or three extractions with V/3 mL of ether
