The following molecular equation represents the reaction that occurs when aqueous solutions of silver nitrate and chromium(III) iodide are combined.
Given a solution containing 0.01M of lead chloride and 0.01M of lead chromate, calculate the concentration of Pb2+. Using the Ksp(PbCl2)=1.7x10^-5 and Ksp(PbCrO4)=1.77x10^-14. What is the solid remaining?
Mass(volume)of cold water:75.0g Temperature of cold water: 23.0 degree celsius Mass(volume) of hot water: 75.0g Final temperature: 41.1 degree celsius find the temperature change and the calorimeter constant.
This procedure is potentially very lucrative because, after an initial extraction of energy from the groin, no fossil fuels would be required to keep the device running indefinitely. Would you invest in this idea? State your conclusion clearly and..
