Write a balanced equation describing the dissolution of calcium hydroxide in water Acording to solubility rules, should Ca(OH)2 be soluble or insoluble in water. Explain Predict the sign +- of delta G for the process. Predict the sign + - of delta S for this process.
Classify each process as exothermic or endothermic: freezing of water endothermic boiling of water exothermic break down of food during digestion exothermic a person running exothermic a person growing endothermic turning graphite into diamond endothermic heating with a furnace exothermic
The easiest way to determine whether a process is exothermic or endothermic is to note the change in temperature in a calorimeter; a positive temperature change indicates an exothermic process while a negative temperature change indicates an endothermic process. Select the Experiment tab in the Simulation, and then click Run Demonstration. Perform the described tasks while specifically focusing on the third demonstration, where LiCl is dissolved in water, paying attention to the temperature change and the microscopic view. Match the...
