Question- It was found that the concentration of anions formed from the partial dissolving of an ionic solid to form saturated solutions is less in the presence of a common ion than in pure water. Why is this true?
Please perform what you can and illustrate your work so I can follow. Thanks
A 64.3-g piece of aluminum at 94 °C was immersed into 70.0-g water at 25.0 °C. The water temperature rose to 36.4 °C. Calculate the molar heat capacity of the metal.
