A calorimetric determination of specific heat and enthalpy of solution was performed.
How would each of the following procedural changes affect (higher than the correct value, lower than the correct value, or no change) the value of the specific heat of the metal determined in this experiment? Explain reasoning.
1.) The tube containing the metal was not left in the water bath long enough to reach the same temperature as the bath (100 C).
2.) Some of the water was spilled before the final weighing.
How would each of the following procedural changes affect (higher in magnitude [so if the value is negative, it will be more negative] than the correct value, smaller in magnitude than the correct value, or no change) the value of the enthalpy of solution determined in this experiment? Explain reasoning.
1.) The mixture of water and ionic solid was not stirred sufficiently so as to dissolve the solid completely.
2.) Not all of the solid in the beaker was poured into the calorimeter.
