Question
Procedure was; add 50 mL of distilled water to the calirimeter (styrofoam cups). And add 5 gram of unknown salt to the calorimeter and stir slowly with the thermometer. Question is; if some slat were accidentally spilled as it was transferred from the balance ti the styrofoam cup would the calculated enthalpy of the unknown salt be too high or too low? Explain.

Question is; if some slat were accidentally spilled as it was transferred from the balance ti the styrofoam cup would the calculated enthalpy of the unknown salt be too high or too low? Explain.Explanation / Answer
The value will be low. Because the enthalpy value obtained is for the taken amount of salt. Here due to accidental spill, we introduced less amount into the water but if we do a calculation for 5grams, ignoring the spill, the answer would be low.
