If some of the salt remains adhered to the weighing paper (and therefore is not transferred to the calorimeter), will the enthalpy of solution for the salt be reported too high or too low?

I think the correct answer from the choices listed above the answer would be the second option. If some of the salt remains adhered to the weighing paper, then the enthalpy of solution for the salt be reported would be too low since not all of the salt that is supposed to be the sample was not included in the process. Hope this answers the question.

Olá. porque a reação na temperatura é muito rapida a do copo : )
