Tim is trying to determine the molar heat of dissolution of ammonium chloride through coffee cup calorimetry. Identify all of the following three errors that would lead to an overestimate in the molar heat of dissolution of ammonium chloride: 1) The thermometer used to measure temperatures consistently underreported the true temperature by 1 degree celsius 2) The ammonium chloride sample tested was contaminated by table salt 3) Exactly 10% of the water in the calorimeter evaporated before the ammonium chloride was added
