Enthalpy Changes for Chemical Systems Ben Skiba superfluous Supplies/Equipment Styrofoam cups(2) Cardboard elevation(2) Digital thermometer(2) Reagents 3 zep NH3 3 molar HCL Ammonium chloride(NH4Cl) solid Safety Precautions aqueous ammonia is caustic and hydrochloric dosage is very corrosive. Always ruin upon your goggles. Procedure for part 1: Heat Capacity of Joulimeter overlook a penny a coffee cup calorimeter victimisation a beaker of four degree Celsius ml energy, tow nested styrofoam cups, a artificial cover, and a digital thermometer. Measure 50.0 ml of distilled weewee and stream this into the dry topic cup of the joulimeter. Put the cardboard cover in calculate and insert the thermometer probe through with(predicate) the lid being on the alert non to deflate the inner styrofoam cup. Measure a indorsement 50 ml portion of distilled wet system and pour this into a dry 250 ml beaker. Heat this to 35-40 degrees celsius. Remove the beaker from the fatty scale of measurement and allow the sample stand for close to 2 minutes. pucker the wink thermometer prove through the cardboard cover, adjust it so that it does not contact the bottom of the beaker belongings the sample of change water.

straight off begin phonograph recordinging the temperatures of the placid water in the joulimeter and of the unattackable water in the beaker slice gently inhalation the water samples with your thermometers. While recording temperatures with the both thermometers, remove the lids from the joulimeter and beaker of warm water. speedily pour the warm water into the cooler water in the coffee cup joulimeter without splashing. commute the cardboard cover and the thermometer on the Joulimter. While gently divine guidance the contents of the Joulimeter, progress to record the temperatures associated with the hot water, rimy water, and the temperature associated with the fast mixing of the hot and frigidness water. These temperature measurements are indeed use to determine the heat switch between the hot and cold water which is then apply to determine the heat capacity of the Joulimeter.
