A Design a Proposal for a Hot Pack and a Cold Pack Based on the data in Data Table 2 for calcium chloride and ammonium chloride determine which compound to use and what quantity of each compound will be needed to make a chemical hot pack and cold pack Both packs should be calculated based on using 100 g of water The hot pack should reach 60 C and the cold pack should go down to 3 0 C from a room temperature of 25 C Create a spreadsheet and graph for CaCl and NH CI Plot the mass on the x axis and change in temperature on the y axis for both graphs The slope will be the change in temperature per gram of salt dissolved Hot Pack Compound needed to achieve 60 C Grams needed per 100 g of water Cold Pack Compound needed to achieve 3 0 C Grams needed per 100 g of water DATA FROM TABLE 2 Calcium Chloride 65 kj mol
