Question

Do it yourself hand warmer packers can be made using ice pellets (CaCI2) and nested ziplock bags. A smaller inner bag holds water and a larger outer bag holds CaCl2. Squeezinf the bags so gang the inner bag bursts allows water to dissolve the CaCl2 the delta h solution of this is -81.6KJ/mol
What is the final temp of the solution made by dissolving 10.00g of CaCl2 in enough water to make 55.6 mL of solution both at 24.0 C initially assume a heat capacity of 4.05 j/g C for the solution and a density of 1.09 g/ml Do it yourself hand warmer packers can be made using ice pellets (CaCI2) and nested ziplock bags.

Explanation / Answer

?H = -81.6 kJ/gmol

Final Temp if

m = 10 g CaCl2 are dissolved in water

V = 55.6 ml of solution

Ti = 24
