CaO(s) + H2O(l) - Ca(OH)2(s)
enthalpy of rxn= -63.7 kJ/molrxn
Calcium oxide, CaO(s), has been proposed as a substance that can be used to heat water quickly for portable heating packs or for cooking. When placed in water, Cao(s) reacts as shown by the equation above.
A student wants to design a heating pad that could heat a 150.0 g sample of water from 25.0°C to 60.0°C.
Calculate the amount of heat, in joules, that the water must absorb for its
temperature to change by this amount. (Assume that the specific heat capacity
of the water is 4.18 J/gK).
